Roborock S6 vs. Roomba i7+: The Differences Explained

By Natalie Red·Updated: Aug 29, 2019· 8 min read

Both of these robots are great. The Roborock S6 and Roomba i7+ are flagship models. They both remember your floor layout, navigate in straight lines, do not leave any area untouched. Both are able to identify carpet flooring and boost suction once the robot steps on one. 

The Roomba i7+ brings to the table a new feature — self-emptying charging base. The Roborock S6 does mopping, not only sweeping. Do you want the robot to clean a kitchen directly? Both models support selected room cleaning.

Roomba i7+

The Roomba i7+ is the first iRobot that has a self-emptying charging base. It is equipped with two brushless rollers that are tangle free and perfect for pet hair. One side sweeper catch debris along the walls sending them to the suction path. The robot vacuum is equipped with a bunch of sensors that help it to navigate around including a camera sensor. The camera scans a cleaning area creating a map of the interior. The charging base is taller (19 in) than most of the docks we've seen. 

When the Roomba docks itself back at the charging base, a suction force pulls the debris out of the dustbin on the i7 vacuum and into the bagged container enclosed within the charging base. The bagged system can store up to 30 loads of debris from the i7 cleaning cycles.

In the box, one virtual wall supposed to help with navigating tricky spaces or to block off a sensitive area. 

Inside the dustbin, a small HEPA filter that makes the Roomba safe for people with allergy or asthma.

How does the self-emptying base work?

When the dustbin inside the Roomba gets full, the robot vacuum returns to the charging dock, the base sucks up the debris from the container. When the Roomba is done emptying, it returns to continue cleaning. The base holds up to 30 robot's bins, so you don't have to empty it for about a month. 

When the Roomba finishes cleaning, you can see the results in the cleaning history. The Roomba i7+ cannot be tracked in real-time, you can't see its location when the robot is vacuuming. 

Thanks to mapping, the robot knows where to clean and does not miss any spot. After the cleaning is finished, you can divide the map into separate zones and name each. With this feature, you can schedule the Roomba i7+ to work directly in the kitchen, bedroom, living room, etc. Also, if you own an Alexa-enabled device or Google Home, you can say things like: "Alexa, clean the kitchen" and the Roomba will do the rest. 

The Roomba i7+ has dirt detect, it recognizes high-traffic areas providing deeper cleaning on those spots

The Roomba i7+ is the first model in the family that supports saving up to 10 floor plans. If you live in a house with more than one level, the Roomba i7+ would be perfect for you. If you take the Roomba to a different level, it will retain the mapping information.

Tangle-free rollers are ideal for pet hair

The Roomba robots have a tendency to fling the debris around, and the i7+ is no exception. With big messes on bare floor, the i7+ tends to scatter particles, however, on carpet, it works fine. 

Roborock S6 

The Roborock S6 has a rubber side brush and a cleaning brush that has detachable parts. The brush is a mix of rubber and stiff bristles. The Roborock S6 is claimed to be tangle-free. Since it is not brushless as the one inside the Roomba, it is still one of the best roller suitable for pet hair. 

The Roborock is equipped with 14 sensors to navigate around including an LDS laser to create a map of the cleaning area. The LIDAR mapping technology allows the robot to clean in the dark. 

Under the lid, a 500 ml container with a HEPA filter that can be washed, making the robot vacuum safe for allergy and asthma sufferers.  


Three processors located inside the Roborock S6 allow tracking the robot in real-time which you can see in the Mi Home app. When the robot vacuum is working, you can check its location using the app. 

The S6 supports restricted areas. There is either can be a barrier tape or a rectangle that creates a blocked zone. This feature is helpful when you don't want the robot to go to some specific areas. 

Zoned cleaning. With this option, you can create a rectangle on the map to make the robot work within the chosen zone. 

Selected room cleaning. When the Roborock S6 finishes cleaning, it creates a map that is divided into separate rooms. You can merge or divide zoned as you want if you don't like the way the Roborock did. 

The Roborock S6 can be scheduled to work within one or a few rooms further. This option is great since sometimes you don't want to clean the whole house, some rooms like a kitchen get dirtier sooner than saying a guessing room. 

Zoned cleaning cannot be scheduled, when the selected room can. 

The Roborock S6 saves up to three different maps

The Roborock S6 comes equipped with a water tank and two types of mopping pads: 10 disposable pads more suitable for everyday cleaning, and two microfiber cloths for mopping one-two times a week. The tank has a switch that controls the level of water dripping depending on the amount of water you need. 

The Roborock S6 does sweeping and mopping at the same time

We got to test the Roborock S6, it did not seem to have any issues with cleaning. The pickup ability is pretty good, the robot does not struggle with bigger particles neither does with ultra-fine debris on bare flooring, thin and medium-pile carpets.
