Abstract: A robot cleaner includes a water tank forming a space to store water, a body forming an exterior and having a housing which forms a space in which the water tank is mounted, a pair of spin mops rotatably mounted at a lower side of the body, a first nozzle provided at the housing, a second nozzle provided at the tank and configured to couple to the first nozzle, and a fixing part generating a magnetic force when the tank is mounted in the housing to fix an arrangement of the tank mounted in the housing. The fixing part includes a fixing device (e.g., a magnet or metal) provided around a circumference of the second nozzle and a response fixing device (e.g., a magnet or metal) provided around a circumference of the first nozzle and having a shape corresponding to the fixing device. The first nozzle and the second nozzle are attached to each other by the fixing device and the response fixing device.

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 nozzle for a cleaner has a nozzle main body including an intake channel to suction air. The nozzle includes first and second rotary cleaning units spaced apart from each other in a lateral direction under the nozzle main body. Each of the first and second rotary cleaning units includes a rotary plate coupled to a dust cloth. The nozzle further includes a first driving device to drive the first rotary cleaning unit and a second driving device to drive the second rotary cleaning unit. The nozzle includes a water tank to store water. Further, the nozzle has a water supply channel to supply water in the water tank to the rotary cleaning units. The nozzle has a water pump and a pump motor to drive the water pump to pump the water to the dust cloth.

Abstract: A robot cleaner may have a body, a mop, and a tank to supply water to the mop. The tank may be magnetically coupled to the body via at least one magnet and be physically coupled to the body via a groove and a protrusion The protrusion may be a bent rib extending from the tank to couple to a groove in the body, or the protrusion may be a stopper attached to a spring attached to the body and coupling with a groove in the tank. The at least one magnet may be provided at a first side with respect to a left-right center, and the protrusion and groove may be provided at a second side opposite the first side. To remove the tank from the body, the tank may be pulled near the magnet to detach the tank at the magnet, and the tank may be rotated at a point on the second side.
