Abstract: A robot cleaner includes a main body forming an exterior and having a water tank housing formed at a rear side thereof. The water tank housing may form a space in which a water tank is mounted. At least one spin mop is rotatably provided at a lower side of the main body, moving the main body by rotating, and configured to clean a floor using water in the water tank. A supply nozzle is provided at one side of the water tank housing, and when connected to a discharge nozzle of the water tank, communicates with the discharge nozzle to supply water stored in the water tank to each of the spin mops. The robot cleaner further includes a locking device rotatably provided at a position spaced apart from a circumferential surface of the water tank housing, and configured to secure the water tank in the water tank housing when mounted or to release the water tank by pushing backward on the water tank.

Abstract: A robot vacuum cleaner includes a main body that moves along a surface, draws in dust from the surface, filters the dust, and discharges air. A water tank is detachably mounted on a lower surface of the main body, and a damp cloth is mounted to the water tank. The water tank stores water in a filling space and supplies water from the filling space through a water supply unit mounted on a lower surface of the water tank to the damp cloth. An air inlet is formed on an upper surface of the water tank. An air inflow member selectively opens the air inlet to allow outside air to flow into the filling space when the main body moves, and closes the air hole when the main body stops moving.
