  • Patent number: 5586358
    Abstract: A hand held vacuum cleaner portable by a user during use is disclosed. The vacuum cleaner has a housing defining a main inlet, an accessory inlet, an exhaust outlet, and a vacuum passageway interconnecting the inlets to the outlet. An impeller is driven by a motor to create a stream of air passing downstream selectively from the main inlet or from the accessory inlet to the exhaust outlet. A cover is sealingly and selectively mountable over the main inlet and the accessory inlet for selecting a stream of air passing downstream from one of the main inlet or the accessory inlet. Also, the vacuum cleaner may have a pair of clip assemblies and a strap. The clip assemblies are ideally selectively positionable between a retracted position flush with the contours of the main housing of the vacuum cleaner and an extended position wherein the strap may be attached to the clip assemblies.
