Abstract

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

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; 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 openable and the pre-motor filter dirt chamber is contiguous with and exterior to the air flow path whereby air passing through the surface cleaning apparatus does not pass through the pre-motor filter dirt chamber.

2. The surface cleaning apparatus of claim 1 wherein the pre-motor filter dirt chamber is positioned interior of the cyclone chamber.

3. The surface cleaning apparatus of claim 2 wherein the wherein the pre-motor filter dirt chamber is in communication with the pre-motor filter via the air outlet.

4. The surface cleaning apparatus of claim 3 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.

5. The surface cleaning apparatus of claim 4 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.

6. The surface cleaning apparatus of claim 1 further comprising an agitation member operatively connected to the pre-motor filter.

7. The surface cleaning apparatus of claim 6 wherein the agitation member is actuated when the pre-motor filter dirt chamber is opened.

8. The surface cleaning apparatus of claim 1 further comprising a dirt collection chamber in communication with a dirt outlet of the cyclone chamber wherein the pre-motor filter dirt chamber is removable from the surface cleaning apparatus with the dirt collection chamber.

9. The surface cleaning apparatus of claim 8 wherein the pre-motor filter dirt chamber is also removable with the cyclone chamber.

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

11. The surface cleaning apparatus of claim 1 further comprising an agitation member operatively connected to the pre-motor filter wherein the pre-motor filter dirt chamber is removable from the surface cleaning apparatus and the agitation member is actuated when the pre-motor filter dirt chamber is removed from the surface cleaning apparatus.

12. 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 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 openable; and

(d) a dirt collection chamber in communication with a dirt outlet of the cyclone chamber and having a dirt collection surface moveable between a closed and an open position wherein the pre-motor filter dirt chamber is concurrently openable with the dirt collection surface.

13. The surface cleaning apparatus of claim 12 wherein the pre-motor filter dirt chamber and the dirt collection chamber have a common door.

14. The surface cleaning apparatus of claim 13 wherein the dirt collection chamber is positioned exterior to the cyclone chamber.

15. The surface cleaning apparatus of claim 13 wherein the pre-motor filter dirt chamber is positioned exterior to the cyclone chamber.

16. The surface cleaning apparatus of claim 15 wherein the pre-motor filter dirt chamber is also positioned exterior to the dirt collection chamber.

17. The surface cleaning apparatus of claim 12 wherein the pre-motor filter dirt chamber is also concurrently openable with the cyclone chamber.

18. The surface cleaning apparatus of claim 17 wherein the cyclone chamber, the pre-motor filter dirt chamber and the dirt collection chamber have a common door.

19. 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, a sidewall and a dirt collection surface moveable between a closed and an open position;

(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 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 openable; and

(d) wherein the pre-motor filter dirt chamber is concurrently openable with the dirt collection surface of the cyclone chamber.

20. The surface cleaning apparatus of claim 19 wherein the cyclone chamber and the pre-motor filter dirt chamber have a common door.
