Robot cleaner and method of controlling robot cleaner

The present invention relates to a method of controlling a robot cleaner, which comprises a pair of rotating plates having mops facing the floor surface coupled to lower sides thereof, and is configured to travel by rotating the pair of rotating plates, the method comprising: a region setting step in which a cleaning region on the floor surface is set; and a travel step in which the robot cleaner travels in the cleaning region, wherein in the region setting step, the cleaning region is set by subdividing same into a plurality of sub-regions. Since the plurality of sub-regions are at least partially overlapped with one another, there is an advantage in that while the entire cleaning region is being cleaned, a certain region may be repeatedly cleaned.
