Abstract

A floor cleaner including a vacuum source and a base movable over a surface to be cleaned. The base includes a front side, a back side opposite the front side, a lower end configured to be adjacent the surface to be cleaned, a suction inlet adjacent the front side and adjacent the lower end of the base and in fluid communication with the vacuum source, a brushroll rotatable about a brushroll axis, a first squeegee that extends from the lower end between the suction inlet and the back side of the base, the first squeegee configured to contact the surface to be cleaned. The base further includes a second squeegee that contacts the brushroll and the brushroll axis is between the lower end of the base and the second squeegee.

First claim

What is claimed is:

1. A floor cleaner comprising:
a supply tank configured to store a cleaning fluid;
a distribution nozzle in fluid communication with the supply tank, the distribution nozzle configured to dispense the cleaning fluid onto a surface to be cleaned;
a vacuum source; and
a base movable over the surface to be cleaned, the base including,
a front side,
a back side opposite the front side,
a lower end configured to be adjacent the surface to be cleaned,
a suction inlet adjacent the front side and adjacent the lower end of the base and in fluid communication with the vacuum source,
a brushroll rotatable about a brushroll axis,
a first squeegee that extends from the lower end between the suction inlet and the back side of the base, the first squeegee configured to contact the surface to be cleaned,
a second squeegee that contacts the brushroll, and
wherein the brushroll axis is between the lower end of the base and the second squeegee.

2. The floor cleaner of claim 1 , wherein the brushroll extends beyond the lower end of the base, wherein the suction inlet is between the first squeegee and a location wherein the brushroll extends beyond the lower end of the base.

3. The floor cleaner of claim 1 , wherein the first squeegee extends in a direction along the brushroll axis.

4. The floor cleaner of claim 1 , wherein the first squeegee extends along the suction inlet.

5. The floor cleaner of claim 1 , further comprising a brush that extends from the lower end of the base adjacent the first squeegee.

6. The floor cleaner of claim 5 , wherein the brush includes a row of bristles between the first squeegee and the back side of the base.

7. The floor cleaner of claim 5 , wherein the brush and the first squeegee are removable from the base as a unit.

8. The floor cleaner of claim 1 , wherein the brushroll axis is between the front side of the base and the second squeegee.

9. The floor cleaner of claim 1 , wherein the second squeegee extends along the brushroll axis.

10. The floor cleaner of claim 1 , wherein the base further includes a brushroll cover releasably attached to the base, the brushroll cover removable to access the brushroll.

11. The floor cleaner of claim 10 , wherein the second squeegee is attached to the brushroll cover and the second squeegee is removable from the base with the brushroll cover.

12. The floor cleaner of claim 10 , wherein the brushroll cover includes a front edge that is raised from the surface to be cleaned forming a front opening that exposes the brushroll.

13. The floor cleaner of claim 12 , wherein the brushroll is positioned that a portion of the brushroll extends forward of the front side.

14. The floor cleaner of claim 13 , wherein the distribution nozzle is configured to dispense the cleaning fluid forward of the front side.

15. The floor cleaner of claim 1 , further comprising a roller that extends from the lower end of the base, the roller configured to roll along the surface to be cleaned.

16. The floor cleaner of claim 15 , wherein the roller is adjacent a front side of the base.

17. The floor cleaner of claim 15 , wherein the roller is between the front side of the base and the brushroll axis.

18. The floor cleaner of claim 15 , wherein the roller is between the front side of the base and a location where the brushroll extends beyond the lower end of the base.
