Abstract

A floor cleaner including a base movable over a surface to be cleaned, the base including a front side, a back side opposite the front side, and a brushroll chamber. A supply tank is configured to store a cleaning fluid and a distribution nozzle is in fluid communication with the supply tank, the distribution nozzle operable to dispense the cleaning fluid onto the surface to be cleaned. A brushroll cover is removable from the base to access the brushroll chamber. A brushroll is within the brushroll chamber. The distribution nozzle is disposed adjacent the front side of the base and carried on an upper exterior portion of the base and configured to spray forwardly of the base in a direction from the back side toward the front side.

First claim

What is claimed is:

1. A floor cleaner comprising:
a vacuum source; and
a base movable over a surface to be cleaned, the base including,
a suction inlet in fluid communication with the vacuum source,
a brushroll chamber including a rear wall,
a brushroll in the brushroll chamber, the brushroll rotatable about a brushroll axis;
a brushroll cover releaseably attached to the base, the brushroll cover removable to access the brushroll chamber and the brushroll;

a supply tank configured to store a cleaning fluid,
wherein the base includes a distribution nozzle in fluid communication with the supply tank, and
wherein the distribution nozzle is coupled to the brushroll cover and removable with the brushroll cover from the base, and
further comprising a fluid coupling disposed between the base and the distribution nozzle, the fluid coupling configured to provide fluid communication between the supply tank and the distribution nozzle,
wherein the brushroll chamber includes a forward wall and the rear wall, and wherein the brushroll chamber rear wall is attached to and removable with the brushroll cover,
wherein the rear wall includes a brushroll chamber outlet in communication with the suction inlet and the vacuum source.

2. The floor cleaner of claim 1 , wherein the distribution nozzle is configured to dispense the cleaning fluid onto the surface.

3. A floor cleaner comprising:
a vacuum source; and
a base movable over a surface to be cleaned, the base including,
a suction inlet in fluid communication with the vacuum source,
a brushroll chamber including a rear wall,
a brushroll in the brushroll chamber, the brushroll rotatable about a brushroll axis;
a brushroll cover releaseably attached to the base, the brushroll cover removable to access the brushroll chamber and the brushroll;

a supply tank configured to store a cleaning fluid,
wherein the base includes a distribution nozzle in fluid communication with the supply tank, and
wherein the distribution nozzle is coupled to the brushroll cover and removable with the brushroll cover from the base, and
further comprising a fluid coupling disposed between the base and the distribution nozzle, the fluid coupling configured to provide fluid communication between the supply tank and the distribution nozzle,
wherein the base further includes
a first actuator movable in a first direction from a latched position and to an unlatched position;
a second actuator movable in a second direction, opposite the first direction, from a latched position and an unlatched position,
wherein the brushroll cover is secured to the base when the first and second actuators are in the latched positions and the brushroll cover is removable from the base when the first and second actuators are in the unlatched positions.

4. The floor cleaner of claim 3 , wherein the base includes a first latch and a second latch, wherein movement of the first actuator from the latched position to the unlatched position moves the first latch from an engaged position with the base to a disengaged position with the base, and wherein movement of the second actuator from the latched position to the unlatched position moves the second latch from an engaged position with the base to a disengaged position with the base.

5. The floor cleaner of claim 3 , wherein the first actuator and the second actuator are removable from the base with the brushroll cover.

6. The floor cleaner of claim 3 , wherein the first actuator and the second actuator are pressed toward the latched positions by a spring.

7. The floor cleaner of claim 3 , wherein the first direction and the second direction are directly opposed.

8. The floor cleaner of claim 3 , wherein the first actuator and the second actuator are configured to be operated by a single hand of a user.

9. The floor cleaner of claim 8 , wherein an upper portion of the first actuator and an upper portion of the second actuator form a grip for lifting the cover.

10. The floor cleaner of claim 3 , wherein the distribution nozzle is configured to dispense the cleaning fluid onto the surface.
