Abstract

A bare floor cleaner has a base and a handle pivotally connected to the base. The handle is movable between a dry mode position and a wet mode position. A fluid delivery system of the bare floor cleaner includes a source of cleaning fluid and a fluid distributor in fluid communication with the source of cleaning fluid for dispensing cleaning fluid onto a surface to be cleaned. A recovery system of the bare floor cleaner includes a disabling mechanism for disabling the recovery system when the fluid distributor is dispensing cleaning fluid onto the surface to be cleaned.

First claim

What is claimed is:

1. A wet/dry bare floor cleaner, comprising:
a base;
a handle pivotally connected to the base for movement between a dry mode position and a wet mode position;
a recovery system for collecting dirt when the handle is in the dry mode position and comprising a motor/fan assembly carried by one of the handle and the base; and
a fluid delivery system comprising a source of cleaning fluid and a fluid distributor in fluid communication with the source of cleaning fluid for dispensing cleaning fluid onto a surface to be cleaned;
wherein the recovery system includes a deactivator mechanism adapted to deactivate the motor/fan assembly when the fluid distributor is dispensing cleaning fluid onto the surface to be cleaned,
wherein the fluid delivery system includes a disabling mechanism adapted to disable the recovery system when the fluid distributor is dispensing cleaning fluid onto the surface to be cleaned.

2. The wet/dry bare floor cleaner from claim 1 , wherein the deactivator mechanism includes a switch that controls the supply of electrical energy to the motor/fan assembly.

3. The wet/dry bare floor cleaner from claim 2 , wherein the disabling mechanism includes a trigger operably coupled with the fluid delivery system, whereby cleaning fluid can be dispensed from the source of cleaning fluid by depression of the trigger, and wherein the trigger is further operably connected to the switch such that the motor/fan assembly is automatically deactivated when the trigger is pressed.

4. The wet/dry bare floor cleaner from claim 3 , wherein the handle comprises a hand grip, and the trigger is positioned on one side of the hand grip for convenient operation by a finger of a user in the wet mode position and for inconvenient operation by the finger of the user in the dry mode position.

5. The wet/dry bare floor cleaner from claim 4 , wherein the handle is at an acute angle with respect to the vertical in a first direction in the dry mode position and the handle is at an acute angle with respect to the vertical in a second direction in the wet mode position.

6. The wet/dry bare floor cleaner from claim 1 and further comprising a suction nozzle on the base.

7. The wet/dry bare floor cleaner from claim 6 , wherein the recovery system includes a diverter valve movable between an open position when the handle is in the dry mode position and a closed position when the handle is in a wet mode position, wherein the motor/fan assembly is blocked from fluid communication with the suction nozzle when the diverter valve is in the closed position.

8. The wet/dry bare floor cleaner from claim 6 , wherein the suction nozzle is positioned on one side of the base and the fluid distributor is positioned on another side of the base.

9. The wet/dry bare floor cleaner from claim 8 and further comprising a cleaning pad mounted to an underside of the base.

10. The wet/dry bare floor cleaner from claim 8 , wherein the fluid distributor includes a spray nozzle for projecting cleaning fluid onto the surface.

11. The wet/dry bare floor cleaner from claim 1 and further comprising a heating element to raise the temperature of the cleaning fluid to be dispensed to the surface to be cleaned.

12. A wet/dry bare floor cleaner, comprising:
a base;
a handle pivotally connected to the base for movement between a dry mode position and a wet mode position;
a recovery system for collecting dirt when the handle is in the dry mode position; and
a fluid delivery system comprising a source of cleaning fluid and a fluid distributor in fluid communication with the source of cleaning fluid for dispensing cleaning fluid onto a surface to be cleaned;
wherein the fluid delivery system includes a disabling mechanism adapted to disable the recovery system when the fluid distributor is dispensing cleaning fluid onto the surface to be cleaned.

13. The wet/dry bare floor cleaner from claim 12 , wherein the recovery system comprises a motor/fan assembly carried by one of the handle and the base, and a deactivator mechanism coupled to the motor/fan assembly to deactivate the motor/fan assembly when fluid is being dispensed.

14. The wet/dry bare floor cleaner from claim 13 , wherein the deactivator mechanism includes a trigger operably connected to a switch that controls the supply of electrical energy to the motor/fan assembly.

15. The wet/dry bare floor cleaner from claim 14 , wherein the handle comprises a hand grip, and the trigger is positioned on one side of the hand grip for convenient operation by a finger of a user in the wet mode position and for inconvenient operation by the finger of the user in the dry mode position.

16. The wet/dry bare floor cleaner from claim 12 , wherein the handle is at an acute angle with respect to the vertical in a first direction in the dry mode position and the handle in at an acute angle with respect to the vertical in a second direction in the wet mode position.

17. The wet/dry bare floor cleaner from claim 12 , wherein the recovery system includes a diverter valve movable between an open position when the handle is in the dry mode position and a closed position when the handle is in the wet mode position.

18. The wet/dry bare floor cleaner from claim 12 and further comprising a suction nozzle on the base.

19. The wet/dry bare floor cleaner from claim 18 , wherein the recovery system includes a motor/fan assembly carried by one of the one handle and the base, and a diverter valve movable between an open position when the handle is in the dry mode position and a closed position when the handle is in the wet mode position, wherein the motor/fan assembly is blocked from fluid communication with the suction nozzle when the diverter valve is in the closed position.

20. The wet/dry bare floor cleaner from claim 18 , wherein the suction nozzle is positioned on one side of the base and the fluid distributor is positioned on another side of the base.
