Abstract: A cleaner includes a dust bin, a motor housing disposed above and coupled to the dust bin, a handle coupled to the motor housing, a cyclone part disposed in the dust bin and configured to separate dust from air, a filter disposed in the dust bin and configured to filter air having separated the dust through the cyclone part, and a compression part configured to compress the dust in the dust bin. The compression part includes an operating part disposed in the motor housing and configured to move in a space between an outer portion of the filter part and an inner circumferential surface of the dust bin, a manipulation part disposed outside the motor housing and configured to be manipulated to move the operating part, and a transmission part that is disposed in the motor housing and connects the operating part and the manipulation part.

Abstract: A nozzle for a cleaner includes a nozzle body having a suction passage in which air flows. A water tank is detachably mounted on the nozzle body, and a rotation cleaning part is rotatably supported at a lower side of the nozzle body to receive water from the water tank for cleaning a floor. The water tank includes an outlet through which water is discharged, a valve configured to open and close the outlet, and an air hole configured to introduce outside air into the water tank. An air hole operation part is movably installed on the water tank to open and close the air hole.
