Abstract

A hand held surface cleaning apparatus has a fluid flow path extending from a dirty fluid inlet provided at a front end of the hand held surface cleaning apparatus to a clean air outlet, the fluid flow path including a separator and a suction motor, wherein the suction motor is positioned rearward of the dirty fluid inlet. A separation stage comprising the separator, a solid collection chamber in communication with a separated element outlet of the separator and a separated liquid reservoir in communication with the solid collection chamber is provided. The solid collection chamber is positioned rearward of the separated liquid reservoir and the separator is positioned rearward of the solid collection chamber.

First claim

The invention claimed is:

1. A hand held surface cleaning apparatus comprising:
a) a fluid flow path extending from a dirty fluid inlet provided at a front end of the hand held surface cleaning apparatus to a clean air outlet, the fluid flow path including a separator and a suction motor, wherein the suction motor is positioned rearward of the dirty fluid inlet;
b) a separation stage comprising the separator, a solid collection chamber in communication with a separated element outlet of the separator and a separated liquid reservoir in communication with the solid collection chamber wherein the solid collection chamber is positioned rearward of the separated liquid reservoir, the separator is positioned rearward of the solid collection chamber; and,
c) a handle.

2. The hand held surface cleaning apparatus of claim 1 , wherein the suction motor is positioned rearward of the separator.

3. The hand held surface cleaning apparatus of claim 2 , wherein the separated liquid reservoir is positioned at the front end.

4. The hand held surface cleaning apparatus of claim 2 , wherein the handle is provided at a rear end of the hand held surface cleaning apparatus.

5. The hand held surface cleaning apparatus of claim 1 , wherein a plane intersects the separated liquid reservoir, the solid collection chamber and the separator.

6. The hand held surface cleaning apparatus of claim 1 , wherein the fluid flow path includes an inlet passage that extends from the dirty fluid inlet to an inlet to the separator and a portion of the inlet passage extends through the separated liquid reservoir.

7. The hand held surface cleaning apparatus of claim 1 , wherein the fluid flow path includes a downstream portion extending from a separator outlet to the suction motor and the suction motor has an axis of rotation that is generally parallel to a flow axis of the downstream portion.

8. The hand held surface cleaning apparatus of claim 1 , wherein a flow axis of the downstream portion is generally parallel to a flow axis of the inlet passage.

9. The hand held surface cleaning apparatus of claim 1 , wherein the separator comprises an inverted cyclone comprising, when the surface cleaning apparatus is in a floor cleaning orientation, a lower end and an upper end, the lower end having a cyclone fluid inlet and a cyclone fluid outlet and the upper end having the separated element outlet.

10. The hand held surface cleaning apparatus of claim 9 , wherein the fluid flow path includes an inlet passage that extends from the dirty fluid inlet to an inlet to the cyclone and the cyclone has an axis of rotation that is generally perpendicular to a flow axis of the inlet passage.

11. The hand held surface cleaning apparatus of claim 1 , further comprising an on board power source wherein the on board power source is positioned rearward of the separator.

12. The hand held surface cleaning apparatus of claim 1 , further comprising an on board power source wherein the on board power source is positioned rearward of the suction motor.

13. The hand held surface cleaning apparatus of claim 1 , wherein the fluid flow path includes an inlet passage that extends from the dirty fluid inlet to an inlet to the separator and the hand held surface cleaning apparatus further comprises an on board power source wherein at least a portion of the on board power source is positioned above of the suction motor when a flow axis of the inlet passage extends generally horizontally.

14. The hand held surface cleaning apparatus of claim 1 , further comprising a cleaning solution delivery system comprising at least one spray nozzle that delivers at least one cleaning solution.

15. The hand held surface cleaning apparatus of claim 1 , wherein the handle extends from the separator to a position rearward of an inlet end of the suction motor.

16. The hand held surface cleaning apparatus of claim 1 , wherein the handle extends from the separator to a position adjacent a rear end of the suction motor.

17. The hand held surface cleaning apparatus of claim 1 , wherein the fluid flow path includes an inlet passage that extends from the dirty fluid inlet to an inlet to the separator and when a flow axis of the inlet passage extends generally horizontally, all operating components of the hand held surface cleaning apparatus are positioned below the separated element outlet.
