Patent

CA 2192906

A vacuum cleaner with a floor traveling head having a housing, a rotatable brush, and two motors. The housing has a suction inlet with an entrance at its bottom and a separate pocket in the bottom of the housing for the rotatable brush. A wall of the housing separates the pocket from the suction inlet such that the entrance to the suction inlet has a relatively small area to maximize vacuum pull at the entrance. The suction inlet has a lower section with straight wall sections that are angled to form smaller areas at the lateral ends of the suction inlet. The suction inlet has an exit aperture directly into a collection assembly such that air velocity increases from the lower section to the upper section and then decreases from the upper section into the collection assembly.
