Roborock S4 vs. S5 vs. S5 Max vs. S6 vs. Xiaowa E25 vs. E35
You will agree with me, Roborock, though a Chinese brand is the ultimate robot vacuum for buyers on a budget.
It boasts the latest cutting edge technology, rivaling the likes of Roombas and Botvacs, yet the best model from the Xiaomi-backed company costs almost half the price of Roomba’s best model, the S9+.
Roborock is an independent brand that manufactures robot vacuums in the Roborock and Xiaowa series. It is the same company that manufactured the Xiaomi Mi vacuum, but at the time, it was under the tech conglomerate. Later on, Roborock parted ways with Xiaomi and released their first model, Roborock S5.
However, it’s important to note that Xiaomi still has shares in Roborock. Also, Roborock has fronted another line of robot vacuums: Xiaowa.
Roborock vs. Xiaowa, what’s the difference?
Well, the Xiaowa vacuums are a cheaper alternative to the Roborocks. Among the main differences is the navigation system. Xiaowa E25 and E35 come with motion tracking, which uses gyroscopes for navigation while Roborocks have a lidar system that uses a laser.
Xiaowa E25 vs. E35
The Roborock E20/E25 is a 2-in-1 cleaner that vacuums and mops simultaneously.
It boasts above-average suction power, an advanced brush system, and enhanced filtration. It’s also a smart robot vacuum, and the app hosts a range of convenience features.
If you are on a budget, the Xiaowa E20 or the E25 should top your wish list. It does a great job in small to medium-sized apartments with minimal traffic. Its pet hair pickup performance is also excellent, but unfortunately, the performance is not as good when it comes to the long dog hair. As far as mopping goes, the E25 is also an excellent choice, as long as you don’t have carpets.
We love the mix of features and affordability. The E25 stands out as the best cheap robot vacuum at the moment.
However, its runtime is shorter as the battery is half what other models have. Another shortcoming, the navigation is not very accurate in large apartments and high traffic rooms.
The cleaning performance is more or less the same, especially mopping. But then, there are a few things Xiaowa improved on in this model, and that’s the reason it costs a little bit more than the predecessor.
For those who have slightly larger apartments, this one can clean 150-200 sq meters while the E25 can manage a maximum of 150 sq meters.
It’s such a great deal to double the battery capacity of the E35. This is a 5,200mAh rechargeable battery that lasts a cool 150 minutes when in low power setting.
Other features like self recharge and resume are intact. When it comes to cleaning performance, there is a small boost in terms of suction power. The E35 delivers 2000pa while the E25 has a paltry 1800pa. Otherwise, all other features are standard.
Unfortunately, the E35 is not LIDAR based. It uses the same navigation technology as the E25 – it’s still a Motion Tracking system. That means you can’t rely on this vacuum in large apartments, with many rooms, and high traffic.
The navigation processor is also a standard one – remember the high-end models use a 32-bit quad-core CPU. This model also lacks Zone Cleaning, a feature proving to be very resourceful.
Roborock S4 vs. S5 vs. S5 Max vs. S6 vs. S6 Pure
Now, on to the higher models, the Roborock S4 vs. S5 vs. S5 Max vs. S6 vs. S6 Pure, which is the best choice?
The Roborock S4, available in black only, showed some great performance when it came to carpet vacuuming.
The robot boasts a 32-bit CPU so you can trust it, together with LIDAR, when it comes to vacuuming large apartments and high traffic rooms.
Now that it lacks mopping function, the S4 is a great deal for carpets considering how the S5 and S6 misbehave.
The two are not quite intelligent and would make your carpet wet from time to time. The S4, with a maximum of 2000pa, therefore, stands out, not unless you buy the S5 Max, which discerns bare floors from carpets.
In terms of cleaning performance, the Roborock S4 is a great purchase, though not as versatile as its peers which offer 2-in-1 cleaning. It also lacks when it comes to several smart and convenience features, for example, Room Select, which the Roborock S5 lacks.
If you are looking for the cheapest Roborock with mop, this is your match. We are glad the suction power, brush, filtration system, and mopping function are all up to the mark.
The S5 may be an old vacuum now that we have the S5 Max, S6, and the S6 Pure, but it’s still a force to reckon. The robot does a great job on apartments with bare floors. It vacuums and wipes all the stains and grime, be it from pet urine stains, or the paw marks your dog leaves behind.
But for the busy homes with multiple rooms and different cleaning needs, I’m afraid; it doesn’t have versatile customization options like high-end Roborocks.
Unfortunately, the Roborock S5 doesn’t come with all the smart features. One of the best features it lacks is Room Select. This vacuum doesn’t have a map learning function, so you can’t name the different rooms.
Another shortcoming, the S5 will try to mop carpets. Last, this vacuum uses the standard processor, meaning it is less efficient compared to the S4, S5 Max, and the S6.
Overall, it is a better vacuum for homes with pets, but for apartments with a mix of bare floors, and carpets or area rugs, it’s still a disappointment.
The first talking point of the S6 is the new 32 bit Quad-Core CPU, which makes everything faster. The company affirms that the new 32 bit processors yield 20% more efficiency, and this is something we confirmed from our cleaning cycle tests.
The brushroll also has more dense bristles that agitate dirt effectively and reduce tangling. Room Cleaning is also a great feature as the S6 knows where the kitchen is, and where the bedrooms are. This way, you can customize your cleaning.
On the downside, the Roborock S6 still tries to mop the area rugs and carpets, and this is such a nuisance. But because this model saves maps, it is a worthy purchase. It runs down the dirt on carpets, and mops stains and grime on carpets.
This vacuum is ideal for small to large apartments with a mix of carpets and bare floors. It picks up all kinds of dirt and wipes out the stains and grime exceptionally.
The S5 Max comes with a larger water tank at the expense of the dust bin. It has a 0.29L capacity, which is twice what the S5 and S6 have.
In addition to the larger water tank, the S5 Max has an electronic water tank system that ensures efficient water usage. You can control the water seepage right from the mobile app. Above all, some settings allow you to mark the carpeted areas – No Mop Areas.
On the downside, the Roborock S5 Max is quite expensive, but considering its performance, it is worth every penny.
Roborock Face to Face Vacuum Comparison
In this section, we have compared the above robot vacuums to find out what are the similarities, and where they differ.
1. Design and Aesthetics
When shopping for a robot vacuum, the design and aesthetics do matter. Make sure you understand the profile of each Roborock, and most importantly, learn to distinguish them by the aesthetics, and colors.
- The Xiaowa E2 is available in two colors. There’s the Xiaowa E20, a white variant, and Xiaowa E25, which is dark grey. As for the dimensions, the two are similar. Weighing 7lbs, they stand at 3.6-inches, and have a 13.8-inch diameter. This one has a small turret at one end of the top interface, and three buttons.
- The Roborock S4 is available in a single color, gloss black. At the top is a small turret that houses the LIDAR system, and three buttons for control. These are Power on/off, Start/pause, and home buttons. When it comes to dimensions, the robot stands at 3.5-inches, has a 13.8-inch diameter, and weighs 8lbs.
- The Roborock S5 is available in three colors. There is the black model (S50), while model (S50, black model (S55), rose gold color (S51), and an Inter Milan themed blue model, (S52). As for the dimensions, the Roborock S5 measures 13.78-inches in diameter and stands at 3.56-inches. As for the weight, the Roborock S5 is just 7.75lbs, making it one of the lightest robot vacuums we have tested. At the center of the top interface, there is a large turret, accompanied by two buttons.
- Next is Roborock S5 Max, and this one has been supplied in black only. As for the dimensions, it’s quite similar to the S5 in terms of dimensions, but as for weight, this one is negligibly lighter at 7.72lbs. Roborock S5 Max also has a large turret at the center, and two buttons.
- The S6 is in black and white and measures the same as the S5 Max, only that this one weighs 7.94lbs. So far, we have seen the S6 Pure in white. It’s more likely that there will also be a black variant, and probably a rose gold one.
2. Cleaning Performance
Just how do the Roborock vacuums clean? There are a lot of factors to discuss here.
All the Roborock and Xiaowa vacuums are robot vacuums with mops, and thus offer 2-in-1 cleaning.
There’s only one exception, Roborock S4, which doesn’t have a mopping function – it’s a dedicated robot vacuum. This is one of the areas Roborock has beaten California-based bigwigs Roomba is the cleaning orientation. No Roomba offers 2-in-1 cleaning; you have to buy a separate robot mop, in this case, a Braava.
All the Roborock vacuums that have mopping function share the same mopping mechanism. They feature washable microfiber mopping pads that attach under the robot. A water tank supplies water to the cloth during wet mopping, but homeowners can also choose dry mopping.
The main difference here is the new Roborock S5 Max, which comes with a larger 0.29L water tank compared to the S5, and S6 which have a 0.14L water tanks. This is the same as the Xiaowas, which share the same 0.14L water tanks. The new Roborock S6 Pure is also impressive with a 0.18L water tank.
Above all, the S5 Max has virtual no-mop zones meaning it won’t be mopping carpets, like the S5 and S6. Also worth mentioning is precision water control right from the app.
How powerful are Roborock vacuums? This is an important consideration when choosing any vacuum, Roborocks are no exception. Compared to other brands, talk of ECOVACS, iLIFE, and Neato, Roborock. The entry-level Xiaowa E25 boasts an incredible 1800pa in high power mode.
All the other vacuums are rated 2000pa. This is according to the specifications on the manufacturer’s website. However, the Roborock S4 showed more potential while the S6 didn’t perform that well – there is a slight dip in suction power.
When it comes to operation noise, the vacuums averages 65 – 70 decibels in low and high power mode.
But getting into the details with our Sound Meter Pro, we found the Roborock S6 and Xiaowa E2 to be exceptionally quiet, producing just 68db in Max mode, while the S4 was the loudest at 71db in the same mode.
Generally, this is quite impressive considering the vacuum power at the said levels.
The brushroll is a crucial component, especially when it comes to picking up stuck-on dirt, and pet hair. Also, on carpets, it’s an invaluable addition to the robot vacuum.
There are a few differences regarding the brushes of the older generation Roborocks (Xiaowa E25 and Roborock S4), and the new generation models (Xiaowa E35, S5, S5 Max, S6, S6 Pure).
First, the new generation side sweeping brush is more durable, and has been designed to sweep wall edges more efficiently.
Coming to the main brush, the new brushroll has more bristles, and is well adapted to picking up the long dog hairs, with minimal tangling. S for the spares, you can use the new generation brushroll on an old generation Roborock, and vice versa.
If you have pets or allergies, you need to mind about the filtration system.
The industry standard is HEPA grade filtration, which is 99.99% efficient and filters down to 0.3 microns.
Roborock and Xiaowa vacuums use a washable E11 air filter, which is HEPA-style filters, so they don’t guarantee the best air filtration. But we liked the multistage filters which trapped all the large allergens, talk of the pollen, and dust mites.
- When it comes to dustbin capacity, the S4 is the smallest with a 0.42L bin.
- Next are the S5 and S6, which come with 0.48L bins
- While the S5 Max has a much smaller 0.46L bin, of course, to pave the way for the larger water tank.
- For the newly announced Roborock S6 Pure, we also have a 0.46L bin.
To make sure readers get a glimpse of how these vacuums perform in a real household setting, we conducted thorough tests. We had the Xiaowa E2, E3, Roborock S5, S5 Max, and the S6. The S6 Pure is still not in the market, but we’ll surely review it once it lands.
As usual, we used the common dirt, including pet hair, kitty litter, sugar, flout, rice, cereal, and sticky messes. Below is a chart that shows how they all performed on our performance scale.
Battery and Runtime
One of the areas Roborock has excelled over the likes of Roomba and Neato, is the excellent runtime. Besides, power management is ahead of most robot vacuum brands.
- The Xiaowa E25 is a second to the rest of the other models with a 2600mAh battery. Definitely, its runtime is shorter, 100 minutes to be precise.
- As for the Xiaowa E35, S5, S4, S5 Max, S6, and S6 Pure have the same 5200mAh rechargeable batteries. We thoroughly tested these vacuums, and they all run for a cool 150 minutes when in low power setting. As the power mode is stepped up, the runtime reduces.
- However, the Roborock S6 was different as it put up 180 minutes in the lowest power setting. Of course, it comes with a 5200mAh battery, but the optimizations allow it to offer an extra 30 minutes, which is quite some considerable time. For homeowners with large apartments, the S6 should be a priority.
When it comes to power management, we didn’t find anything different. All these vacuums will recharge and resume automatically after recharging. The recharge time is around 240 minutes.
One thing we liked is the intelligent charging feature. The vacuum can get some quick charge courtesy of Top-Up Charging to complete the job, instead of waiting for the entire four hours.
4. Navigation and Mapping
One of the major leaps in the world of robot vacuums is the navigation and mapping systems. This is also one of the areas where Xiaowa and Roborock vacuums differ.
When it comes to navigation, the two Xiaowa vacuums use an optical tracking motion sensor to find their way around your house. The notably lack the large turret we see in Roborock vacuums. While they do a good job of knowing where to pass, they are overshadowed by the new generation LIDAR navigation.
All the Roborock vacuums come with a LIDAR. Here, there is an invisible spinning laser that scans and maps your house, and using the SLAM algorithm; it has an idea of where the sofa is, the doorways, and other landmark features.
One thing to point out is the fact that the E25, E35, and S5 come with a standard CPU while the rest of the models boast an upgraded 32-bit Quad-core processor. The advantage of this new CPU is an improvement of 20% when it comes to efficiency.
When it comes to floor mapping, the Xiaowa E2 and E3 use a Z-shape cleaning approach. They move in straight lines making them more efficient compared to the average robot vacuums that clean using a random pattern.
But the models using LIDAR are very intelligent. They create high-precision maps of your house, and the higher-end models have extras, which we’ll be discussing in the next section.
Roborocks, just like Roombas, can scan your entire home and store the map for future reference. In the works is a feature which we understand will enable the robot to store several maps, making it best for households with more than one level.
5. Smart Connectivity
None of the Roborock and Xiaowa vacuums in this review come with a remote control. But that doesn’t mean that the operation means are limited.
Voice Prompts and Assistant
First, Roborock and Xiaowa vacuums have voice prompts, which are far much better than the beeps other robot vacuums have.
Furthermore, the pronunciation is on point, so at no time will troubleshooting your Roborock be a problem.
In addition to the inbuilt voice function, you can operate these vacuums using any of the smart speakers. It tags along with Alexa, and Google Assistant compatibility so you can clean the house by just instructing your Roborock, via Alexa.
Mobile App & Features
While all the Roborock and Xiaowa vacuums have voice prompts and support voice assistants, there is a difference when it comes to the app features. The low-end models have fewer features, while the high-end models have more features. This is despite both models having support for both the iOS and Android mobile apps, as well as the Real-Time Robot Location function.
One of the most coveted features is No Go Lines, and here, only the Roborocks have been designed with this technology. If you have areas where you don’t want the robot to reach, don’t buy Xiaowa as they lack the No Go Zones boundary marking technology. And it’s very simple to use, just mark the areas on the floor planner where you don’t want the robot to reach, and it’s so accurate.
Another superb mobile app feature is the Room Select function, a reserve for the new generation models only (Xiaowa E35, Roborock S4, S5 Max, S6, and S6 Pure). For starters, the Roborock Room Select function allows homeowners to name the individual rooms and thus offering flexibility as far as scheduling is concerned. You can tell the robot when to clean, which rooms, which days, and at what times. And it’s not just the schedule, you can tell it to clean rooms when there are lots of messes, at higher power levels, and others, at low power level.
Zone Cleaning is another great feature worth mentioning, and as the name suggests, it comes in handy when there are specific spots to be cleaned, instead of the entire room, or house. Just tap on the area from the app, and the robot will zero in on that spot. This feature is available in Roborock vacuums only, Xiaowa lacks Zone Cleaning.
Which is the best Roborock vacuum?
Now, we have come to the end of this Xiaowa E25 vs. E35 vs. Roborock S4 vs. S5 vs. S5 Max vs. S6 vs. S6 Pure comparison review. Now, which is the best choice? Here are our top three picks, and the reason why we find it a worthy Roborock vacuum to feature on your wishlist.
If you are on a budget, the Xiaowa vacuums will be the best choice.
The battle was definitely between Xiaowa E25 vs. E35, and definitely, the E35 takes the crown. This is because the E3 has 2000pa suction power, and a larger 5200mAh battery. This is compared to the E25 that has a 2600mAh battery.
Otherwise, all other features are standard. For homeowners with a small apartment, without carpets, the E25 is still a great purchase, but to be on the safe side, go for the E35.
But what if you want the premium features – talk of Zone Cleaning, Map Saving, LDS Laser Navigation, Adaptive Route Algorithm, and Top-Up Charging. Here, you will have to sacrifice the mopping function and get the Roborock S4.
This vacuum boasts all the smart features a standard Roborock vacuum has and costs much cheaper. With a few discounts here and there, this might end up as a race between Roborock S4 vs. S5 now that there is the S5 Max, an upgraded model of the original Roborock.
Now, what if you want the best Roborock to buy, the battle is between Roborock S5 Max vs. S6. These two are the best Roborock vacuums so far, but one of them has the edge.
If you are looking for the best all-round Roborock, the S5 Max is the best choice as it offers solutions to some of the flaws of the S5 and the S6.
This is especially when it comes to mopping function. The S5 Max is more intelligent, and does a better job on both bare floors and carpets, compared to the S6. That makes it our best choice in this comparison review.
How to create No Go Zone on Roborock S5
Open the Home app and tap on the device you have, that is the S5, and then tap the right corner and go to Vacuum Settings, and turn on map saving, if it is off. Now, go back to the floor screen and tap the Edit Map option, and go to “No Go Zone.” Add a new zone, and draw the limits, and save. The system allows for up to 10 No Go Zones.
How to turn on mapping on Roborock S6
There’s no difference here; it’s the same as the S5. Choose the device, tap the right corner and navigate to Vacuum Settings, and turn on the map saving function. The S6 can save up to 3 maps – the current map, barrier, and No-Go Zone, and the last is the cleaning log of the previous session. The Roborock S6 doesn’t save each floor plan’s map permanently and instead refreshes the map each time. But the barrier and No-Go Zone settings can be saved after that.
How to change Roborock filters
All these vacuums require maintenance, and here there is the daily maintenance and long term maintenance. To change the filters of the S5, S6, S5 Max or the S4, open the top panel of the unit, and press the release button to eject the bin. Open the lid and remove the filter from the bin. Wash it and install it back. You will need a replacement in 3 to 4 months but keep checking for any signs of wear.
