The new age of the robot vacuum allows not to think about maintenance as much and let the robot do the job on its own. Some most-featured robots clean themself and by that I mean it doesn't only self-empties the dustbin but also wash the mopping pads. Back in the day, the robots either did one thing or another but not both at the same time. In 2022 we can see some models having all the features we wished for back then.
Today we are talking about 4 of them, the Xiaomi All-in-One, Roidmi Eva, Roborock S7 MaxV, and Deebot X1 OMNI PLUS. They all look kinda similar but the Roidmi is much cheaper and let's see what is the reason for that.
All of these models have a self-cleaning base, Lidar to map the cleaning area, three of them additionally have a built-in camera to recognize small objects, and all of them have a mopping feature. All of them have the restricted area feature, zoned cleaning, room cleaning and other features available in most robots these days.
Let's talk about each.

Object recognition
Object recognition is a function that was only available in premium robots back then but not anymore. Even the medium-priced robots might have it so it's not that rare anymore. Most premium robots navigate by using Lidar which scans the surroundings to create an accurate map that is being followed further on. Object recognition allows a robot to see small objects Lidar can not identify. Object recognition technology is normally a camera or 3D sensor located on a bumper that tracks some small things, calculates the distance for it, and possible ways to avoid a certain object. The 3D sensor is a cheaper technology, it lacks some features the camera has. The three of the robots on this list are being navigated via a built-in camera. A camera is more precise and is able to take pictures of an object as well as leave a mark on the map where the object is located.
One of the reasons the Roidmi is much cheaper is a lack of object recognition. It only relies on Lidar and as a result, its navigation is not as accurate.
- The Xiaomi, DEEBOT, and Roborock have a built-in camera to recognize small objects
- The Roidmi Eva does only uses Lidar to navigate
Cleaning brushroll
A cleaning brushroll takes a big part of a cleaning mechanic starting with performing on carpet and ending up with ease of maintenance.
- The Xiaomi, Roidmi, and DEEBOT use a standard brushroll with rubber and bristles. They are a bit harder to maintain compared to the rubber one.
- The Roborock has a fully rubber roller that is very easy to maintain but has its issues with picking up pet hair on carpet.
A fully-rubber brushroll the Roborock does a great job on carpets but kinda struggles with picking up pet hair on it. It deals with pet hair on hard floor, but not really doing the thing on carpet. Has no issues with other types of debris, just my personal experience with the Roborock S7 I have tested. I do believe the S7 MaxV does it much better as it is more powerful. Another pro of a bristles brushroll is how easy it is to maintain. It resists hair tangles and even if it does get some hair around the roller after cleaning, removing it takes a few seconds.
The standard brush is kind of a mutual as it does the job on carpet as well as picks up pet hair on it and probably is better the last thing because of bristles that agitate hair. However, a standard brush is not as good at performing a deep clean as a fully-rubber one. So there is a balance between a good cleaning and collecting pet hair on carpet.
The other three have a standard brushroll that is a mix of rubber and bristles.
The self-cleaning base that does it all for you
The self-cleaning base is the main reason why these robots are so expensive. Each base contains two large water tanks, one for clean and one for wasted water, and additionally a disposable bag. The base has the following functions:
- Auto-refill water tank (except for the Roidmi Eva)
- Self-wash (all of them)
- Self-emptying (all of them)
- Drying the pad (all of them)
- Self-clean (only the Roborock)
The water tanks wash a mopping pad and also fill a water tank inside the robot. When the robot returns to the base, the clean water container supplies water to wash the pads and circles to the wasted water container so the pads are always clean and ready to be used the next time. After washing, the base dries out the pads with hot air preventing humidity and bad smell.
Another option is self-emptying the dustbin which is not new, many robots already have it. A disposable bag located inside the dustbin collects debris for up to 2 months so you neither have to empty the dustbin manually nor replace the bag for at least a month depending on usage.
The Roidmi Eva does not have a small water tank inside the robot so its base does not refill it, only has washing and drying functions. That is another reason for the robot being cheaper.
However, its self-emptying base has some features other models don't, the display. It shows when the waster water container is full, the base cleaning status, when the dust bag gets full, when the clean water container has to be refilled, battery level, and mop drying indicator. I think this is a very useful feature and have no idea why other manufacturers don't implement it to the self-cleaning base.
The Roborock S7 MaxV Ultra, additionally to all these features also has a self-clean option that washes the base so it stays clean after washing the mopping pad.
Mopping system what is the difference
One of the differences between the models is the mopping system. Firstly, it's the mopping pad type each uses. The Roidmi, Deebot, and Xiaomi have two rotating pads while the Roborock has a single mopping pad that vibrates. All 4 models support restricted areas if needed.
The Xiaomi and Roborock lift up the mopping attachment when the robot steps up on carpet making cleaning more convenient as the user doesn't have to vacuum carpets on the second go. The DEEBOT, on the other hand, avoids carpets automatically with mopping attachments on. For the Roidmi, you have to set no-go zones so it doesn't cross a carpeted area.
All of them return to the base to wash the pads after mopping and each system has a drying feature.
So in short:
- The Xiaomi All-In-One has two rotating pads and lifts the pads on carpet.
- The DEEBOT X1 OMNI has two rotating pads and avoids carpets in mopping mode.
- The Roidmi Eva has two rotating pads and does not avoid carpets on its own, you have to set restricted areas. It also does not have a water tank inside.
- The Roborock S7 MaxV Ultra has a single mopping pad that vibrates creating more pressure on the floor.
Roidmi Eva
The cheapest robot vacuum that washes the mopping pads and empties the dustbin. Additionally, the only one with a display on a self-cleaning base although lacks object recognition, and a small water tank so might not be as good at mopping as the others.

Rises the pads on carpet
More affordable compared to the DEEBOT and additionally has a lifting feature. Not widely available yet tho.
ECOVACS DEEBOT X1 OMNI
ECOVACS DEEBOT X1 OMNI
Avoids carpets automatically in mopping mode
Automatically avoids carpets with the mopping attachments on, no need to set restricted areas on carpet. Better to use in homes with mostly carpets or hard floors as the user would have to run the robot twice, firstly to vacuum and mop avoiding all carpets, and the second time to vacuum the carpets.
Roborock S7 MaxV Ultra
Roborock S7 MaxV Ultra
Vibrates and lifts up the pad on carpet
One of the best in the industry. Lifts the mopping pad on carpet and doesn't use the rotating pads but a solid one that additionally vibrates creating more pressure on the floor. Unlike the other three, it also cleans the base after washing the pad which is a nice bonus. Very convenient to use in homes with a mixed surface.
