Practical Kyvol Cybovac E31 robot vacuum cleaner: Excellent cleaning, poor mapping of the application
There is a lot to love with the Kyvol Cybovac E31 robot vacuum. It is a sweeping and cleaning robot combined with a simple app and Alexa integration.
The E31 has a lower profile than other robots I’ve tried. At 2.85 inches, it can fit under furniture that overturns other robots with top-mounted LIDAR protrusions. It’s a sleek, one-button robot that combines power and home switches.
In use, its 2200Pa motor is quiet and efficient, and its cleaning is good. The E31 connected to its app faster than any other robot I’ve tried. It was a pleasure to connect. The application is ultra-simple.
You can set the controls to follow an automated schedule for sweeping or cleaning, set the amount of water, and specify how much suction power you want when sweeping. You can also manually control the robot when it is in use, or set the controls for edge or spot mode.
The app also creates a map of the area, although this map bears no relation to maps generated by other robot vacuums that I have used. The map generated by the Cybovac E31 did not look like space at all. There is also no option to update or delete the map.
Although simple to connect, I found that the app lacked many features common to other vacuum cleaners. Unlike vacuum cleaners like the Roborock S6 MaxV, Deebot OZMO T8, or the Neabot, you cannot define no-go zones that the robot will not enter.
The E31 has bounding strips which are physical magnetic tapes that the robot will not cross.
The robot will clean for more than two hours before returning to its dock to recharge. The cleaning and sweeping function is really useful, although cleaning should be considered as daily cleaning. It won’t remove heavy dirt, but it is useful for light soiling.
Its 600ml dust bin means the bin only needs to be emptied weekly, if used on hard floors, or once every three days if used on carpeted floors.
One problem I had was that the Cybovac had difficulty returning to its original base if the base was in a different room. I think this is due to the incomplete mapping of the area by the robot.
However, the robot got lost about four times during its entire service life.
Every time I looked at the app the map for the same area looked different. Perhaps this caused the problem, as there were no other mitigating factors such as partially open doors or a new environment to contend with.
However, this question was not an obstacle for me. Many other robots get lost in space. Some beeps, some emit voice alerts. The E31 wandered around at random until it finally discovered its base station.
Overall, this is a nice, low profile, two-in-one sweeping and mopping robot with an easy-to-connect app. If you need simplicity in a robot vacuum cleaner and an app, then the Kyvol Cybovac E31 is the robot for you. Just make sure it doesn’t get lost too often.
