ABSTRACT:
A handheld vacuum cleaner is provided that has a motor mounted with the rotational axis of its shaft parallel to the rotational axis of the rotating brush. The vacuum cleaner motor has an end bell, which is attached to the motor stator, and which holds a motor shaft bearing. The end bell is secured to the vacuum housing with an elastomeric mounting ring to dampen motor vibrations. The need for most motor mounting hardware is eliminated, because the housing supports the motor stator directly. The intake orifice of the vacuum is shaped to lie in two distinct planes, so that flat cleaning surfaces do not obstruct the orifice. The shape of the intake also allows one to clean immediately adjacent to a vertical wall.
