Abstract
A multi-use vacuum cleaner has a central body which houses a motor, air impeller, battery and a dirt collection chamber. One end of the central body has a face inclined to the longitudinal axis of the central body with a rectangular inlet orifice into which the coupling nozzle of a floor and carpet pickup head can be frictionally inserted. The other end of the body has an integral, axially protruding extension providing a primary handle for manipulating the body as a hand held cushion and upholstery cleaner. The primary handle has means for detachably mounting an extension handle permitting the unit to be used as a standard upright vacuum cleaner or for vacuuming overhead and other areas which would be otherwise inaccessible.
