-20. (canceled)
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;
- (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 downstream of the cyclone;
- (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 a hand grip portion of the pistol grip handle;
- and,
- (e) an energy storage unit located at a lower end of the pistol grip handle, wherein the cyclone assembly has a bottom wall that is openable whereby a dirt collection region of the cyclone assembly is emptiable when the bottom wall is opened.
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;
- (b) an air treatment assembly comprising an air treatment chamber that is positioned in the air flow path, the air treatment chamber having a front end, a rear end and a central longitudinal axis that extends centrally through the air treatment chamber between the front and rear ends of the air treatment chamber;
- (c) a main body housing a suction motor, the suction motor is positioned in the air flow path downstream of the air treatment chamber;
- (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 central longitudinal axis extends through a hand grip portion of the pistol grip handle;
- (e) an energy storage unit located at a lower end of the pistol grip handle,
- wherein the air treatment chamber has a bottom wall that is openable whereby a dirt collection region of the air treatment chamber is emptiable when the bottom wall is opened.
