Abstract: The present disclosure relates to a method of controlling a robot cleaner including a pair of rotary plates having lower sides to which mops facing a floor surface are coupled, the robot cleaner being configured to move by rotating the pair of rotary plates, the method including: a first forward movement step of moving the robot cleaner forward from a starting point toward a predetermined target point; a first rotation step of rotating the robot cleaner; a second forward movement step of moving the robot cleaner forward after the first rotation step; and a second rotation step of rotating the robot cleaner after the second forward movement step, such that the floor surface may be repeatedly cleaned only by the forward movement and the rotation.
