Claims20
A hand vacuum cleaner comprising:
- (a) an air flow path extending from a dirty air inlet to a clean air outlet;
- (b) a cyclone assembly positioned in the air flow path, the cyclone assembly comprising a cyclone chamber and a dirt collection chamber having an openable end wherein, when the hand vacuum cleaner is positioned with the dirty air inlet positioned at an upper end of the hand vacuum cleaner, a cyclone axis of rotation extends vertically and the openable end of the dirt collection chamber comprises a lower end of the dirt collection chamber which, when in an open position, is attached as part of the hand vacuum cleaner;
- (c) a main body housing a suction motor positioned in the air flow path;
- and,
- (d) a handle provided on the main body;
- wherein the cyclone chamber has a diameter in a direction that is transverse to the cyclone axis of rotation and a portion of the dirt collection chamber that is positioned below the cyclone chamber has a diameter in the direction that is greater than the diameter of the cyclone chamber.

A hand vacuum cleaner comprising:
- (a) an air flow path extending from a dirty air inlet to a clean air outlet wherein the dirty air inlet comprises an inlet conduit that extends rearwardly and has an axis that extends in a forward/rearward direction;
- (b) an air treatment member positioned in the air flow path, the air treatment member comprising an air treatment chamber and a dirt collection chamber having an openable end wherein, when the hand vacuum cleaner is positioned with the dirty air inlet positioned at an upper end of the hand vacuum cleaner, the openable end of the dirt collection chamber comprises a lower end of the dirt collection chamber which, when in an open position, is attached as part of the hand vacuum cleaner;
- (c) a main body housing a suction motor positioned in the air flow path;
- and,
- (d) a handle provided on the main body;
- wherein the air treatment chamber has a diameter in the forward/rearward direction and a portion of the dirt collection chamber that is positioned below the air treatment chamber has a diameter in the forward/rearward direction that is greater than the diameter of the air treatment chamber.
