ABSTRACT:
A cordless vacuum cleaner includes provision for snap-on attachment of a power brush to a rigid dust bowl thereof. Cooperating electrical contacts in the power brush and the dust bowl connect a brush motor in the power brush for concerted operation with a vacuum cleaner motor in the cordless vacuum cleaner. Cooperating latch members in the dust bowl and the power brush enable snapping the two elements together and facilitate their separation. Clam-shell construction is utilized to accept parts of the latch members and a contact retainer suppporting both electrical contacts for application of power from the cordless vacuum cleaner to the power brush. An integrated base provides means for retaining both the cordless vacuum cleaner and the power brush attachment.
