Abstract

A cleaning head housing for a floor cleaner that moves along a surface to be cleaned includes a brushroll chamber defining a top surface having a top opening and a bottom surface having a bottom opening positioned closer to the surface to be cleaned than the top opening. A suction nozzle has an upper nozzle wall, a lower nozzle wall, and a nozzle passageway formed between the upper and lower nozzle walls. The suction nozzle is releaseably connected to the brushroll chamber to selectively cover the top opening of the brushroll chamber. A brushroll is positioned within the brushroll chamber and engages the surface to be cleaned through the bottom opening of the brushroll chamber. The brushroll is accessible through the top opening for cleaning while the suction nozzle is disconnected from the brushroll chamber. The brushroll is removable from the brushroll chamber other than through the top opening.

First claim

What is claimed is:

1. A floor cleaner comprising:
a cleaning head housing movable along a surface to be cleaned, the cleaning head housing including
a brushroll chamber defining a top opening and a bottom opening,
a suction nozzle having an upper nozzle wall, a lower nozzle wall, and a nozzle passageway formed between the upper nozzle wall and the lower nozzle wall, the suction nozzle being releaseably connected to the brushroll chamber to selectively cover the top opening of the brushroll chamber,
a brushroll positioned within the brushroll chamber, the brushroll configured to engage the surface to be cleaned through the bottom opening of the brushroll chamber during operation, the brushroll being accessible through the top opening for cleaning while the suction nozzle is disconnected from the brushroll chamber, the brushroll being removable from the brushroll chamber other than through the top opening;

a body portion pivotally coupled to the cleaning head housing;
a suction source in fluid communication with the suction nozzle, the suction source operable to draw fluid into the suction nozzle; and
a recovery tank in fluid communication with the suction nozzle and the suction source, the recovery tank configured to store fluid drawn through the suction nozzle.

2. The floor cleaner of claim 1 , wherein the brushroll is removable from the brushroll chamber through the bottom opening.

3. The floor cleaner of claim 1 , wherein the brushroll chamber includes a side opening and the cleaning head housing includes a side cover selectively covering the side opening, and wherein the brushroll is removable from the brushroll chamber through the side opening while the side cover is disconnected from the brushroll chamber.

4. The floor cleaner of claim 1 , wherein the lower nozzle wall has a lower nozzle wall width, and the top opening has a top opening width, wherein the lower nozzle wall width is greater than the top opening width.

5. The floor cleaner of claim 1 , wherein the cleaning head housing includes a suction duct, wherein the suction nozzle connects to the suction duct when the suction nozzle is connected to the brushroll chamber and is disconnected and spaced from the suction duct when the suction nozzle is disconnected from the brushroll chamber, and the suction nozzle communicates with the recovery tank via the suction duct while the suction nozzle is connected to the brushroll chamber.

6. The floor cleaner of claim 5 , wherein the brushroll defines a brushroll axis, wherein the suction nozzle pivots forward about an axis parallel to the brushroll axis as the suction nozzle is being moved from being connected to the brushroll chamber to being disconnected from the brushroll chamber.

7. The floor cleaner of claim 1 , wherein the brushroll has a brushroll width and the top opening of the brushroll chamber has a top opening width, wherein the brushroll width is greater than the top opening width.

8. A cleaning head housing for a floor cleaner movable along a surface to be cleaned, the cleaning head housing comprising:
a brushroll chamber defining a top surface having a top opening and a bottom surface having a bottom opening positioned closer to the surface to be cleaned than the top opening during operation of the floor cleaner;
a suction nozzle having an upper nozzle wall, a lower nozzle wall, and a nozzle passageway formed between the upper nozzle wall and the lower nozzle wall, the suction nozzle being releaseably connected to the brushroll chamber to selectively cover the top opening of the brushroll chamber; and
a brushroll positioned within the brushroll chamber, the brushroll configured to engage the surface to be cleaned through the bottom opening of the brushroll chamber during operation,
wherein the brushroll is accessible through the top opening for cleaning while the suction nozzle is disconnected from the brushroll chamber, and
wherein the brushroll is removable from the brushroll chamber other than through the top opening.

9. The cleaning head housing of claim 8 , wherein the brushroll is removable from the brushroll chamber through the bottom opening.

10. The cleaning head housing of claim 8 , wherein the brushroll chamber includes a side opening and the cleaning head housing includes a side cover selectively covering the side opening, and wherein the brushroll is removable from the brushroll chamber through the side opening while the side cover is disconnected from the brushroll chamber.

11. The cleaning head housing of claim 8 , wherein the lower nozzle wall has a lower nozzle wall width, and the top opening has a top opening width, wherein the lower nozzle wall width is greater than the top opening width.

12. The cleaning head housing of claim 8 , wherein the cleaning head housing includes a suction duct, wherein the suction nozzle connects to the suction duct when the suction nozzle is connected to the brushroll chamber and is disconnected and spaced from the suction duct when the suction nozzle is disconnected from the brushroll chamber, and the suction nozzle communicates with the recovery tank via the suction duct while the suction nozzle is connected to the brushroll chamber.

13. The cleaning head housing of claim 12 , wherein the brushroll defines a brushroll axis, wherein the suction nozzle pivots forward about an axis parallel to the brushroll axis as the suction nozzle is being moved from being connected to the brushroll chamber to being disconnected from the brushroll chamber.

14. The cleaning head housing of claim 8 , wherein the brushroll has a brushroll width and the top opening of the brushroll chamber has a top opening width, wherein the brushroll width is greater than the top opening width.

15. A floor cleaner comprising:
a cleaning head housing movable along a surface to be cleaned, the cleaning head housing including
a brushroll chamber defining a top opening, a bottom opening, and, optionally a side opening,
a dispensing nozzle configured to dispense fluid onto the surface to be cleaned;
a suction nozzle having an upper nozzle wall, a lower nozzle wall, and a nozzle passageway formed between the upper nozzle wall and the lower nozzle wall, the suction nozzle being releaseably connected to the brushroll chamber to selectively close the top opening of the brushroll chamber, and
a brushroll positioned within the brushroll chamber, the brushroll configured to engage the surface to be cleaned through the bottom opening of the brushroll chamber, the brushroll being accessible through the top opening for cleaning while the suction nozzle is disconnected from the brushroll chamber, the brushroll being removable from the brushroll chamber other than through the top opening;

a body portion pivotally coupled to the brushroll chamber;
a supply tank configured to supply fluid to the dispensing nozzle;
a suction source connected to the body portion, the suction source in fluid communication with the suction nozzle, the suction source operable to draw fluid into the suction nozzle from the surface to be cleaned; and
a recovery tank in fluid communication with the suction nozzle and the suction source, the recovery tank configured to store fluid drawn through the suction nozzle.

16. The floor cleaner of claim 15 , wherein the brushroll is removable from the brushroll chamber through the bottom opening.

17. The floor cleaner of claim 16 , wherein the cleaning head housing includes a side cover selectively covering the side opening, and wherein the brushroll is removable from the brushroll chamber through the side opening while the side cove
