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.
