Abstract

A vacuum cleaner comprises a cleaner head adapted for movement over a surface and having a dirty air inlet; a handle for moving the cleaner head over the surface; a cyclone chamber having a cyclonic flow region, a fluid inlet downstream from the dirty air inlet and a fluid outlet; a particle receiving chamber having a door and an outer wall; a plate positioned between the cyclone chamber and the particle receiving chamber; and, a motor for causing the air to flow through the vacuum cleaner from the dirty air inlet to a vacuum cleaner air outlet.

Claims

1. A vacuum cleaner comprising:

(a) a cleaner head adapted for movement over a surface and having a dirty air inlet;

(b) a handle for moving the cleaner head over the surface;

(c) a cyclone chamber having a cyclonic flow region, a fluid inlet downstream from the dirty air inlet and a fluid outlet;

(d) a particle receiving chamber having a door and an outer wall;

(e) a plate positioned between the cyclone chamber and the particle receiving chamber; and

,

(f) a motor for causing the air to flow through the vacuum cleaner from the dirty air inlet to a vacuum cleaner air outlet.

2. The vacuum cleaner of claim 1 wherein the door is provided in the outer wall.

3. The vacuum cleaner of claim 1 wherein the particle receiving chamber is disposed beneath the plate.

4. The vacuum cleaner of claim 1 wherein the particle receiving chamber is removably mounted to the vacuum cleaner.

5. The vacuum cleaner of claim 4 wherein the door is provided in the outer wall.

6. The vacuum cleaner of claim 4 wherein the particle receiving chamber is disposed beneath the plate.

7. The vacuum cleaner of claim 1 wherein the plate has a surface facing the cyclone chamber that is flat.

8. The vacuum cleaner of claim 1 wherein the vacuum cleaner is an upright vacuum cleaner having a main casing and the plate is horizontally disposed when the main casing is in an upright storage position.

9. The vacuum cleaner of claim 1 wherein the plate comprises a plurality of apertures.
