Abstract
A hand vacuum cleaner has an upper end, a lower end, an air flow passage, a main body with a handle, an air treatment chamber and a suction motor. The air treatment chamber has an air outlet, the air outlet comprising a rigid porous member and a filter media that is removably positionable in the rigid porous member. The air treatment chamber is moveable to an open position in which the air treatment chamber is emptyable, and the rigid porous member is moveable within the air treatment chamber to an open position in which the filter media is removable.
Claims20
A vacuum cleaner comprising:
- (a) an air flow passage extending from a dirty air inlet to a clean air outlet;
- (b) an air treatment chamber positioned in the air flow passage downstream from the dirty air inlet, the air treatment chamber defining a volume and comprising an air inlet and an air outlet, the air outlet comprising a rigid porous member and a filter media that is removably positionable in the rigid porous member;
- and,
- (c) a suction motor provided in the air flow passage wherein the air treatment chamber is moveable to an open position in which the air treatment chamber is emptyable, and the rigid porous member is moveable within the air treatment chamber to an open position in which the filter media is removable.
A vacuum cleaner comprising:
- (a) an air flow passage extending from a dirty air inlet to a clean air outlet;
- (b) an air treatment chamber positioned in the air flow passage downstream from the dirty air inlet, the air treatment chamber defining a volume and comprising an air inlet and an air outlet, the air outlet comprising a rigid porous member;
- (c) a pre-motor filter housing wherein a pre-motor filter media is positionable in the pre-motor filter housing;
- and,
- (d) a suction motor provided in the air flow passage
- wherein the air treatment chamber is moveable to an open position in which the air treatment chamber is emptyable, and the rigid porous member is moveable within the air treatment chamber to an open position in which the pre-motor filter housing is opened.
