Abstract
A vacuum accessory tool comprises a nozzle body defining an interior, with an opening formed in the nozzle body and a working air conduit provided on the nozzle body in fluid communication with the opening via the interior. A hair removal assembly is associated with the nozzle body, and can include nubs from a flexible polymeric material adapted to generate an electrostatic charge when the tool moves over and in contact with a carpet surface.
Claims19
A vacuum accessory tool comprising:
- a nozzle body defining an interior;
- an opening formed in the nozzle body and adapted to be connected to a suction source remote from the nozzle body for generating a working air flow through the interior of the nozzle body;
- a working air conduit provided on the nozzle body in fluid communication with the opening via the interior, wherein the working air conduit is adapted to be connected to a flexible hose to connect the open to the suction source remote from the nozzle body;
- a molded cup-like body secured to and enclosing a forward end of the nozzle body and comprising a base and a plurality of nubs extending from the base, wherein a portion of the base forms a rounded forward end of the cup-like body;
- and
- at least one suction nozzle opening formed through the cup-like body and in fluid communication with the working air conduit;
- wherein at least the nubs are formed of a flexible polymeric material adapted to generate an electrostatic charge when the tool moves over and in contact with a carpet surface.
