The Mint 4200 Robotic Hard Floor Cleaner does not have suction or a motorized brush. It relies on a damp or dry microfiber towel to pick up dirt, pet hair and dust. Since this doesn’t have any suction, you can’t use this on carpet. It’s purely a hard floor surfaces only like tile or linoleum.

Since it doesn’t have a vacuum motor, the run time will be impressive at around 3 hours. Run time is long enough to clean a 800 square foot home in dry mode and 250 square foot in wet mop mode.

For navigation, it uses the so-called “NorthStar Navigation System” that works like an indoor GPS to navigate the robot.
