ABSTRACT:
A multi-function vacuum cleaner nozzle for attachment to the end of a vacuum cleaner hose. The device comprises a housing body (40), a dust brush (44), and two pivotal cleaning arms (6). Housing (40) has three ports (50), (52), and (54) extending therethrough, with port (50) and port (52) being adapted to receive a suction conduit (4). Port (52) is fitted with dust brush (44) which snaps into a recess (42) encircling said housing. Insertion of the conduit into port (52) selects the arms to receive suction air and substantially doses off port (50). Arms (6) are attached on the end of port (54) which is opposite port (52). Friction ridges (28) and (74) interact with each other, allowing several stable positions for arms (6). This makes the arms adjustable between upholstery, crevice, edge and corner tool positions. Insertion of said conduit into port (50) selects said dust brush to receive suction air and substantially closes off port (54).
