Today’s debate pits two popular robot vacuums: Roomba Combo i5 vs. i7. What is the difference between the Roomba Combo i5 and the Roomba i7? What about the similarities? Which is the best model? If you are in this dilemma, we have the answers.

Roomba Combo i5 and i7 are two of the robot vacuums in the Roomba I Series. The two share quite a lot. They are both hard floor cleaners and can handle carpets and pet hair as well. They share several other features. However, there are profound differences that should inform your choice.

Important

The main difference between the Roomba Combo i5 and i7 is the cleaning orientation. The Roomba Combo i5 is a new 2-in-1 cleaner that vacuums and mops simultaneously. On the other hand, the Roomba i7 has been designed to vacuum only. Of course, there are some other nitty-gritty differences that we will talk about in detail.

Keep it right here for more regarding how the Roomba Combo i5 compares to the Roomba i7.

Roomba i5 vs. i7 Comparison Review: Similarities and Differences Explained

Now, onto the main section of this Roomba comparison review: how does the Roomba Combo i5 compare to the Roomba i7? To ensure you make the right decision, the comparison will be based on essential factors considered when buying robot vacuums. Just to mention, there are several variants of the Roomba i5 and i7. For this review, we have focused on the respective base models: Roomba Combo i5 and Roomba i7. Without further ado, let's get started.
1. Design Dimensions and Aesthetics
round-shaped

Nothing has changed in the Roomba Combo i5 as far as design is concerned. It is also a round-shaped robot vacuum with a low-profile design.

It can pass between tight spaces and go under furniture without being restricted or getting stuck. The diameter is 13.4 inches, while the height is 3.6 inches. As for the weight, the i5 Combo averages 7 lbs.

Regarding build quality, we like the sturdy design courtesy of high-grade materials guaranteeing durability.
The Roomba i5 Combo has been finished in black and woven textured grey.

round-shaped

Roomba i7 is also a round-shaped robot vacuum like most other Roombas and maintains a compact and low-profile design.

It can pass between tight spaces and go under low-profile furniture without getting stuck. The dimensions are 13.4 inches in diameter and 3.63 inches high, while the weight is 7.44 lbs.

The Roomba i7 also boasts a premium build quality that can withstand accidental falls and pet scratches. The robot is black.

There is no winner in this first round, as both models are round-shaped and have compact, low-profile designs. The craftsmanship is also excellent.

2. Cleaning Orientation
vacuum and mop

Roomba i5 is such a versatile robot cleaner. It offers 2-in-1 cleaning in that it vacuums and mops simultaneously. You can rely on it if you have hard floors such as tile, marble, hardwood, linoleum, vinyl, etc.

The Roomba i5 can also handle carpets, but remember to swap the Roomba Combo Bin as it tends to wet carpets. For homes with pet hair and other pet messes, the Roomba i5 also suffices.

vacuum only

One of the differences between Roomba Combo i5 and i7 is the cleaning orientation. While the Combo i5 has been designed to vacuum and mop, the i7 is designed to vacuum only. There is no mopping function.

As for specialization, the i7 is also a good robot vacuum for hard floors, including tile, hardwood, marble, laminate, vinyl, you name it. You can also use it on carpets, but the suction is average, so you are not guaranteed thorough vacuuming on thick carpets. Last, the Roomba i7 is a reliable robot vacuum for pet hair and related messes.

Both Roomba i5 Combo and i7 are ideal for cleaning hard floors, carpets and pet hair. But ultimately, the Roomba i5 wins the round as it is a 2-n-1 cleaner that vacuums and mops. You don't need a separate robot mop.

3. Vacuuming Performance
850 - 900 Pa

Roombas work by sucking up debris, from fine debris to large debris. An inbuilt motor generates the suction. The Roomba i5 has a 2nd Gen motor that delivers 10x the power-lifting suction of old series models such as the Roomba 675 and the rest.

This is a single-speed motor, so don’t expect suction adjustment features such as carpet boost. The average yield of the Roomba i5 is 850 – 900 Pa, while operation noise is around 65 dB.

850 - 900 Pa
roomba i7 Cleaning Performance

Roomba i7 is not different regarding vacuuming performance as it is equipped with the same Roomba Gen 2 motor. It also delivers 10x the power-lifting suction of the Roomba 600 series models, producing a suction of 850-900 Pa.

Like the Roomba i5, the i7 doesn’t have adjustable suction levels or any feature similar to carpet boost. The operation noise averages 65 dB.

This round has no winner as both models are equipped with the same 2nd Gen motor and deliver 850-900Pa. The operation noise is also the same. Below are the cleaning test results.

4. Mopping Performance
Yes

Roomba i5 Combo can vacuum and mop. The mopping mechanism is quite basic. To mop, you need to change to the Interchangeable Roomba Combo™ Bin and fill water and cleaning solution, preferably Bona Hard-Surface Floor Cleaner.

The Interchangeable Roomba Combo™ Bin holds the mopping pad, which is effective in scrubbing and eliminating tough stains and grime. Unfortunately, the Roomba i5 doesn’t detect carpets, so it might wet them.

Your only option to prevent the robot from wetting carpets is swapping the Interchangeable Roomba Combo™ Bin for the standard bin.

No

Roomba i7 is not a 2-in-1 cleaner like the Roomba Combo i5. There is no mopping function.

Instead, it features Imprint Link Technology that allows you to sync the robot vacuum with the Braava M6 robot mop.

Here, it is obvious that the Roomba i5 is the best choice. It comes with vacuum and mop functions, meaning you don't have to spend more on a separate robot mop.

5. Navigation System
iAdapt 1.0

Roomba Combo i5 may be among the latest Roombas, but it still relies on an old-generation navigation system. This is iAdapt 1.0 SLAM navigation. For obstacle detection and preventing the robot from falling off the stairs, the i5 uses obstacle and anticliff sensors.

There is no real-time camera. The robot also lacks any form of advanced obstacle-detection technology. We tried it in a high-traffic room, and it performed well despite hitting some obstacles.

iAdapt 3.0

One of the differences between the Roomba Combo i5 and the Roomba i7 is the navigation system. The Roomba i7 uses the latest iRobot navigation system, iAdapt 3.0 VSLAM Navigation. There are sensors for obstacle and cliff detection alongside a real-time camera.

With the real-time camera, the robot can avoid obstacles with better precision. We tried it in a high-traffic room, and it managed to avoid most obstacles better than the Roomba i5.

In this round, the Roomba i7 is the best choice as it has a much-advanced navigation system that combines sensors and a real-time camera for better navigation and obstacle avoidance.

6. Mapping System
Imprint Smart

Roomba i5 has an outdated navigation system, but we are glad it is a smart mapping robot vacuum. It relies on Imprint Smart Mapping technology to learn, map, and adapt to the floor plan of your home. It knows where the living room and kitchen are, so you can customize cleaning by room.

Unfortunately, there is no Keep Out Zones or No Mop Zones.

But we have iRobot OS cleaning extras, including Clean While I’m Away, Cleaning Time Estimates, Smart Map Coaching and Room Name Suggestions, and Quiet Drive.

Imprint Smart

Roomba i7 is also a smart robot vacuum that uses Imprint Smart Mapping. Like the i5 Combo, the i7 can also learn, map, and adapt to the layout of your home.

It can also identify the different rooms so you can choose to clean the kitchen only and skip other rooms that don’t necessarily require cleaning. Clean by zone features such as spot cleaning and boundary marking (Keep Out Zones) are also available, and so are the iRobot OS features.

These are Clean While I’m Away, Cleaning Time Estimates, Smart Map Coaching and Room Name Suggestions, and Quiet Drive.

This round has no winner as both robot vacuums use Imprint Smart Mapping and are powered by iRobot OS.

7. Filtration System
AeroForce

Roomba i5 doesn’t just vacuum and mop. It can also keep your ambiance fresh. The robot has a filtration system that consists of an AeroForce high-efficiency filter.

The filter is 99% efficient and captures all kinds of allergens, pollen, dust mites, and other elements that can bring discomfort.

AeroForce
Roomba i7+ Filtr

There is nothing different in the i7. This robot can also help eliminate allergens and other elements that cause bad odor.

It is equipped with an AeroForce high-efficiency filter that captures 99% of allergens and other elements from the atmosphere. Whether it’s allergens or dust, the Roomba i7 has got you covered.

This round ends in a draw as both robot vacuums have the same filtration system consisting of an AeroForce high-efficiency filter.

8. Brush System
Dual Multisurface Brushroll

For sweeping and agitation, Roomba i5 comes with an elaborate brush system consisting of a main brush and a secondary brush. The main brush is a Dual Multisurface Brushroll with Tangle-Free Technology.

It consists of two rubber brushes, one for agitating dirt and the other for dirt lift-up. We also like that it has been redesigned to prevent tangling, so you won’t have trouble with a jammed brush.

The main brush is complemented by a spinning side brush that sweeps the deep corners and wall edges.

Dual Multisurface Brushroll
Roomba i7+ Brush system

Roomba i7 is the same as the i5. It also comes with a Dual Multisurface Brushroll with Tangle-Free Technology.

The main brush consists of two brushes, one for agitating and loosening dirt and the other for lifting dirt from the floor or carpet, ready for suctioning.

This, too, is an anti-tangle brush, so the brushroll won’t get jammed easily like in typical robot vacuums. The Roomba i7 also has a spinning side brush for the wall edges and corners.

This round has no winner, as the Roomba Combo i5 and i7 have the same brush system, a Dual Multisurface Brushroll with Tangle-Free Technology, and a spinning side brush. Their performance is at par.

9. Bin System
Onboard

The Roomba i5 has a large onboard bin. There is a full bin indicator to alert you when it is time to empty the bin. For the record, the Roomba i5 is a self-emptying robot vacuum, But the model in this review, the Combo i5, doesn’t come with the Automatic Clean Base Unit.

If you want a package with this unit, get the Roomba Combo i5+. With the Clean Base unit, you can forget about manual bin emptying for up to 60 days.

Onboard

The Roomba i7 is similar to the i5 here. It also has a large onboard bin that can hold dirt for a few days and a full bin indicator so you won’t miss an emptying session. Roomba i7 is also a self-emptying robot vacuum, but the model in this review, the Roomba i7 (7150), doesn’t include the Automatic Clean Base unit.

If you want a model with an auto-empty unit, go for the Roomba i7+ (7550). With the Clean Base unit, you can enjoy the convenience of hands-free cleaning for 60 days.

There is no winner here. The Roomba i5 and i7 have onboard bins with the same capacity and work with the iRobot self-emptying technology.

10. Battery and Runtime
1,800mAh/75 minutes

Roomba i5 comes with a lithium-ion battery whose 1,800mAh capacity can power the robot for a cool 75 minutes. We like the fact that this is an intelligent robot vacuum with Auto-Recharge+Resume capabilities.

When the battery level goes down, the robot docks, recharges and returns to finish the job from where it left off. The recharge time is 2-3 hours.

1,800mAh/75 minutes

Nothing is different with the Roomba i7, as it also has a 1,800mAh lithium-ion battery. This battery can last the robot for a cool 75 minutes.

The Roomba i7 maintains the Auto-Recharge+ Resume function. It will dock and recharge automatically and resume cleaning after that to complete the task at hand. Recharge time is also 2-3 hours.

Here, it is hard to call a winner as both models have the same 1,800mAh lithium-ion battery that offers 75 minutes of runtime on average. The Auto-Recharge+Resume function is available for both models.

11. Automation and Smart Features
WiFi, App, Alexa

Roomba Combo i5 is well-endowed in terms of smart features and convenience. The robot has a schedule function that allows you to set preferred cleaning times throughout the week. We also like the fact that it is compatible with 2.4GHz WiFi for remote operation.

You can use the iRobot Home App or voice assistants, including Alexa and Google Assistant. One feature we like is iRobot OS, which offers personalized cleaning suggestions and tags along with several other features, including Clean While I’m Away and Quiet Drive.

WiFi, App, Alexa

Roomba i7 is similar here as it also has a schedule function so you can program the robot to clean at specific times throughout the week. The i7 is also a smart robot vacuum courtesy of 2.4GHz WiFi compatibility.

You can operate the robot via the iRobot Home App or even sync it with voice assistants such as Alexa and Google Assistant. Like the i5, the i7 also comes with iRobot OS, which offers personalized cleaning suggestions, among other peaks.

There is no winner in this round, as both Roombas can be programmed. They also support mobile apps and voice assistant operation and are powered by iRobot OS.

12. Warranty & Aftersales
1-year

Despite being a robust robot vacuum, the robot further reassures customers of the quality of its products by accompanying the Roomba i5 with a standard Roomba 1-year warranty.

Regarding support, iRobot is easily accessible via the live chat available on the company website. You can also use other resources, including troubleshooting guides and manuals. As for Roomba i5 replacement parts and supplies, you can find them in plenty on Amazon.

1-year

Roomba i7 also tags along with a standard Roomba 1-year warranty. In case the robot develops a problem within the first year, you can get a repair or a replacement.

Support is also available via the iRobot live chat feature and other resources, including Roomba troubleshooting guides and user manuals. Replacement parts and supplies can also be purchased on Amazon.

There is no winner in this round. The two robot vacuums are from the same brand, so the warranty and aftersales are the same.

  • Home Base Charging Station
