Abstract

A surface cleaning apparatus has a steam distribution manifold located along the leading edge of a foot assembly and configured to apply steam to a surface to be cleaned, in front of the cleaning pad. The cleaning pad trailing the manifold can absorb soil, stains and residual moisture from the cleaning process as the steam appliance is moved across the surface to be cleaned. The cleaning pad can comprise a superabsorbent material. In another embodiment, the cleaning pad can comprise a melamine foam with abrasive particles interspersed therein and configured to agitate the surface to be cleaned in conjunction with steam.

First claim

What is claimed is:

1. A surface cleaning apparatus comprising:
a foot movable along a surface to be cleaned and comprising a frame;
a handle coupled to the foot for maneuvering the foot along the surface to be cleaned;
a cleaning pad adjacent to a lower surface of the foot and positioned to contact the surface to be cleaned;
a steam generator provided on one of the foot or the handle for producing steam; and
a steam distribution manifold pivotally mounted to the frame along a front of the foot and comprising at least one steam outlet in fluid communication with the steam generator to deliver steam to the surface to be cleaned;
wherein the steam distribution manifold is movable about the frame between a first position for applying steam to the surface to be cleaned and a second position in which the steam distribution manifold is raised with respect to the first position; and
wherein the frame is configured to remain on the surface to be cleaned when the steam distribution manifold is in the first and second positions.

2. The surface cleaning apparatus according to claim 1 , wherein the cleaning pad is positioned rearwardly of the steam distribution manifold, such that the cleaning pad does not cover the at least one steam outlet.

3. The surface cleaning apparatus according to claim 1 , and further comprising a cleaning solution reservoir in fluid communication with the steam generator.

4. The surface cleaning apparatus according to claim 3 , and further comprising an auxiliary solution reservoir in fluid communication with the at least one steam outlet, downstream of the steam generator.

5. The surface cleaning apparatus according to claim 1 , wherein the steam distribution manifold comprises a hollow member with a plurality of apertures defining the at least one steam outlet.

6. The surface cleaning apparatus according to claim 5 , wherein the hollow member defines an elongate channel fluidly connecting the steam generator to the plurality of apertures.

7. The surface cleaning apparatus according to claim 1 , wherein the steam distribution manifold comprises a pair of arms pivotally mounted to the foot.

8. The surface cleaning apparatus according to claim 7 , wherein the arms comprise detents for retaining the steam distribution manifold in at least one of the first position or the second position.

9. The surface cleaning apparatus according to claim 7 , and further comprising a conduit in fluid communication between the steam generator and the at least one steam outlet, wherein the conduit extends through one of the pair of arms.

10. The surface cleaning apparatus according to claim 1 , and further comprising a conduit in fluid communication between the steam generator and the at least one steam outlet for conveying steam generated by the steam generator through the steam distribution manifold and onto the surface to be cleaned.

11. The surface cleaning apparatus according to claim 1 , wherein the cleaning pad comprises a superabsorbent polymer.

12. The surface cleaning apparatus according to claim 11 , wherein the superabsorbent polymer comprises at least one of hydrophilic cellulosic fibers or hydrogel-forming particles.

13. The surface cleaning apparatus according to claim 11 , wherein the cleaning pad further comprises a top sheet of non-woven material and a bottom sheet of non-woven material, with the superabsorbent polymer between the top and bottom sheets.

14. The surface cleaning apparatus according to claim 13 , wherein the top and bottom sheets are bonded together around the superabsorbent polymer to form flaps at the ends of cleaning pad, wherein the flaps can be used to secure the cleaning pad to the foot.

15. The surface cleaning apparatus of claim 1 , wherein the steam distribution manifold is pivotally mounted to the foot for movement about the foot between the first and second positions.

16. The surface cleaning apparatus of claim 1 , wherein the cleaning pad is coupled with the frame, and wherein the cleaning pad is positioned to contact the surface to be cleaned when the steam distribution manifold is in the first and second positions.
