  • Patent number: 11844475
    Abstract: A robot cleaner of the present disclosure includes: a main body forming an outer shape; a pair of rotary mops configured to rotate in contact with a floor to move the main body; a drive motor configured to rotate the pair of rotary mops; a mop sensing unit comprising at least one micro switch provided on a surface of the rotating plate configured to output a sensing signal when the mop cloth is attached; and a controller configured to determine attachment state of the mop cloth based on the sensing signal and control the driving of the rotary mop. Accordingly, the robot cleaner may detect whether the mop cloth is attached to the rotating mop, and alert the user, thereby protecting the floor by preventing wet cleaning without the mop.
    Type: Grant

  • Patent number: 11786098
    Abstract: A robot cleaner of the present disclosure includes: a robot cleaner including: a main body forming an outer shape; a water tank configured to contain water; a pair of rotary mops configured to rotate in contact with a floor to move the main body; a drive motor configured to rotate the pair of rotary mops; a pump connected to the water tank for injecting the water to the rotary mop; and a controller configured to determine whether the water in the water tank is insufficient based on an output current of the drive motor indicating a water content of the rotary mops. Accordingly, the robot cleaner may be effective in terms of cost and space utilization because it does not have a separate water quantity sensor and can measure the water quantity of the rotary mop of the robot cleaner.
