Both the Roborock S6 MaxV and the Roomba i7 sport a slim, round profile and their sensors are mounted at the top of their faceplates.

While they look similar at a glance, taking a closer look at the Roborock S6 MaxV and the Roomba i7 will show noticeable differences in design. The Roborock S6 MaxV (left) is equipped with laser sensors at the top of its faceplate and its front houses dual cameras for better depth perception. Because of this, the Roborock S6 MaxV‘s height is taller than the Romba i7 that has a flat faceplate. Similarly, the Roomba i7 (right) camera-based sensor is mounted at the top, but it is not protruding which is the case for most robot vacuums with LiDAR sensors.

Another difference between the Roborock S6 MaxV and the Roomba i7 is their dustbin capacity. The Roomba i7 has a larger 700mL dustbin whereas the Roborock S6 MaxV‘s is 480mL. While not as large as the Roomba i7‘s, the Roborock’s dustbin size is still bigger than many robot vacuum’s. This is because the S6 MaxV has an electronic water tank for mopping.

Both their brushes are located at the middle of these robot vacuums and are almost the same size. However, the Roomba i7 is equipped with iRobot’s patent dual rubber brushes that don’t have bristles. The Roborock S6 MaxV still has bristles, but both robot vacuums can resist hair tangles well. Another difference is the Roborock S6 MaxV can be attached with a mop for a more thorough clean.

Cleaning Performance & Mopping

The Roborock S6 MaxV has significantly stronger suction power and can pull in finer particles better

Robot vacuums by Roborock have continued to impress with their cleaning performance. With 2,500Pa of suction power, the flagship Roborock S6 MaxV packs powerful suction and can pull in finer dust even from crevices and carpets. The Roomba i7, with a motor suction of up to 1,700Pa, also delivers excellent cleaning and can pull in debris without issues. However, it doesn’t do as great of a job when it comes to sucking finer particles.

Another difference between the Roborock S6 MaxV and the Roomba i7 is their mopping capabilities. The Roborock S6 MaxV doubles as a mop. It comes with a mopping attachment and an electronic water tank that lets you customize the water settings. While theS6 MaxV’s mop is not for heavy-duty cleaning, it does a good job of mopping light floor stains. As for the Roomba i7, you can link the iRobot Braava jet (sold separately) to the Roomba i7. The Braava jet will mop right after the i7 finishes vacuuming.

Mapping & Navigation

The Roborock S6 MaxV‘s laser sensors and camera make its mapping and navigation more accurate than the camera-based Roomba i7

These robot vacuums clean in straight paths and can remember different rooms and floor levels

The Roborock S6 MaxV employs LiDAR (Light Detection and Ranging) technology for its navigation system. Apart from its laser sensors, it also has stereoscopic vision cameras at the front for better object identification. Because of its laser sensors, the Roborock S6 MaxV can path more efficiently and accurately than the camera-based (vSLAM) Roomba i7. With that said, the Roomba i7 can still map your home and avoid obstacles well.

If there are certain areas or rooms you want your robot vacuum to keep out of, both the Roborock S6 MaxV and the Roomba i7 let you set-up virtual wall barriers and keep out zones. Again, the S6 MaxV outperforms the Roomba i7 in this department because of its laser sensors. Both robot vacuums are great for large homes as they can map and remember different floor plans in your home. When it comes to their apps, however, the Roomba’s is more reliable.

Battery and Additional Features

The Roborock S6 MaxV has a longer runtime while the Roomba i7 can be upgraded with a Clean Base for automatic dirt disposal.

Another feature that makes the Roborock S6 MaxV a perfect cleaning companion for larger homes os its long battery life. It boasts a runtime of up to 180 minutes, an hour more than the 120-minute runtime of the Roomba i7. They can both trek back to their charging base as needed and resume cleaning automatically. You can further use either robot vacuums with Amazon Alexa or Google Assistant.

Perhaps another factor you may want to consider when deciding on your premium robot vacuum is the ability to upgrade with a Clean Base Automatic Dirt Disposal Technology. Most robot vacuums today, no matter how smart, still requires regular dustbin emptying. iRobot tries to solve this through its Clean Base that automatically empties the Roomba’s dustbin. With this, you can forget emptying the dustbin for weeks, if not months. The Roomba i7 can be upgraded with the Clean Base while the Roomba i7+ automatically comes with one.


If you can catch the Roomba i7 while it’s on sale, it offers better value for your money as it can be upgraded with a Clean Base. If not, get the Roborock S6 MaxV.

With their regular price, the Roborock S6 MaxV offers better bang for your buck as it retails for 749USD while the Roomba i7 costs 699USD. However, this is a tough call as at the time of writing, the iRobot Roomba i7 is on sale and only costs 499USD, giving you around 200USD in savings.

While not as powerful as the Roborock S6 MaxV, the Roomba i7 is still an excellent option, especially if you see yourself upgrading with a Clean Base in the future. However, if you missed the sale, the Roborock S6 MaxV is the more worthwhile purchase between the two.
