Abstract

A portable surface cleaning apparatus, such as a hand vacuum cleaner, having a cyclone and a cleaner body, wherein a pre-motor filter is positioned in the air flow passage upstream from the suction motor and, when the cyclone and the cleaner body are separated, the pre-motor filter remains in position and access to the pre-motor filter is provided.

Claims

1. A portable surface cleaning apparatus comprising:

(a) an air flow passage extending from a dirty air inlet to a clean air outlet;

(b) a cleaner body housing;

(c) a suction motor positioned in the air flow passage, the suction motor having a motor axis and positioned in the cleaner body housing;

(d) a cyclone positioned in the air flow passage, the cyclone comprising an air inlet, an air outlet and a longitudinal axis, wherein the cyclone and cleaner body are separable; and

,

(e) a pre-motor filter positioned in the air flow passage upstream from the suction motor and having an upstream side and a downstream side wherein, when the cyclone and the cleaner body are separated, the pre-motor filter remains in position and access to the pre-motor filter is provided.

2. The portable surface cleaning apparatus of claim 1 wherein the cleaner body housing comprises a portion housing the pre-motor filter.

3. The portable surface cleaning apparatus of claim 2 wherein the pre-motor filter has an outer perimeter surface extending between the upstream and downstream sides and located within the cleaner body housing.

4. The portable surface cleaning apparatus of claim 3 wherein the outer perimeter surface is adjacent an inner surface of a portion of the sidewall of the cleaner body housing and the cleaner body housing further comprises a handle having a first end located on the portion of the sidewall of the cleaner body.

5. The portable surface cleaning apparatus of claim 1 wherein the longitudinal axis of the cyclone and the motor axis are generally parallel.

6. The portable surface cleaning apparatus of claim 1 wherein the upstream side of the pre-motor filter faces the cyclone air outlet.

7. The portable surface cleaning apparatus of claim 3 wherein the downstream side of the pre-motor filter faces the suction motor.

8. The portable surface cleaning apparatus of claim 7 wherein the cleaner body housing comprises a portion housing the pre-motor filter.

9. The portable surface cleaning apparatus of claim 1 wherein the longitudinal axis of the cyclone extends through the pre-motor filter.

10. The portable surface cleaning apparatus of claim 9 wherein the motor axis extends through the pre-motor filter.

11. The portable surface cleaning apparatus of claim 10 wherein the cleaner body housing comprises a portion housing the pro-motor filter.

12. The portable surface cleaning apparatus of claim 1 wherein the motor axis extends through the pre-motor filter.

13. The portable surface cleaning apparatus of claim 1 wherein the longitudinal axis of the cyclone is perpendicular to the upstream side of the pre-motor filter.

14. The portable surface cleaning apparatus of claim 13 wherein the motor axis is perpendicular to the downstream side of the pre-motor filter.

15. The portable surface cleaning apparatus of claim 1 wherein the motor axis is perpendicular to the downstream side of the pre-motor filter.

16. The portable surface cleaning apparatus of claim 1 wherein the cleaner body housing is provided with a handle and one end of the handle is positioned adjacent the clean air outlet and a second end of the handle is positioned adjacent the cyclone.

17. The portable surface cleaning apparatus of claim 1 wherein the cleaner body housing is provided with a handle and the handle extends generally in the same direction as the motor axis.

18. The portable surface cleaning apparatus of claim 1 wherein the pre-motor filter is symmetrical about the longitudinal axis of the cyclone.

19. The portable surface cleaning apparatus of claim 18 wherein the pre-motor filter is symmetrical about the motor axis.

20. The portable surface cleaning apparatus of claim 1 wherein the pre-motor filter is symmetrical about the motor axis.

21. The portable surface cleaning apparatus of claim 1 wherein the portable surface cleaning apparatus is a hand vacuum cleaner.
