PROBLEM TO BE SOLVED: To provide a vacuum cleaner capable of perfectly removing dust sticking to a filter. SOLUTION: The vacuum cleaner includes a nozzle and an air compressing/supplying mechanism that supplies compressed air to the nozzle and runs through a pressure difference between an atmospheric pressure and a negative pressure generated by rotations of a motor-driven blower. The compressed air from the nozzle is jetted to the filter to remove the dust lying on the filter. COPYRIGHT: (C)2009,JPO&INPIT
