A battery-powered vacuum cleaner that may be converted from a conventional on-the-floor cleaner to a portable canister cleaner for off-the-floor or on-the-floor cleaning operations. The vacuum cleaner has a filter chamber comprising a removable dirt cup having a substantially flat filter oriented in the direction of air flow. A fan and motor assembly is angularly related to the longitudinal axis of the vacuum cleaner to provide a lower profile of the cleaner housing while cleaning under low clearance objects. A handle is adjustable relative to the housing, or it may be removed to convert the cleaner to a portable canister.

[ What is claimed:] [1.]1. A vacuum cleaner comprising:an elongated canister defining a motor housing;a motor housing comprising an elongated casing having a longitudinal axis and an end wall;a motor and fan assembly mounted in said housing, said fan having an axis of rotation angularly related to said longitudinal axis so that said fan presents a circular envelope of rotation when viewed in the direction of its axis of rotation and presents an elliptical envelope of rotation when viewed in the direction of said longitudinal axis;an aperture defined by said end wall;an air duct between said fan and said end wall;a containment chamber having a proximal end removably attached to said end wall and a distal end defining an intake opening;a substantially planar filter within said containment chamber and extending from said distal end to said proximal end of said containment chamber to separate said containment chamber into an air flow chamber and a dirt chamber;said aperture being separated from air flow communication with said intake opening by said filter.
