Abstract

A surface cleaning apparatus, wherein the pre-motor filter dirt chamber is removable from the surface cleaning apparatus.

Claims

1. A surface cleaning apparatus comprising:

(a) a cyclone chamber having a first end having a first end wall, a second end having a second end wall, an air inlet, an air outlet and a sidewall;

(b) an air flow path extending from a dirty air inlet to a clean air outlet and including a suction motor and the cyclone chamber;

(c) a dirt collection chamber in communication with a dirt outlet of the cyclone chamber; and

,

(d) a pre-motor filter positioned in the air flow path downstream from the cyclone chamber and a pre-motor filter dirt chamber, wherein the pre-motor filter dirt chamber is removable from the surface cleaning apparatus, and wherein the pre-motor filter dirt chamber is openable concurrently with the dirt collection chamber.

2. The surface cleaning apparatus of claim 1 wherein the pre-motor filter dirt chamber is removable with the dirt collection chamber.

3. The surface cleaning apparatus of claim 2 wherein the cyclone chamber is removable from the surface cleaning apparatus and the pre-motor filter dirt chamber is also removable with the cyclone chamber.

4. The surface cleaning apparatus of claim 3 wherein the pre-motor filter dirt chamber is openable concurrently with the dirt collection chamber and the cyclone chamber.

5. The surface cleaning apparatus of claim 2 wherein the dirt collection chamber and the pre-motor filter dirt chamber are each positioned exterior to the cyclone chamber.

6. The surface cleaning apparatus of claim 5 wherein the pre-motor filter dirt chamber and the dirt collection chamber are concurrently openable.

7. The surface cleaning apparatus of claim 1 wherein the cyclone chamber is removable from the surface cleaning apparatus and the pre-motor filter dirt chamber is removable from the surface cleaning apparatus with the cyclone chamber.

8. The surface cleaning apparatus of claim 1 wherein the pre-motor filter dirt chamber is positioned whereby dirt travels from the pre-motor filter to the pre-motor filter dirt chamber under the influence of gravity.

9. The surface cleaning apparatus of claim 8 further comprising an agitation member operatively connected to the pre-motor filter.

10. The surface cleaning apparatus of claim 9 wherein the agitation member is actuated when the pre-motor filter dirt chamber is opened.

11. The surface cleaning apparatus of claim 9 wherein the agitation member is actuated when the pre-motor filter dirt chamber is removed from the surface cleaning apparatus.

12. The surface cleaning apparatus of claim 1 wherein the pre-motor filter dirt chamber is in communication with the pre-motor filter via the air outlet.

13. The surface cleaning apparatus of claim 12 wherein the air outlet comprises a vortex finder, the pre-motor filter dirt chamber is aligned with and spaced from the vortex finder to define an open area therebetween and a screen encloses the open area.

14. The surface cleaning apparatus of claim 13 wherein the pre-motor filter dirt chamber extends inwardly from the first end wall and the vortex finder extends inwardly from the second end wall and the air inlet is provided at the first end.

15. The surface cleaning apparatus of claim 1 wherein the pre-motor filter dirt chamber is positioned interior of the cyclone chamber and the pre-motor filter dirt chamber and the cyclone chamber are concurrently openable.

16. The surface cleaning apparatus of claim 1 wherein the pre-motor filter is located proximate the first end wall of the cyclone chamber and the pre-motor filter dirt chamber is located proximate the second end wall of the cyclone chamber.

17. A surface cleaning apparatus comprising:

(a) a cyclone chamber having a first end having a first end wall, a second end having a second end wall, an air inlet, an air outlet and a sidewall;

(b) an air flow path extending from a dirt air inlet to a clean air outlet and including a suction motor and the cyclone chamber; and

,

(c) a pre-motor filter positioned in the air flow path downstream from the cyclone chamber and a pre-motor filter dirt chamber, wherein the pre-motor filter dirt chamber is removable from the surface cleaning apparatus

wherein the pre-motor filter dirt chamber is openable concurrently with the cyclone chamber.

18. A surface cleaning apparatus comprising

(a) a cyclone chamber having a first end having a first end wall, a second end having a second end wall, an air inlet, an air outlet and a sidewall;

(b) an air flow path extending from a dirt air inlet to a clean air outlet and including a suction motor and the cyclone chamber;

(c) a pre-motor filter positioned in the air flow path downstream from the cyclone chamber and a pre-motor filter dirt chamber, wherein the pre-motor filter dirt chamber is removable from the surface cleaning apparatus; and

(d) an agitation member operatively connected to the pre-motor filter wherein the agitation member is actuated when either the pre-motor filter dirt chamber is opened or when the pre-motor filter dirt chamber is removed from the surface cleaning apparatus.

19. The surface cleaning apparatus of claim 18 wherein the agitation member is actuated when the pre-motor filter dirt chamber is opened.

20. The surface cleaning apparatus of claim 18 wherein the agitation member is actuated when the pre-motor filter dirt chamber is removed from the surface cleaning apparatus.
