摘要

A robot cleaner (100) and a control method thereof may judge whether or not water is received in the robot cleaner (100) performing wet cleaning. The robot cleaner (100) includes a main body (110), moving units (150), a cleaning unit (160) mounted on the main body (110) and contacting a floor surface to perform cleaning, a water supply unit (170) supplying water to the cleaning unit (160), and a sensing unit (180) provided on at least a portion of the water supply unit (170) to sense whether or not there is water within the water supply unit (170). The sensing unit (180) includes a housing (182), a transmission part (187) radiating electromagnetic waves, a reception part (188) receiving the electromagnetic waves radiated by the transmission part (187), and a stepped part provided on at least a portion of the housing (182) along a moving path of the electromagnetic waves radiated by the transmission part (187) and received by the reception part (188).
