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: Disclosed is a cleaner. A dust accommodation container according to an embodiment of the present invention comprises a winding member. The winding member rotates inside the dust accommodation container and winds thin, long compressible waste, such as animal hair or fibers, which have flowed into the dust accommodation container. Accordingly, the space occupied inside the dust accommodation container by waste such as hair or fibers is reduced. Thus, the dust accommodation container can accommodate a larger amount of waste, and the operable time of the cleaner is greater. Consequently, user convenience can be enhanced.

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.

Abstract: A cleaner is disclosed. A dust storage container according to an embodiment of the present invention includes a winding member. The winding member rotates in the dust storage container to wind debris having a shape which is thin, long, and compressible, such as fur of an animal or fiber introduced into the dust storage container. Accordingly, a space occupied by the debris in the form of fur or fiber in the dust storage container is reduced. Therefore, the dust storage container can receive a large amount of debris so as to increase an operable time of the cleaner. Consequently, the convenience of a user can be improved.
