Abstract
The present disclosure relates to a vacuum cleaner for separating and collecting dust and other contaminants by using a multi-cyclone and a mesh filter, including a cleaning unit for sweeping dust and foreign materials attached to the mesh filter along an outer circumferential surface of the mesh filter, and a rotation unit coupled to the cleaning unit for rotating the cleaning unit relative to the mesh filter, whereby the cleaning unit can clean a surface of the filter automatically or manually during an operation of the cleaner, so that the filter surface can be kept clean, and a load on a fan unit caused due to foreign materials or dust can be reduced.
