Abstract
A vacuum cleaner assembly including a motor housing, a motor and fan assembly mounted in the motor housing, and a dirt containment chamber having an air intake at one end. An apertured wall is provided at one end of the motor housing so that the fan is closely adjacent the aperture. A planar filter is provided within the containment chamber and extends from a distal end to a proximal end of the chamber to separate the chamber into an air flow chamber and a dirt chamber. The aperture is separated from air flow communication with said intake opening by the filter.
