ABSTRACT:
A filter cleaning device for a cyclone vacuum cleaner which comprises a cyclone body having a suction port and a discharge port, a dust collecting receptacle connected to the cyclone body for collecting dusts separated from air drawn in through the suction port, and a filter connected to the discharge port and disposed inside the dust collecting receptacle. The filter cleaning device includes a manipulation unit disposed under the filter to approach to, and retreat from the filter. A connection member is interposed between the manipulation unit and the dust-removing ring for moving the dust-removing ring in association with the approaching and retreating movements of the manipulation unit. An elastic spring is interposed between the filter and the manipulation unit for urging the manipulation unit to retreat from the filter.
