Vacuum cleaner.

摘要

A cordless vacuum cleaner (12) having a dust bowl (26) is provided with a power brush attachment (14) comprising a cylindrical brush (56) and an electrical motor (58). Co-operating electrical contacts (42, 42', 76, 76') in the power brush attachment (14) and the dust bowl (26) connect the electric motor (58) in the power brush attachment (14) for concerted operation with a vacuum cleaner motor (122) in the cordless vacuum cleaner (12). Co-operating latch members (92, 86) in the dust bowl (26) and the power brush attachment (14) enable snapping the two elements together and facilitate their separation. Clam-shell construction of the power brush attachment (14) is utilized to accept parts of the latch members (92) and a contact retainer supporting both electrical contacts (76, 76') for application of power from the cordless vacuum cleaner (12) to the power brush attachment (14). An integrated base (184) provides means for retaining both the cordless vacuum cleaner (12) and the power brush attachment (14).
