Abstract

A surface cleaning head may include a fluid distributor configured to distribute a cleaning fluid, an agitator configured to absorb at least a portion of the distributed cleaning fluid and to agitate debris on the surface to be cleaned, a fluid stripper configured to remove, from the agitator, at least a portion of the distributed cleaning fluid absorbed by the agitator, a debris container, and a removable cover. The debris container may include a solid debris chamber and a fluid debris chamber. The removable cover may include a fluid catch plate configured to transfer at least a portion of the cleaning fluid removed from the agitator by the fluid stripper to the fluid debris chamber, the fluid catch plate being configured to selectively transition between an in-use position and a cleaning position when the removable cover is removed from the surface cleaning head.

First claim

What is claimed is:

1. A surface cleaning device comprising:
an upright section; and
a surface cleaning head pivotally coupled to the upright section, the surface cleaning head including:
a fluid distributor configured to distribute a cleaning fluid;
an agitator configured to absorb at least a portion of the cleaning fluid distributed by the fluid distributor and to agitate debris on the surface to be cleaned;
a fluid stripper configured to remove, from the agitator, at least a portion of the distributed cleaning fluid absorbed by the agitator;
a debris container including:
a solid debris chamber configured to collect at least a portion of the debris agitated from the surface to be cleaned; and
a fluid debris chamber configured to collect at least a portion of the fluid removed from the agitator by the fluid stripper; and

a removable cover extending over at least a portion of the debris container and at least a portion of the agitator, the removable cover including a fluid catch plate pivotably coupled thereto and configured to transfer at least a portion of the cleaning fluid removed from the agitator by the fluid stripper to the fluid debris chamber, the fluid catch plate being configured to selectively and pivotably transition between an in-use position and a cleaning position when the removable cover is removed from the surface cleaning head.

2. The surface cleaning device of claim 1 , wherein the fluid catch plate includes a collecting region, a first channel, and a second channel, the collecting region being disposed forwardly of the first channel and the second channel.

3. The surface cleaning device of claim 2 , wherein the fluid catch plate includes a fluid diverter extending between the first channel and the second channel.

4. The surface cleaning device of claim 3 , wherein the fluid catch plate includes a first fluid grate extending between the first channel and the collecting region and a second fluid grate extending between the second channel and the collecting region.

5. The surface cleaning device of claim 1 , wherein the debris container includes a fluid collection tray fluidly coupled to the fluid catch plate and a container valve disposed within the fluid collection tray, the container valve configured to selectively fluidly couple the fluid collection tray with the fluid debris chamber.

6. The surface cleaning device of claim 5 , wherein the container valve is configured to transition between an open position and a closed position based on a state of engagement of the surface cleaning head with the surface to be cleaned.

7. The surface cleaning device of claim 6 , wherein the container valve is biased towards the closed position.

8. The surface cleaning device of claim 1 further comprising a multi-axis pivot joint pivotally coupling the upright section to the surface cleaning head, wherein the multi-axis pivot joint is configured such that the upright section is pivotable about at least a recline axis and a side-to-side pivot axis.

9. The surface cleaning device of claim 8 , wherein the multi-axis pivot joint includes a pivot body and a paddle pivotally coupled to the pivot body, the paddle being configured to pivot between a locked position and an unlocked position, the paddle pivoting between the locked position and the unlocked position based on a rotational position of the upright section about the recline axis.

10. The surface cleaning device of claim 9 , wherein, in the locked position, the paddle is configured to substantially prevent the upright section from pivoting about the side-to-side pivot axis and, in the unlocked position, the paddle does not substantially interfere with movement of the upright section about the side-to-side pivot axis.

11. The surface cleaning device of claim 10 , wherein the paddle includes a retaining portion and a triggering portion, the retaining portion being configured to selectively engage a portion of the upright section to substantially prevent the upright section from pivoting about the side-to-side pivot axis and the triggering portion being configured to engage with a portion of the surface cleaning head.

12. The surface cleaning device of claim 1 , wherein the fluid distributor includes at least one of a spray nozzle or a steam manifold.

13. A surface cleaning head comprising:
a fluid distributor configured to distribute a cleaning fluid;
an agitator configured to absorb at least a portion of the cleaning fluid distributed by the fluid distributor and to agitate debris on the surface to be cleaned;
a fluid stripper configured to remove, from the agitator, at least a portion of the distributed cleaning fluid absorbed by the agitator;
a debris container including:
a solid debris chamber configured to collect at least a portion of the debris agitated from the surface to be cleaned; and
a fluid debris chamber configured to collect at least a portion of the fluid removed from the agitator by the fluid stripper; and

a removable cover extending over at least a portion of the debris container and at least a portion of the agitator, the removable cover including a fluid catch plate pivotably coupled thereto and configured to transfer at least a portion of the cleaning fluid removed from the agitator by the fluid stripper to the fluid debris chamber, the fluid catch plate being configured to selectively and pivotably transition between an in-use position and a cleaning position when the removable cover is removed from the surface cleaning head.

14. The surface cleaning head of claim 13 , wherein the fluid catch plate includes a collecting region, a first channel, a second channel, and a fluid diverter extending between the first channel and the second channel, the collecting region being disposed forwardly of the first channel and the second channel.

15. The surface cleaning head of claim 14 , wherein the fluid catch plate includes a first fluid grate extending between the first channel and the collecting region and a second fluid grate extending between the second channel and the collecting region.

16. The surface cleaning head of claim 13 , wherein the debris container includes a fluid collection tray fluidly coupled to the fluid catch plate and a container valve disposed within the fluid collection tray, the container valve configured to selectively fluidly couple the fluid collection tray with the fluid debris chamber.

17. The surface cleaning head of claim 16 , wherein the container valve is configured to transition between an open position and a closed position based on a state of engagement of the surface cleaning head with the surface to be cleaned, the container valve being biased towards the closed position.

18. The surface cleaning head of claim 13 , wherein the fluid distributor includes at least one of a spray nozzle or a steam manifold.

19. A surface cleaning device comprising:
an upright section; and
a surface cleaning head pivotally coupled to the upright section, the surface cleaning head including:
a fluid distributor configured to distribute a cleaning fluid;
an agitator configured to absorb at least a portion of the cleaning fluid distributed by the fluid distributor and to agitate debris on the surface to be cleaned;
a fluid stripper configured to remove, from the agitator, at least a portion of the distributed cleaning fluid absorbed by the agitator;
a debris container including:
a solid debris chamber configured to collect at least a portion of the debris agitated from the surface to be cleaned; and
a fluid debris chamber configured to c
