ABSTRACT:
A vacuum cleaner having a rotor which is mounted to turn at the inside of a filter bag of the device, and which acts when turned to contact the bag and displace accumulated dust from its outer surface. The rotor may be actuable from the outside of the cleaner when a cover of the cleaner is in closed active condition. The rotor desirably includes one or more resiliently flexible arms which are deflectable to a reduced diameter condition by the bag when the bag is constricted inwardly against and about the rotor by the flow of suction air when the device is in use.
