Abstract
A hand vacuum cleaner has a cyclone having a cyclone axis of rotation that extends between the front and rear ends of the cyclone. A main body houses a suction motor. The suction motor is positioned at a lower end of the main body and forward of a battery pack provided at a lower end of a pistol grip handle.
Claims29
A hand vacuum cleaner having an upper end, a lower end, a front end having a dirty air inlet and a rear end, the hand vacuum cleaner comprising:
- (a) an air flow path extending from the dirty air inlet to a clean air outlet, the air flow path comprising an inlet conduit that is positioned at the upper end of the hand vacuum cleaner, the inlet conduit having a conduit axis;
- (b) a cyclone assembly positioned in the air flow path, the cyclone assembly comprising a cyclone having a front end, a rear end and a cyclone axis of rotation that extends between the front and rear ends of the cyclone;
- (c) a main body housing a suction motor, the suction motor is positioned in the air flow path and is positioned downstream of the cyclone, the suction motor has an axis of rotation;
- (d) a pistol grip handle located at the rear end of the hand vacuum cleaner wherein a finger grip area is positioned forward of the pistol grip handle and rearward of the main body, and wherein the cyclone axis of rotation extends through the pistol grip handle, and wherein the pistol grip handle is substantially perpendicular to the cyclone axis of rotation;
- and,
- (e) a first energy storage unit located at a lower end of the pistol grip handle;
- wherein the suction motor is located at the lower end of the hand vacuum cleaner and forward of the first energy storage unit.
