Abstract

A hand vacuum cleaner is provided with a wand mounted to the dirty fluid inlet of the hand vacuum cleaner and the wand has a distal inlet that is mounted on a surface cleaning head. The hand vacuum cleaner has a cyclonic cleaning stage and the fluid flow motor is displaced vertically with respect to dirty fluid inlet.

Claims

1. A hand vacuum cleaner comprising:

a) a main body comprising a fluid flow motor;

b) a first cyclonic cleaning stage comprising a cyclone chamber, the cyclone chamber having first and second spaced apart ends, a dirty fluid inlet, a clean fluid outlet and a first longitudinal axis, the dirty fluid inlet defines a passage extending along a passage axis that intersects the first longitudinal axis;

c) a handle comprising a portion that extends upwardly when the hand vacuum cleaner is positioned on a horizontal surface; and

,

d) a wand mounted to the dirty fluid inlet, the wand having a distal inlet that is mounted on a surface cleaning head

wherein the fluid flow motor is displaced from the passage axis in a direction parallel to the longitudinal axis.

2. The hand vacuum cleaner of claim 1 wherein the first end of the cyclone chamber is positioned above the second end of the cyclone chamber when the hand vacuum cleaner is positioned on a horizontal surface, and the fluid flow motor is positioned above the first end of the cyclone chamber when the hand vacuum cleaner is positioned on the horizontal surface.

3. A hand vacuum cleaner comprising:

a) a main body comprising a fluid flow motor;

b) a first cyclonic cleaning stage having first and second spaced apart ends and comprising a cyclone chamber, the cyclone chamber having first and second spaced apart ends, a dirty fluid inlet and a clean fluid outlet, wherein the first end of the cyclone chamber is positioned above the second end of the cyclone chamber when the hand vacuum cleaner is positioned on a horizontal surface; and

,

c) a handle comprising a portion that extends upwardly when the hand vacuum cleaner is positioned on a horizontal surface; and

,

d) a wand mounted to the dirty fluid inlet, the wand having a distal inlet that is mounted on a surface cleaning head.

4. The hand vacuum cleaner of claim 3 wherein an end of the handle is mounted to the hand vacuum cleaner at a position adjacent an upper end of the first cyclonic cleaning stage.

5. The hand vacuum cleaner of claim 3 wherein the dirty fluid inlet defines a passage extending along a passage axis, wherein the passage axis intersects the handle.

6. The hand vacuum cleaner of claim 4 wherein the hand vacuum cleaner has a lower dirt collection region, the cyclone chamber of the first cyclonic cleaning stage extends above the dirt collection region and the end of the handle is an upper end of the handle.

7. The hand vacuum cleaner of claim 3 wherein the first cyclonic cleaning stage comprises a dirt collection region that has a pivotally openable bottom.

8. The hand vacuum cleaner of claim 7 wherein the bottom is openable when the dirt collection region is attached to the main body.

9. The hand vacuum cleaner of claim 3 wherein the dirty fluid inlet and the clean fluid outlet are located at the first end of the cyclone chamber, the first cyclonic cleaning stage comprises a dirt collection region, and the dirt collection region is located at the second end of the first cyclonic cleaning stage.

10. The hand vacuum cleaner of claim 9 wherein the dirty fluid inlet defines a passage extending along a passage axis, wherein the passage axis intersects the handle.

11. The hand vacuum cleaner of claim 10 wherein the dirt collection region has a pivotally openable bottom.

12. The hand vacuum cleaner of claim 3 wherein the portion extends away from a fluid flow motor housing of the main body.

13. The hand vacuum cleaner of claim 3 wherein the dirty fluid inlet defines a passage extending along a passage axis, wherein the passage axis intersects the portion of the handle that extends upwardly.

14. The hand vacuum cleaner of claim 3 wherein the cyclone chamber extends longitudinally along a first longitudinal axis, the dirty fluid inlet defines a passage extending along a passage axis that intersects the first longitudinal axis, and the fluid flow motor is displaced from the passage axis in a direction parallel to the longitudinal axis.

15. The hand vacuum cleaner of claim 14 wherein the fluid flow motor has a fluid flow motor axis that is parallel to the passage axis.

16. The hand vacuum cleaner of claim 15 wherein the fluid flow motor axis is displaced from the passage axis in a direction parallel to the longitudinal axis.

17. The hand vacuum cleaner of claim 3 wherein the cyclone chamber extends longitudinally along a first longitudinal axis, the dirty fluid inlet defines a passage extending along a passage axis and the fluid flow motor extends transverse to the first longitudinal axis, is parallel to the passage axis and is displaced from the passage axis in a direction parallel to the longitudinal axis.

18. The hand vacuum cleaner of claim 17 wherein the dirty fluid inlet of the cyclone chamber is located at a front end of the hand vacuum cleaner and the fluid flow motor is positioned rearward of the first cyclonic cleaning stage.

19. The hand vacuum cleaner of claim 3 wherein the dirty fluid inlet of the cyclone chamber is located at a front end of the hand vacuum cleaner and the fluid flow motor is positioned rearward of the first cyclonic cleaning stage.

20. The hand vacuum cleaner of claim 3 wherein the first cyclonic cleaning stage comprises a dirt collection region and the dirt collection region is positioned below the wand when the hand vacuum cleaner is positioned on a horizontal surface.

21. The hand vacuum cleaner of claim 3 further comprising a second cyclonic cleaning stage comprising a plurality of cyclones, each cyclone of the plurality of cyclones has an fluid inlet and the fluid inlets of the plurality of cyclones are provided at the first end of the second cyclonic cleaning stage wherein, when the hand vacuum cleaner is positioned on a horizontal surface, the first end of the second cyclonic cleaning stage is positioned above the first end of the first cyclonic cleaning stage and above the wand.

22. The hand vacuum cleaner of claim 3 wherein, when the hand vacuum cleaner is positioned on a horizontal surface, a first end of a second cyclonic cleaning stage is positioned above a second end of the second cyclonic cleaning stage and the first end of the second cyclonic cleaning stage is positioned above the first end of the cyclone chamber.

23. The hand vacuum cleaner of claim 3 further comprising a dirt collection region which is removably mounted to the hand vacuum cleaner.

24. The hand vacuum cleaner of claim 3 wherein the fluid flow motor has a fluid flow motor axis, the dirty fluid inlet defines a passage extending along a passage axis and a flow path from a pre-motor filter to the fluid flow motor comprises a portion that is parallel to the fluid flow motor axis and is spaced from the passage axis.
