Abstract

An all in the head surface cleaning apparatus can include a surface cleaning head having an air flow path extending from a dirty air inlet to a clean air outlet. The surface cleaning head can include a cyclone assembly comprising a cyclone chamber and a dirt collection chamber. The cyclone chamber may have a longitudinal cyclone axis, a cyclone air inlet and a cyclone air outlet. The dirt collection chamber may be moveable between an in use position and an emptying position. The surface cleaning head may include a pre-motor filter chamber and a suction motor. At least one of the pre-motor filter and a pre-motor filter chamber may be visible when the dirt collection chamber is in the emptying position. An upper portion may be mounted to the surface cleaning head between a storage position and a floor cleaning position, and may include a drive handle.

Claims

1. An all in the head surface cleaning apparatus comprising:

(a) a surface cleaning head comprising;

(i) a front end, a rear end, first and second laterally opposed sidewalls and an air flow path extending from a dirty air inlet to a surface cleaning head air outlet;

(ii) a cyclone assembly comprising a cyclone chamber and a dirt collection chamber, the cyclone chamber having a longitudinal cyclone axis, a cyclone air inlet and a cyclone air outlet, the dirt collection chamber is moveable between an in use position and an emptying position;

(iii) a pre-motor filter chamber; and

,

(iv) a suction motor,

wherein at least one of the pre-motor filter and a pre-motor filter chamber is revealed when the dirt collection chamber is in the emptying position; and

(b) an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising a drive handle.

2. The apparatus of claim 1 wherein the pre-motor filter is positioned in the pre-motor filter chamber and the pre-motor filter chamber is moveable with the dirt collection chamber.

3. The apparatus of claim 2 wherein the pre-motor filter is moveable as a closed chamber.

4. The apparatus of claim 2 wherein the cyclone assembly is removable as a closed unit other than air inlet and air outlet ports and the dirt collection chamber is removed with the cyclone assembly.

5. The apparatus of claim 2 wherein the pre-motor filter chamber is integrally formed as part of the cyclone assembly.

6. The apparatus of claim 2 wherein the pre-motor filter chamber is located at an air outlet end of the cyclone assembly.

7. The apparatus of claim 2 wherein the pre-motor filter chamber has an air inlet and an air outlet, and the pre-motor filter has an upstream face, a downstream face and a pre-motor filter axis that is generally parallel to the upstream and/or downstream face and is generally transverse to the cyclone axis.

8. The apparatus of claim 2 wherein the pre-motor filter chamber has an air inlet and an air outlet, the suction motor has an air inlet end wherein a direction of flow through the pre-motor filter chamber air outlet is generally parallel with the suction motor housing air inlet when the dirt collection chamber is in the in use position.

9. The apparatus of claim 2 wherein the pre-motor filter chamber has an air inlet and an air outlet, the suction motor is provided in a suction motor housing having an air inlet and the pre-motor filter chamber air outlet abuts the suction motor housing air inlet when the dirt collection chamber is in the in use position and is spaced therefrom when the dirt collection chamber is in the emptying position.

10. The apparatus of claim 1 further comprising a brush motor drivingly connected to a moveable brushing member.

11. The apparatus of claim 1 wherein the dirt collection chamber comprises a portion of the cyclone chamber.

12. The apparatus of claim 1 wherein the dirt collection chamber is exterior to the cyclone chamber.

13. The apparatus of claim 1 wherein the pre-motor filter is positioned in the pre-motor filter chamber, the pre-motor filter chamber has an air inlet and an air outlet and the pre-motor chamber air outlet faces an air inlet of the suction motor.

14. The apparatus of claim 11 wherein the suction motor has a suction motor axis that is generally parallel to the cyclone axis and an upstream face of the pre-motor filter is generally transverse to the cyclone axis.

15. The apparatus of claim 1 wherein the pre-motor filter is positioned in the pre-motor filter chamber and the pre-motor filter chamber has an air inlet and an air outlet and the pre-motor chamber air inlet faces an air outlet of the cyclone chamber and the pre-motor filter chamber air inlet abuts the cyclone chamber air outlet when the dirt collection chamber is in the in use position and is spaced therefrom when the dirt collection chamber is in the emptying position.

16. The apparatus of claim 1 wherein the upper portion comprises a first end coupled to the surface cleaning head and a second end spaced apart from the first end and wherein the drive handle is disposed toward the second end.

17. The apparatus of claim 1 further comprising a mounting hub extending from the rear side of the surface cleaning head, the upper portion being moveably mounted to the mounting hub and being rotatably connected to the mounting hub whereby the upper portion is rotatable about a rotation axis relative to the surface cleaning head.
