Roomba vs Shark – Comparison Review
Hello folks. Today, we want to find out if iRobot has finally been brought down in this Roomba vs Shark robot vacuum comparison review.
You will agree with me that Roomba’s main advantage is the fact that iRobot has been around for longer. That’s the reason the likes of ILIFE, ECOVACS, and Neato Robotics have found it hard to keep up the pace.
However, it is a different scene when it comes to Shark ION. In as much as it is a new entrant in the robot vacuums market, it has been in the vacuum market for longer. It is only that it ventured into robot vacuums just the other day.
Roomba and Shark Cyber Monday Deals 2024
iRobot Roomba
iRobot rolled out its first Roomba in the market back in 2002, and though business was good at the time, the new vacuums market showed enough potential. It was only a matter of time before things started opening up.
One of the biggest differences between iRobot and Shark is the product portfolio. iRobot offers specialized floor vacuuming and mopping solutions. They have two main products; Roombas (robot vacuums) and Braava (robot mops).
Regarding technology, Roomba has exploited the latest innovations, and today it’s one of the best technologically advanced robot vacuums. In fact, it has the industry-leading technology in navigation, mapping, suction, and self-emptying mechanism.
Shark ION
On the other hand, Shark ION had begun business four years earlier before iRobot released their first Roomba.
But Shark ION had ventured in the regular vacuums market competing with the household names like Dyson, Bissel, Miele, and the rest.
For Shark ION, things are entirely different for the household appliances giant boasting an extensive product range. We have canister vacuums, upright vacuums, handheld vacuums, steam mops, and now, robot vacuums. Shark also manufactures a favorite juicer called SharkNinja.
In Shark ION, there is a lot to be desired, but this is something that we understand as it is just making its first footsteps in the flooded robot vacuums market. There is nothing unique in the design of Shark ION, just a replication of what we have.
Now, having looked at the overview of each brand, let’s look at some of the most popular models they offer.
Popular Roomba Models
Roombas are classified in series with the 400 Original being the first set of Roombas released in 2002, and the 900 Series is the latest, and perhaps the best robot vacuum at the moment.
Here is an overview of the popular Roomba models.
1. Roomba 600 Series (Roomba 694 vs. 675)
The Roomba 690 is the most popular model in this series and was released together with the 890. It came to replace the Roomba 650, and the only feature it adds is the WiFi for smartphone operation and Alexa compatibility.
This vacuum works with Virtual Walls and comes with one device included alongside a filter replacement.
When it comes to cleaning performance, the Roomba 690 is ideal for bare floors and picking up pet hair. When it comes to carpets, the suction power is average, so flashing dirt out of the carpet pile is quite overwhelming.
The Roomba 690 was replaced by the new Roomba 675, but then, there is no much the new model adds to the list of features.
- The difference between the 694 vs. 675 is that the latter doesn’t tag along with any Virtual Walls device.
- Also, the 675 doesn’t have the extra filter which is supplied with the 690.
- The last difference is regarding aesthetics. The 690 has been finished in black/silver while the 675 is black.
But in terms of cleaning performance, there is no difference whatsoever. Both models deliver 600pa, have a dual multisurface brush and high-efficiency filters. The runtime is 60 minutes, while the navigation is the random iAdapt 1.0.
2. IRobot E Series (Roomba E5 vs. E6)
The Roomba E5 was released in 2018 September together with the Roomba i7. Later on, came the Roomba E6. To start, there is no significant difference between Roomba E5 vs. E6, at least in terms of features and performance.
The iRobot E5 is the standard model and is available in most retail shops, online and offline.
On the other hand, the E6 is available at select retail shops. The main difference between the two is the accessories included. The Roomba E5 doesn’t come with any containment devices, but it is compatible with Virtual Walls technology.
Also, the E6 comes with an extra filter for your first replacement, while the E5 comes with only one installed.
There’s also a difference in aesthetics with the Roomba E5 finished in all black and the E6 in two tones; black and tan. Now, regarding the price, the E6 is more expensive as it tags along with two Dual Mode Virtual Walls barriers.
When it comes to cleaning performance, the Roomba E5 and E6 are the same. They feature 1000pa suction power, a dual multisurface brush roll, and HEPA style filters.
We recommend these models for homes with bare floors and low pile carpets.
Regarding cleaning time, the E5 can run for 90 minutes, which is impressive now that the likes of the 890 and Roomba i7 do 75 minutes.
Unfortunately, the navigation system is still wanting. The Roomba E5 will still hit a few obstacles in high traffic rooms.
Also, it doesn’t clean using a systematic approach. The random movement, on the other hand, makes cleaning slower, and chances are high, some spots in large apartments won’t be touched.
3. Roomba I Series (Roomba i7 vs. i7+)
The I series was introduced late in 20i8 and came to replace the 980, but it was an effort in futility until the 980 was retired.
The i7 (7150) and i7+ (7550) came with several downgrades, the most noteworthy being the suction power and runtime. The iRobot I series has a 75 minutes runtime while the 980 has a cool 120 minutes runtime, but it does resume cleaning after recharging.
Another shortcoming is the average suction power. Roomba excelled in terms of suction power, delivering 1670pa when Carpet Boost is activated. The i7 delivers a paltry 1000pa, and that’s the reason it is not a good choice for high pile carpets.
Despite the shortcomings, the i7 is still a worthy Roomba. It was the first robot vacuum with self-emptying technology. This is a pretty new function that is enabled by a CleanBase unit, which is basically a large bin integrated with the charging dock. There’s also an opening under the Roomba where the unit connects to the CleanBase. Now, one thing, the only difference between Roomba i7vs i7+ is that the former doesn’t include a CleanBase unit, but it is compatible with the technology.
The i7 also debuted iAdapt 3.0 navigation, Roomba’s latest navigation technology. It’s not much different compared to iAdapt 2.0 with Imprint Smart Mapping as the only addition. The sensors and the realtime camera is maintained, but with Imprint Smart Mapping, the Roomba learns and adapts to your home. Among the most practical features is Zone Cleaning, which allows homeowners to select specific rooms for cleaning.
4. iRobot S Series (Roomba S9 vs. S9+)
Released in 2019, the Roomba S Series is the latest robot vacuum from iRobot. It has perfected the flaws in the Roomba i7, and finally, we have a perfect replacement for the discontinued Roomba 980.
Much of the premium features the i7 boasts are intact. These include the self-emptying bin technology for the ceiling model. There’s also iAdapt 3.0, meaning the S9 is just as good as the i7 in large apartments with multi rooms, as well as homes with more than one floor.
Regarding suction power, iRobot integrated the latest Gen motor that delivers 2200pa, making the Roomba S9 the most potent robot vacuum we have tested so far. It’s even better than Roborock S5 and S6, which deliver 2000pa. With the Roomba 980 discontinued, this is the best Roomba for carpets at the moment.
This vacuum also has improved battery performance. It tags along with a 3300mAhmAh battery that can do 120 minutes in normal mode and 88 when Max mode is activated.
Unfortunately, it doesn’t have intelligent charging as of yet, so when it goes to the charging dock, it must charge for the entire period. Some models like Neato BotVac D7 will calculate the remaining cleaning time and recharge the exact power it needs to finish the job. Maybe this is a feature we’ll see in one of the Roomba wireless updates.
The Roomba S9 is the most expensive robot vacuum we have tested to date. The S9 (9550) is the base model, and just like the i7, it doesn’t come with the Clean Base Unit.
Shark Robot Vacuums
Shark vacuums are not as many as Roombas. Below are all the models on the market.
1.Shark ION RV700 Unavailable Choice
This was the first robot vacuum cleaner Shark ION released.
It was discontinued but then, did its part is setting up the footing for Shark ION in this volatile and unpredictable market.
This robot vacuum boasts the standard features you’d expect in a robot vacuum.
Aesthetically, it just looks like the average Roombas, but one striking detail is the thin design.
It stands at 2.6-inches only whereas Roombas are 3.6-inches.
This robot vacuum comes with remote control, and even though it doesn’t support Wi-Fi, it is a decent deal considering its affordable price.
Unfortunately, it was discontinued, and you may not find it in most retail outlets; both offline and online.
2.Shark ION RV720 Robot Dual-Action Robot Vacuum Cleaner
This is the model that replaced the Shark ION 700. However, there is so much resemblance between the two vacuum cleaners.
This one is also slim and retains the same interface like the one in the old robot vacuum. The finish is slightly different though.
One advantage of the Shark ION 720 is that it comes with an extra filter and two additional side brushes for your first replacement.
The Hair Detangling feature, you shouldn’t worry about the long hairs that are fond of jamming robot vacuums.
3.Shark ION RV750 Robot Vacuum WIFI-Connected and Voice Control
This is the prime Shark ION robot vacuum cleaner.
This is the prime Shark ION robot vacuum cleaner. One of the most notable additions is the Wi-Fi and voice control compatibility. You can now control the Shark ION right from your Smartphone or connect it with Alexa and Google Assistant.
At least the Shark ION 750 puts the brand on the map now that everyone is looking for Smart robot vacuums. As far as convenience is concerned, the Shark ION R75 is a great deal for the money.
Regarding performance, we don’t have so much improvement from the earlier model. The RV750 still puts up the same suction power as the R72 and employs a 3-stage cleaning system. The runtime is still 60 minutes, and so is the SLAM navigation that cleans randomly.
The RV76 is a pretty new model that is available at select retailers. There is no much difference between the RV75 vs. RV76 save for aesthetics and availability. The Shark R761 is finished in black and navy blue while the R75 is black and grey with gold stripes.
4. Shark RV800 Series (Shark R85 vs. R87)
The Shark R85 is the base model in this series. It makes a leap from the average performance the R75 put forward.
One of the improvements is the enhanced motor that promises 3* the air power in the predecessors, the R85.
It delivers a cool 1400pa when the high-power mode is activated. That makes the vacuum ideal for bare floors, as well as low-pile to medium pile carpets.
As for pet hairs, the R85 can pick up both the short and long pet hairs and tags along with a larger 0.6L bin.
The navigation is a step ahead of the R72. Dubbed Smart Mavi 2.0, the RV800 series relies on a set of sensors for navigation as well as floor mapping and scanning.
The runtime is still 60 minutes, and there is no resume function after the automatic recharging.
5. Shark ION R87
You must have also heard about the Shark ION R87, and this a combo of the R85 and Shark ION W1. The W1 is a handheld cordless vacuum cleaner.
This is precisely what we have also seen with the ECOVACS Deebot R98, which combines the Deebot R95 and a handheld cordless vacuum.
The docking station has been redesigned to accommodate the handheld vacuum, which has a multi-surface pet tool, crevice tool, and soft dusting brush.
6. Shark ION R100
The Shark RV1000, dubbed Shark ION IQ, is an intelligent robot vacuum that brings on board smart navigation and floor mapping system.
If you have high traffic rooms, and expansive apartments with more than one floor, this is a great deal.
It can learn and adapt to the floor plan of your home, and more so, the R100 can save up to three maps. The cleaning is methodical, so you won’t find any spots untouched.
Unfortunately, Shark RV1000 doesn’t have digital boundaries. You will have to put up with the bulky magnetic strips (8-foot strip is supplied).
Another shortcoming is regarding the runtime. While 90 minutes is an upgrade from the previous Shark robot vacuums, there is still room for improvement.
But we are glad that now, this vacuum can resume cleaning after recharging. The industry leaders boast up to 200 minutes runtime.
7. Shark ION R101AE
This is the latest, and of course, the best Shark robot vacuum in the market. It owes much of its features to the previous model, the R100.
But then, this model brushes shoulders with industry-leading robot vacuums with self-emptying technology.
Just like the Roomba i7 and S9, the Shark RV1001AE comes with a dock that integrates a larger bin.
Whenever the vacuum docks, the bin contents are emptied into the larger bin, which can hold the entire month’s dirt.
When it comes to cleaning performance, there’s nothing different the R101AE offers except for the fact that it is ideal for busy homes courtesy of the self-emptying bin.
Otherwise, it cleans bare floors and low to medium carpets exceptionally. This is the same case for pet hair – both long and short pet hair.
Shark ION 720 vs. 750 vs. Roomba 690/675
If you look at it from the budget perspective, the Roomba 600 Series matches the prices of Shark ION.
But is this the same case with performance and features? That’s what we are about to find just now.
If you look at it from the budget perspective, the Roomba 600 Series matches the prices of Shark ION.
1. Design: Shark ION 720 vs. 750 vs. Roomba 690
When it comes to the design of a robot vacuum, the most important thing is the height.
The winner here is Shark ION, but find out how they compare.
Roomba 690/675
This robot vacuum is round and boasts quite a sleek and stylish design. It has a diameter of 13.6-inches, and just like all Roombas, it stands at 3.6-inches high. Regarding weight, we measured it on our scale, and it hit 7.8 lbs.
Shark ION 720
This robot owes much of its aesthetics to the Roombas. However, it is much slimmer than Roombas standing at only 2.6-inches. The Shark ION has a 12.6-inch diameter and weighs 5.51 lbs. when the bin is empty.
Shark ION 750
Nothing much changed in the new Shark ION 750. It is precisely the same as the predecessor, with the three buttons on the interface. The only thing that has changed is the finish with the RV750 finished in a darker accent.
verdictWinner – Shark ION wins the battle here as it comes with a more low profile design. It is thinner than Roomba and also has a smaller diameter meaning it will go through tighter spaces.
2. Performance: Shark ION 720 vs. 750 vs. Roomba 690
One of the reasons Roombas have succeed is their versatility. Roomba 600 series is great for hardwood floors, tile, thin carpets, and allergens.
That’s what the manufacturer recommends it for. The truth of the matter is that it doesn’t do well on carpets and pet hair, but on hard floors, it’s excellent!
Here is how the Roomba 675 and 690 compare to Shark ION 720 and 750.
Priority
Roomba 690
One of the reasons Roombas have succeed is their versatility. Roomba 600 series is great for hardwood floors, tile, thin carpets, and allergens.
That’s what the manufacturer recommends it for. The truth of the matter is that it doesn’t do well on carpets and pet hair, but on hard floors, it’s excellent!
Shark ION 720
This robot vacuum cleaner is proposed for hard floors including hardwood, carpets as well as allergens. But the truth of the matter is that it’s quite similar to Roomba 694 in that it doesn’t do well on carpets.
However, when it comes to the pickup of allergens, it is an excellent choice!
Shark ION 750
Nothing new here; it’s recommended for hard floors, carpets and pet hair but on carpets, it doesn’t impress at all considering it is the top of the range SharkNinja robot vacuum that competes with the likes of Roomba 980.
I expected it to come with a dedicated mode for carpets, but it doesn’t have one.
verdictWinner – I really like Roomba 690 because of the raw power, but I am more inclined to Shark ION 720 because it’s cheaper and offers the same utility as Roomba 690 and RV750.
Suction
Roomba 690 & 675
These are entry-level robot vacuums that use quite old motors, probably a 1st Generation motor. The Roomba 690 and 675 deliver an average of 600 Pa, which is not very great for carpet cleaning.
Shark ION 720
I am afraid the Shark ION 720 doesn’t offer anything better than the Roomba 690. It also delivers suction power in the same range; 550 Pa which is negligibly higher than Roomba 690.
Shark ION 750
The same applies for the Shark ION 750 which I expected to have a powerful motor, like the top of the range models from iRobot and Neato, the Roomba 980 and D7 Connected.
verdictWinner – I would go for Roomba 675 or 690 because of the slightly higher suction power. However, that is not to say that they impress when it comes to vacuum power; they are all below my expectations.
Brush
Roomba 690 & 675
This entry-level robot vacuum cleaner has a dual multi-surface brush system. It does a great job on hardwood and carpets, but the problem is that it gets tangled way too often. Regarding side brushes, Roomba has two on either side and is also supplied with an extra pair.
Shark ION 720
This model comes with a self-cleaning brushroll which greatly reduces tangling and maintenance requirements. On either side, we have sweeping side brushes that clean the path of the vacuum. Also here, two extra side brushes have been included for the first replacement.
Shark ION 750
Here, the brush system borrows much from the older Shark ION only that in this case, we have helix-pattern high-tensile bristles that enhance dirt pick up on both hard floors and carpets. The detangling technology is also available, but there are no extra side brushes.
verdictWinner – Shark ION is the winner here. I would go for a Shark ION anytime, especially if I had long-haired dog breeds because of the detangling technology. Roomba 690 has a regular brush that gets tangled very often.
Filter
Roomba 690/675
This is indeed an old model, and again here, it uses the old Aerovac filtration system that has HEPA style filters. Though they are efficient, they are not as good as true HEPA filters.
This is indeed an old model, and again here, it uses the old Aerovac filtration system that has HEPA style filters. Though they are efficient, they are not as good as true HEPA filters.
Shark ION 720
The Roomba 690 suffers defeat here because SharkNinja built the RV720 with true-HEPA filters. These have a 99.97% efficiency making them best for allergy sufferers.
Shark ION 750
Obviously, the latest model in the SharkNinja robot vacuum line will have true HEPA filters. If you have pets, you understand the problem of dander; that’s exactly what HEPA filters capture.
verdictWinner – Definitely, Roomba 690/675 is not a favorite because it has HEPA-style filters, which are not the original HEPA filters as we know them. Shark ION 750/720 have HEPA filters making their air filtration more efficient.
Extras
Roomba 690/675
It comes with Dirt Detect Series I. This is a feature that uses acoustic sensors to detect where there is dirt concentration. It goes to the area and switches to Spot mode.
It comes with Dirt Detect Series I.
This is a feature that uses acoustic sensors to detect where there is dirt concentration. It goes to the area and switches to Spot mode.
Shark ION 720
Perhaps the unique aspect of Shark ION is the detangling technology.
It is a self-maintenance feature that cleans the brush roll removing any tangled material.
Shark ION 750
Detangling technology is also the only extra feature Shark ION RV750 offers.
I’m also disappointed because it ought to have done better as Shark ION’s best model.
verdictWinnerIt is very hard to call a winner, but there are areas where each brand wins.
Shark ION 720/750 is a great option if you have long-haired dog breeds like Chihuahua.
On the other hand, the Roomba 690’s Dirt Detect technology is also irresistible.
3. Battery: Shark ION 720 vs. 750 vs. Roomba 690/675
As you are all aware, robot vacuums have rechargeable batteries. There are several areas that you need to have an in-depth discussion on clearly.
These include; the battery type, technology, capacity, and runtime. Also, the power management options are essential.
Roomba 690/675
This vacuum comes with a 1800mAh Li-ion battery. It can run for 90 minutes which is pretty enough to finish cleaning an average apartment. It will recharge automatically but won’t resume cleaning.
Shark ION 720
Also here, you get a Li-ion battery with 1800mAh capacity which is also a considerable runtime. The Shark ION 7209 can also run for an hour before going back to the charging base.
Shark ION 750
The crème model from Shark ION also has an 1800 mAh battery and will also run for an hour and won’t resume cleaning after recharging. I can’t complain much considering the price.
verdictWinner – This is hard to call, but I would say the Roomba 690 is the winner when you look at the battery life cycle. Roomba batteries last for around 24 months compared to Shark ION that does an average of 18 months.
4. Navigation: Shark ION 720 vs. 750 vs. Roomba 690/675
This is another crucial talking point when choosing a robot vacuum cleaner. There are several important aspects that you need to look at including technology, mapping, and boundary marking.
Navigation and mapping
Roomba 690/675
iRobot uses iAdapt 1.0 navigation technology as well as a host of obstacle sensors and cliff sensors. Regarding floor mapping, it doesn’t have a methodical pattern, so it cleans randomly.
Shark ION 720
This robot vacuum uses Smart sensors backed up by the regular obstacle and cliff detection sensors. The Shark ION 720 too uses a random cleaning pattern and takes longer to complete.
Shark ION 750
It also uses the same navigation technology as the predecessor, but at least its software is updated. RV750 is also
verdictWinner – Roomba’s iAdapt 1.0 is more accurate and does well in high traffic rooms more than Shark ION.
But that is not to say that it is the best Roomba for high-traffic rooms.
Boundary marking
Roomba 690 vs. 675
It comes with Virtual Walls technology that uses infrared sensors to mark limits. They are easy to set up because you only need to align the nodes. But the Roomba 675 doesn’t include any Virtual Walls devices.
Shark ION 720
This model comes with boundary marking technology too; BotBoundary™ Strips. Here, instead of the infrared sensors, we have physical markers.
Shark ION 750
The boundary marking technology is not updated in the new Shark ION RV750. We feel this is such a letdown for the best Shark ION robot vacuum cleaner.
verdictWinner – It’s obvious that Roomba 690 is the best regarding boundary marking. It is easier to set up, but on the downside, Roomba 690 included only one node, and an extra pair costs about $45.
5. Smart features and convenience: Shark ION 720 vs. 750 vs. Roomba 690
Robots are smart and intelligent, but the degree greatly varies. Let’s see what Shark ION offers against its counterpart the Roomba. Here, we are going to look at factors like scheduling, remote control, reports and so on.
Remote operation
Roomba 690/675
If you did your homework, you understand that this is the upgrade of the Roomba 650 and the new extras include Wi-Fi and voice control. That said, the Smartphone App and Alexa are the remote control options available.
Shark ION 720
This robot vacuum comes with a physical remote controller in place of Wi-Fi. You can do everything you’d wish to do on the Smartphone only that in this case, you can’t do it remotely; you need to be near the vacuum.
Shark ION 750
At least SharkNinja improved here by including Wi-Fi and voice compatibility in the RV750. This model can connect to your Smartphone for remote operation as well as voice control integrations like Alexa and Assistant.
verdictWinner – Here. I would go for Roomba 690 or 675 because the RV750 has Wi-Fi connectivity issues. Without strong Wi-Fi coverage, it keeps dropping the connection.
Scheduling
Roomba 690/675
This vacuum can be programmed to start cleaning at specific times throughout the week.
The advantage is that you can do it with ease remotely from your Smartphone.
Shark ION 720
The RV720, just like all robot vacuum cleaners can also be scheduled for the entire week.
But unfortunately, you need to be at home to schedule it from the remote controller.
Shark ION 750
Also the RV750 can be programmed to clean daily throughout the week, and like the Roomba 690 it comes with Wi-Fi.
You can schedule it from the Smartphone App remotely.
verdictWinner – Here, the Roomba 690, 675, and Shark ION 750 carry the day because of their convenience.
Yes, the RV720 can be programmed, too, but if you bring in usability, the Smart robots carry the day.
Shark ION 720 vs. 750 vs. Roomba E5/E6
Now, let’s get to the face-to-face comparison between Roomba E5 vs. Shark ION 750 vs. 720.
1. Design: Roomba E5 vs. Shark ION 720/750
Roomba E5
It stands at 3.6-inches high with a diameter of 13.6-inches and 8.5 lbs. weight. This is the same for the Roomba E6
Shark ION 720
This one is much smaller standing at 2.6-inches with a 12.6-inch diameter. It can fit under tight spaces and is easy to carry at 5.5 lbs.
Shark ION 750
This model maintains the same design and dimensions of the earlier model. The only difference is the fact that its color shade is a little bit darker.
verdictWinner – It’s with no doubt that Shark ION 720 and 750 win the contest here. The slim design allows them to go under most furniture.
2. Performance: Roomba E5/E6 vs. Shark ION 720/750
In our previous comparison of Shark ION 720/750 vs. Roomba 600 series, the Roomba 690/675 was outdone is several areas. But that’s understandable considering it is among the oldest Roombas we have in the market. Let’s see whether the Roomba 890 will bring home the points.
Priority
Roomba E5/E6
Unlike the Roomba 690, this one has improved action on carpets and allergens. This is courtesy of an upgraded motor and true HEPA filters.
That said, it is a better all-round cleaner, but certainly, not the very best!
Shark ION 720
This is just an average robot vacuum cleaner that would compete with the Roomba 690 but not the 890.
It is best for hardwood, tile and linoleum floors as well as allergens but not carpets, especially the heavy pile carpets.
Shark ION 750
Also here, there is nothing to smile about because even being the latest Shark ION robot vacuum, deep carpet cleaning is not guaranteed.
But, for hard floors and pet messes, this is a great vacuum cleaner for the price.
verdictWinner – Roomba E5 is undoubtedly the best choice here. While Shark ION may match Roomba’s performance on hard floors and pet messes, Roomba has a powerful motor for more vacuum power, something that makes it a better cleaner on carpets and thus a more versatile robot vacuum.
Suction
Roomba E5/E6
It uses a 2nd Gen motor that has been optimized to deliver 5* more vacuum power. On average, the Roomba E5 delivers 1000 Pa though it is noisy.
Shark ION 720
This robot uses quite an old motor, and even though it is quieter than Roomba 890, power is compromised. It produces an average of 550 Pa only.
Shark ION 750
Despite being the latest Shark ION vacuum, the RV750 has very low suction power. It still delivers 550 Pa just like RV720.
verdictWinner – Roomba E5 is the winner here because it has more suction power. This explains why Roomba E5 and E6 are better robot vacuums for carpets than Shark ION. Remember, the higher the vacuum power on carpets, the deeper the clean.
Brush
Roomba E5/E6
Tangling was a problem in the old Roomba 690 but not anymore with the Roomba E series. This model comes with a tangle-free dual multi-surface extractor. There is also a pair of side brushes for sweeping the sides of the vacuum.
Shark ION 720
This model comes with the old brush roll that does quite a good job on hard floors and carpets. It picks all kinds of dirt; from dust to pet hair. On the sides, there are also two side brushes for sweeping the paths.
Shark ION 750
The latest Shark boasts a newly designed helix-pattern high-tensile bristles brushroll. It’s able to pick all kinds of dirt from small dirt to allergens despite the surface. It’s also assisted by two side brushes.
verdictWinner – Here, it is hard to call, but I think the Shark ION has the edge. The Detangling technology makes life easier because in the event it gets tangled, it doesn’t make jam, it solves the problem autonomously.
On the other hand, the Roomba’s extractors are not invincible, and in case they tangle, you have to come to rescue it!
Filter
Roomba E5/E6
Here, iRobot upgraded to , which uses HEPA-style filters. These are more efficient compared to Aerovac filters.
Shark ION 720
True HEPA filters have also been used to design the RV720 so you can be sure that all allergens are filtered leaving you with fresh, breathable air.
Shark ION 750
Like the predecessor, RV750 also have true HEPA filters for 99.97 efficiency in capturing all allergy triggers and bad odor.
verdictWinner – If you suffer from nasal allergies, any of the Shark robot vacuum cleaners is up for the task.
Extras
Roomba E5
If you remember, Roomba 690 had Dirt Detect Series I. The E5 and E6 come with Dirt Detect Series II. They also have full bin indicators, features Shark ION vacuums lack.
Shark ION 720
The unique feature Shark ION 720 offers is Detangle technology. Otherwise, if you don’t have pets or you have no worries about tangling, nothing else is offered.
Shark ION 750
This vacuum also offers Detangling technology only as the only extra. If you have pets, this is something that should interest you.
verdictWinner – The Roomba E5/E6 is the best choice here because of the Dirt Detect Series II feature.
While Shark ION stood a chance against Roomba 690 here, the two vacuums are no match for Roomba E5 because Roomba now has a tangle-free brush system, so the Detangling technology is not an advantage for Shark ION.
3. Battery: Roomba E5/E6 vs. Shark ION 720/750
In the last face-to-face comparison, Shark ION also competed favorably with Roomba 690 primarily because they have the same runtime. But is this case for the Roomba E series also?
Roomba E5/E6
This model comes with a much powerful battery but will do 90 minutes on average. Recharge time is almost two hours, and the Roomba goes to the Home base alone but won’t resume cleaning.
Shark ION 720
This vacuum runs for an average of 60 minutes, just like Roomba 890. It also has almost the same recharge time and will dock automatically. However, there is no resumption after that.
Shark ION 750
Nothing new in this model save for the slightly higher runtime of around 70 minutes when it’s new, but after some time, it drops back to 60 minutes. It also self-recharges but has no auto-resumption.
verdictWinner – I would go for the Roomba E series because of the longer life cycle. Roomba batteries are the industry’s best when it comes to the lifecycle.
4. Navigation: Roomba E5 vs. Shark ION 720/750
If you have a large apartment with high-traffic rooms, then the navigation should be a major concern when shopping.
So what are the most important aspects to be considered?
Navigation and mapping
Roomba E5/E6
It still uses the old iAdapt 1.0 navigation system backed up by obstacle detection and cliff sensors. Regarding floor mapping, it is not wholly methodical, but at least it moves in a pattern.
Shark ION 720
This one uses Smart sensors to find its way wound your house assisted by obstacle and cliff sensors as well. Cleaning is very random and will often miss some sports if you have a large floor.
Shark ION 750
Nothing changes here again, and it’s such a letdown for the latest Shark ION to have such an old navigation technology. The movement is random, and besides missing some spots, it takes longer to clean.
verdictWinner – Roomba E series carries the day here because it at least moves in a methodical pattern and cleans faster. However, if you want the best Roomba for high-traffic rooms, the Roomba S9 and i7 are the beasts.
5. Smart features and convenience: Roomba E5 vs. Shark ION 720/750
The advantage of robot vacuum cleaners is that they offer Smart connectivity and convenience. So, how does the Roomba E series compare to Shark ION 720 and Shark ION 750?
Remote operation
Roomba E5
This vacuum cleaner comes with Wi-Fi for remote Smartphone operation. It also supports Alexa and Assistant as well as several other 3rd party integrations.
Shark ION 720
Here, there is no Wi-Fi; instead, you are supplied with a physical remote control. That means you can’t control the robot vacuum with the Smartphone App or Alexa.
Shark ION 750
This is the only Shark ION robot vacuum with Wi-Fi. That means you can control it from the Smartphone App or use Alexa. The only problem is the many connectivity issues.
verdictWinner – Roomba E5 is the winner here because it comes with Wi-Fi compatibility and supports Alexa. Shark ION 750 doesn’t make it to the top because of Wi-Fi connectivity issues.
Scheduling
Roomba E5/E6
This robot vacuum cleaner can be scheduled for seven days running. The advantage here is that you can program it easily on the Smartphone App.
Shark ION 720
This model also offers Schedule cleaning for a week. The only worry is that you have to program it from the remote controller, so you have to be home.
Shark ION 750
At least with this model, just like Roomba 890, you can program it for 7 days as well, but this time you get the convenience of Smartphone operation.
verdictWinner – Were it not for the connectivity issues, I would go for the cheaper Shark ION 750, but considering the many complaints, we have settled for the Roomba E series.
Shark R85 vs. R100/101AE vs. Roomba i7 vs. S9
Now, this is the ultimate test where we have put the best Shark vacuums against the best from their counterparts, iRobot.
1. Design, aesthetics and dimensions
Here, there are three aspects to consider; shape, aesthetics, and dimensions/weight. The shape determines how the robot covers the walls and edges, while the dimensions has got a lot to do with where the cleaner can reach.
Shark R85
This is a round-shaped vacuum cleaner finished in black with white stripes. Regarding the dimensions and weight, the RV850 has a 12.5-inches and weighs just 5.5 lbs.
Shark R100/101AE
The RV1000 series is also round-shaped and thin, as well. When it comes to aesthetics, the R101 is finished in pure black, same as R100.
Roomba i7
The is vacuum is round-shaped as well. It measures 13.6-inches in diameter, is 3.6-inches high, and weighs 7.44lbs. As for the finish, it is black with some grey accents.
Roomba S9
This is the first Roomba to adopt a D-shape design, just like Neato Botvac robot vacuums. Regarding the dimensions, it measures 12.9-inches inches in diameter and weighs. The finish is black on bronze.
2. Cleaning Performance
Which is the best vacuum in terms of cleaning performance? Let’s find out.
Robot vacuums offer varying performance. Here, we consider aspects like cleaning orientation and the specialization of each component.
Shark R85
This is a dedicated robot vacuum designed for bare floors and pet hair. While the company fronts it for carpet vacuuming, it gets overwhelmed on the high pile carpets and rugs.
Shark R100/101AE
The Shark RV1000 series is designed for bare floors and pet hair, just like the R85. The duo also performs well on all types of carpets.
Roomba i7
This vacuum is recommended for bare floors and both long and short pet hair. Unfortunately, the performance on medium to high pile carpets is not good.
Roomba S9
The S9 is an all-round vacuum that can handle bare floors and all types of carpets including the area rugs and flokati.
Suction Power
Shark R85
We are glad the RV850 has improved suction compared to the R75. It delivers an average of 1400pa when at its best.
Shark R100/101AE
The RV1000 has improved suction. It delivers a cool 23cfm making it a great deal for low to medium pile carpets. But still, on high pile carpet, it will struggle a bit.
Roomba i7
The Roomba i7, despite being a new model, doesn’t impress here as it delivers just 1000pa. That’s the reason we don’t recommend it for high pile carpet vacuuming.
Roomba S9
The S9 has improved suction power drastically. It can deliver a whopping 2200pa making it the most potent vacuum we have reviewed so far. It is the best choice for carpets and stubborn dirt.
Brush System
Shark R85
The R850 uses a spinning and self-cleaning brushroll to agitate and pick up debris and pet hair. There are also two side sweeping brushes.
Shark R100/101AE
The two new Shark vacuums also have a self-cleaning brushroll alongside two side sweeping brushes.
Roomba i7
The i7 and i7+ have an enhanced dual multisurface brush system. The first one is for agitation and the second one for picking up dirt. There’s also a side sweeping brush.
Roomba S9
The S9 uses the same dual multisurface brush system and a side sweeping brush. It also maintains the anti-tangle technology so you won’t have to worry about the long pet hair jamming it.
Filtration
Under filtration, there are two important things to consider; the type of filters used and the bin.
Shark R85
This vacuum has a much larger bin compared to the R75. This is a 0.6L bin that has to be emptied manually when full. When it comes to filtration, we are glad Shark vacuums use true HEPA filters, which are 99% efficient and filter down to 0.3 microns.
Shark R100/101AE
The Shark R100 comes with the same 0.6L bin, which also needs manual emptying. However, the R101AE comes with the same 0.6L bin, but this time, there is a self-emptying bin mechanism, so you won’t have to be emptying it manually. The filtration is the same as that of the R85.
Roomba i7
The Roomba i7 brings on board a 0.3L bin and has a full bin indicator though it is not a necessary feature now that there’s also a self-emptying bin system. It can hold up to 30 bags of dirt, which is equivalent to a whole month’s dirt. The filtration uses a HEPA style filter.
Roomba S9
The S9 is not different from the i7 in any way. It also tags along with a 0.3L bin, full bin indicator, and HEPA style filters. It’s unfortunate that being the latest Roomba, there are no true HEPA filters.
3. Battery and runtime
A good robot vacuum should have a high capacity battery to make sure that it cleans the entire house on a single charge. Let’s see how these four vacuums compare.
Shark R85
The Shark R85 and R87 use a 2550 mAh battery that can last for just 60 minutes. Unfortunately, it will not resume cleaning automatically, but the recharge is automatic.
Shark R101/R100
The Shark R101 has improved runtime courtesy of a larger battery that can power it for 90 minutes when in normal mode and 50 minutes when running in high power mode. The recharge is automatic, and so is the resume.
Roomba i7
The Roomba i7 boasts a 1800mAh battery that has been optimized to offer 75 minutes runtime. This is short for such a high-end vacuum, but we are glad it resumes cleaning automatically after recharging
Roomba S9
The S9 has an improved runtime courtesy of a larger 3300mAh battery that can put up a solid 120 minutes runtime in standard mode and 88 minutes in high-power mode. The recharge and resume functions are automatic.
4. Navigation, Mapping and Boundary Marking
While cleaning performance is important, you also have to consider the navigation technology, floor mapping system, and mode of containment.
Shark R85
This is a model that uses Smart Navi navigation system, which is a SLAM based algorithm for navigation. There are a bunch of obstacles sensors and retractable bumpers alongside anti cliff sensors.
When it comes to floor mapping, the R85 cleans in a semi-random pattern. As for containment, you get physical boundary markers.
Shark R101/R100
The RV1000 Series is dubbed the Shark IQ because of the intelligent navigation and floor mapping. No cameras have been incorporated, but the entire system has been revamped to offer intelligent floor mapping and scanning.
Now, Shark has a vacuum that can think, learn, and adapt to the floor plan of your home. Unfortunately, there are no digital boundaries. Instead, you’ll have to put up with the physical magnetic strips. Also, there are no fancy features like Zone Cleaning and Spot cleaning.
Roomba i7
The i7 came with a new navigation technology dubbed iAdapt 3.0. Besides the sensors, it has a real-time camera, and most importantly, it learns and adapts to your home’s layout courtesy of Imprint Smart Mapping.
The Roomba i7 also tags along with some exclusive features, including Zone Cleaning, which allows homeowners to choose the exact rooms they want the robot to vacuum instead of cleaning the entire house unnecessarily. As for boundary marking, the i7 boasts Virtual Walls.
Roomba S9
There’s nothing different with the Roomba S9 as it also comes with iAdapt 3.0. It uses a VSLAM algorithm in navigation, and while it can work with Virtual Walls, a digital boundary marking technology, Keep Out Zones is in the pipeline.
When it comes to floor mapping, the S9 also features Imprint Smart Mapping so it can learn and adapt to the plan of your house.
5. Smart features and convenience
Robot vacuums offer so much convenience, but this varies from one model to another. Here is a Shark vs. Roomba comparison from this frontier.
Shark R85
Shark R85 and R87 both have WiFi for mobile app operation, as well as updates.
The vacuum can also sync with voice assistants like Alexa and Google Assistant.
The R85 also has a scheduling function that allows for seven days of programmability.
Shark R101/R100
The Shark R100/101 also have WiFi and can be controlled via the mobile app or just using your voice if you have a smart speaker.
This vacuum can also be programmed for seven days straight.
Roomba i7
The i7 and i7+ are smart home ready robot vacuums.
The feature 2.4GHz WiFi for mobile operation on the iRobot Home App as well as Alexa and Google Assistant.
Roomba S9
The S9 is the latest vacuum cleaner from the California brand. It also features WiFi for remote operation and can be scheduled to clean at specific times for the entire week.
Roomba vs. Shark ION: What’s the best robot vacuum brand?
Roomba is the best robot vacuum brand in this discussion. Before I tell you the main reasons why I chose Roomba over Shark ION, here are two important takeaways.
One of the main reasons for Roombas success is specialization in floor cleaning solutions only. It has concentrated on a smaller niche, robot vacuum cleaners, something that has helped them curve a superior brand. But most importantly, it is their investment in R&D that has put the brand where it is today.
When it comes to Shark ION, I must say that I really admire their products including the SharkNinja juice extractor. However, as far as robot vacuums are concerned, it doesn’t impress me that much because they just offer alternatives to the options we already have. But good for them, they increased the product range.
Why Choose Roomba?
- 1.Better all-round cleaning – Roombas have the best cleaning features for a comprehensive cleaning. Carpet Boost is, in fact, the industry’s leading carpet cleaning technology.
- 2.Longer runtime – The best Shark ION robot vacuum runs for around 70 minutes when still new while Roomba 980 does an average of 120 minutes.
- 3.Recharge & auto resume – This is among Roomba’s biggest strongholds. The Roomba 960 and 980 will recharge and resume, but none of the Shark IONs offer this.
- 4.Better boundary marking – It’s pretty hard to set up the physical markers. Virtual Walls nodes are much easier to use though Neato’s No-Go Lines is the best regarding usability.
- 5.Superior navigation – Roombas have the latest VSLAM navigation meaning that they are best for high-traffic rooms and large apartments.
- 6.The extras – Roombas offers several extras like Dirt Detect, Clean Maps reports, Wireless Updates and so on. So far, there’s nothing unique about Shark IONs.
Why Choose Shark ION
- 1.Cheaper options – Shark ION robot vacuums are much cheaper and still offer quite some great performance.
- 2.Slimmer design – A good vacuum cleaner should be very slim, and that’s exactly what Shark IONs are. They stand 2.6-inches high while Roombas are 1 inch taller.
In as much as Shark ION robot vacuums may be cheaper, it is clever to look at it from a long-term expensive. The maintenance costs of Shark ION robots is also three times higher than that of Roomba.
