Abstract

A surface cleaning apparatus, and in particular a steam mop, comprises a steam generator and a steam outlet fluidly connected to the steam generator to deliver steam to a floor surface. Steam from the steam generator can be applied to a cleaning composition applied to a stain on the floor surface. The cleaning composition can be applied directly to the floor surface, or indirectly via a cleaning pad.

First claim

What is claimed is:

1. A surface cleaning apparatus, comprising:
a first reservoir configured to hold a supply of a solution;
a second reservoir wherein the second reservoir is devoid of a filter;
a steam generator in fluid communication with the first reservoir for heating the solution to at least 212 degrees Fahrenheit (100 degrees Celsius) to generate steam from the solution;
at least one steam outlet fluidly connected to the steam generator to deliver steam onto a stain on a surface to be cleaned;
a cleaning pad positioned to contact the stain on the surface to be cleaned; and
a cleaning composition in the second reservoir comprising a peroxygen and a surfactant;
an auxiliary distributor, separate from the steam outlet, the auxiliary distributor fluidly coupled with the second reservoir and wherein the steam generator, via the at least one steam outlet, is configured to apply steam to the cleaning composition at a time of delivery of the cleaning composition to the stain or subsequent to the delivery of the cleaning composition to the stain via the auxiliary distributor.

2. The surface cleaning apparatus of claim 1 , further comprising a foot movable along the surface to be cleaned and an upright housing coupled to the foot, wherein the cleaning pad is mounted on a lower surface of the foot.

3. The surface cleaning apparatus of claim 2 wherein the second reservoir is provided on the upright housing.

4. The surface cleaning apparatus of claim 3 wherein the auxiliary distributor further includes a spray tip fluidly coupled with the second reservoir to deliver the cleaning composition onto the stain on the surface to be cleaned.

5. The surface cleaning apparatus of claim 1 , further comprising a pad frame movable along the surface to be cleaned and a handle operably coupled to the pad frame, wherein the cleaning pad is mounted on the pad frame.

6. The surface cleaning apparatus of claim 5 , further comprising a cover mounted to the pad frame and defining a cavity which receives the steam generator.

7. The surface cleaning apparatus of claim 6 wherein the at least one steam outlet delivers steam onto the stain through at least a portion of the cleaning pad.

8. The surface cleaning apparatus of claim 1 wherein the cleaning pad is composed of 100% meltblown polypropylene.

9. The surface cleaning apparatus of claim 1 wherein the peroxygen is dilute hydrogen peroxide and the surfactant is sodium lauryl sulfate.

10. The surface cleaning apparatus of claim 1 wherein the cleaning composition further comprises a fragrance.

11. The surface cleaning apparatus of claim 1 wherein the auxiliary distributor further includes a spray tip fluidly coupled with the second reservoir to deliver the cleaning composition onto the stain on the surface to be cleaned.

12. A surface cleaning apparatus, comprising:
a steam supply assembly, comprising:
a first reservoir configured to hold a supply of a solution;
a steam generator in fluid communication with the first reservoir for heating the solution to at least 212 degrees Fahrenheit (100 degrees Celsius) to generate steam from the solution; and
at least one steam outlet fluidly connected to the steam generator to deliver steam onto a stain on a surface to be cleaned; and

a cleaning composition assembly that is separate from the steam supply assembly, the cleaning composition assembly comprising:
a second reservoir;
a cleaning composition in the second reservoir comprising a peroxygen and a surfactant;
a dedicated spray tip fluidly coupled with the second reservoir via a conduit, the dedicated spray tip configured to deliver the cleaning composition onto the stain on the surface to be cleaned;

wherein the steam generator is configured to apply steam to the cleaning composition at a time of delivery of the cleaning composition to the stain from the dedicated spray tip or subsequent to the delivery of the cleaning composition to the stain from the dedicated spray tip.

13. The surface cleaning apparatus of claim 12 , further comprising a foot movable along the surface to be cleaned and an upright housing coupled to the foot.

14. The surface cleaning apparatus of claim 13 wherein the second reservoir is provided on the upright housing.

15. The surface cleaning apparatus of claim 13 , further comprising a cleaning pad mounted on a lower surface of the foot.

16. The surface cleaning apparatus of claim 15 wherein the foot comprises a pad frame and wherein the cleaning pad is mounted on the pad frame.

17. The surface cleaning apparatus of claim 16 , further comprising a cover mounted to the pad frame and defining a cavity which receives the steam generator.

18. The surface cleaning apparatus of claim 15 wherein the at least one steam outlet delivers steam onto the stain through at least a portion of the cleaning pad.

19. The surface cleaning apparatus of claim 12 wherein the peroxygen is dilute hydrogen peroxide and the surfactant is sodium lauryl sulfate.

20. The surface cleaning apparatus of claim 19 wherein the cleaning composition further comprises a fragrance.
