Abstract: The present disclosure relates to a cleaner capable of easily separating a filter module from a main body of the cleaner and separating and assembling the separated filter module again. Disclosed is a cleaner including: a main body; a suction motor disposed in the main body and configured to generate a suction force so as to suction air; a dust separator separating dust from air by generating a cyclone flow in air introduced by the suction motor; and a filter module having a filter for filtering air discharged from the suction motor and being detachable from the main body. Here, the filter module is configured to be easily separated from the main body of the cleaner and assembled, such that the filter disposed inside the filter module may be easily cleaned or replaced.

Abstract: A cleaner includes a suction unit, a main body including a cyclone unit for separating dust from air suctioned through the suction unit, and a dust container that stores dust separated in the cyclone unit below the cyclone unit. A filter unit is disposed inside the cyclone unit for filtering the air, and a movable unit disposed inside the cyclone unit includes a cleaning part for cleaning the outer circumference of the filter unit. An operation unit disposed outside the main body moves the movable unit and the cleaning part to remove dust from the outer surface of the filter unit.

Abstract: Provided is a vacuum cleaner separating and collecting dust, or the like, using a multi-cyclone and mesh filter. The vacuum cleaner includes a cleaning unit sweeping dust and foreign objects clinging on the mesh filter down along an outer circumferential surface of the mesh filter and a rotary unit coupled to the mesh filter and relatively rotating the mesh filter with respect to the cleaning unit. Since the cleaning unit automatically/manually cleans a surface of the filter during an operation of the cleaner, the surface of the filter may be maintained to be clean and a load applied to a fan unit due to a foreign object or dust may be reduced.
