Abstract:
An attachment for a vacuum cleaner comprising:a) a concave flexible member defining a chamber having an open end, the concave flexible member including a first port for communication with a vacuum from the vacuum cleaner;b) a coupling including an adaptor for engaging a hose of the vacuum cleaner;c) a rotor mounted in the coupling for rotation about a rotor axis normal to the open side, the rotor having a center of gravity eccentric to the rotor axis and a plurality of vanes;d) the coupling defining a first flow path for communication between the adaptor and the chamber through the first port;e) the coupling including a baffle between the first port and the rotor, the baffle cooperating to define a second flow path from the adaptor tangential is to the rotor;f) the coupling including a second port communicating with the atmosphere for supplying air to the second flow path; andg) the concave flexible member including a third port communicating with the atmosphere for supplying air to the first flow path.
