Abstract

A surface cleaning apparatus with a removable compartment is provided that allows a dust cup in the removable compartment to be emptied while minimizing handling by the user. The removable compartment is removably secured within the surface cleaning apparatus. The removable compartment can be removed by activating a first trigger device. The dust cup can be emptied by activating a second trigger device.

Claims

1. A surface cleaning apparatus, comprising:

a body including a forward compartment;

a rotatable brush located in the forward compartment;

a motor configured to drive the rotatable brush;

a rearwardly inclined wall behind the rotatable brush, the rearwardly inclined wall being configured such that debris is propelled up the wall due to rotation of the rotatable brush;

a removable compartment behind the rotatable brush, the compartment comprising a dust cup and a dust removal door, the removable compartment being removably secured within the body by a securing structure;

a handle coupled to the body;

a first trigger device operably connected to the securing structure and configured to release the removable compartment to allow removal of the compartment from the body; and

a second trigger device configured to open the dust removal door.

2. The surface cleaning apparatus of claim 1, wherein the handle is coupled to the removable compartment and is configured to allow the removable compartment to be lifted out of the body with the handle.

3. The surface cleaning apparatus of claim 1, wherein the second trigger device is operably connected to the dust removal door by a cable.

4. The surface cleaning apparatus of claim 1, wherein the handle is coupled to the removable compartment and is configured to be used to steer the apparatus.

5. The surface cleaning apparatus of claim 1, wherein a bottom of the removable compartment is positioned lower than a top of the rearwardly inclined wall.

6. A surface cleaning apparatus comprising:

a body including a forward compartment;

a rotatable brush located in the forward compartment;

a motor configured to drive the rotatable brush;

a rearwardly inclined wall behind the rotatable brush;

a removable compartment behind the rotatable brush comprising a dust cup and a dust removal door, the removable compartment being removably secured within the body by a securing structure;

a handle coupled to the removable compartment when the removable compartment is removed from the body, and the handle being configured to be used to steer the apparatus when the removable compartment is attached to the body;

a first trigger device operably connected to the securing structure and configured to release the compartment to allow removal of the compartment; and

a second trigger device configured to allow opening of the dust removal door, wherein movement of the second trigger device in a first direction opens the dust removal door and movement of the second trigger device in a second direction closes the dust removal door.

7. The surface cleaning apparatus of claim 6, wherein the handle is configured to allow for removal of the compartment from the body.

8. The surface cleaning apparatus of claim 6, wherein a bottom of the removable compartment is positioned lower than a top of the rearwardly inclined wall.

9. A surface cleaning apparatus, comprising:

a body;

an elongated rotatable brush contained within the body;

a motor for driving the rotatable brush;

a rearwardly inclined wall behind the rotatable brush, the rearwardly inclined wall being configured such that debris is propelled up the wall due to rotation of the elongated rotatable brush;

a removable compartment behind the rearwardly inclined wall comprising a dust cup and a dust removal door, the removable compartment being removably secured within the body by a securing structure;

a handle coupled to the removable compartment;

a first trigger device operably connected to the securing structure for releasing the removable compartment to allow removal of the removable compartment from the body; and

a second trigger device for opening the dust removal door.

10. The surface cleaning apparatus of claim 9, wherein the first trigger device comprises a lever, a pedal, a switch, or a button.

11. The surface cleaning apparatus of claim 9, wherein the securing structure comprises a flange or a tab.

12. The surface cleaning apparatus of claim 11, wherein the securing structure is located on the removable compartment.

13. The surface cleaning apparatus of claim 9, wherein the second trigger device comprises a lever, a pedal, a switch, or a button.

14. The surface cleaning apparatus of claim 9, wherein the second trigger device is located on the handle.

15. The surface cleaning apparatus of claim 9, wherein the second trigger device is located on the removable compartment.

16. The surface cleaning apparatus of claim 9, wherein the body comprises a plurality of compartments, the removable compartment being an intermediate compartment.

17. The surface cleaning apparatus of claim 9, wherein a bottom of the removable compartment is positioned lower than a top of the rearwardly inclined wall.

18. The surface cleaning apparatus of claim 9, wherein the handle is configured to allow the removable compartment to be lifted out of the body with the handle.

19. The surface cleaning apparatus of claim 9, wherein the handle is configured to be used to steer the apparatus.

20. A surface cleaning apparatus comprising:

a body comprising a front section, an intermediate second and a rear section;
