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.
