PROBLEM TO BE SOLVED: To prevent decrease in a quantity of sucked air, temperature elevation of a motor-driven air blower and the like by preventing a filter from being clogged by sticking fine dust or the like which is not separated from air onto the filter in a vacuum cleaner which adopts a cyclone scheme for centrifugally separating and accumulating dust sucked into a dust chamber together with air. SOLUTION: The filter provided in the dust chamber is integrally equipped with blades, and the filter is rotated by blowing sucked air onto the blades. The fine dust or the like stuck on the filter is blown away by a centrifugal force resulting therefrom, and the fine dust or the like floating in the dust chamber is prevented from sticking on the filter by the rotating blades.
