Abstract

An upright bare floor cleaner with a handle assembly pivotally mounted to a base assembly. The handle includes a water tank to store a quantity of water and a fluid distribution system that includes a heater and a spray nozzle. Steam is generated by the heater and is distributed to a removable cleaning cloth that applies the steam to the surface to be cleaned. The fluid distribution system further includes an auxiliary hand tool for steam cleaning above-floor surfaces.

Claims

1. A bare floor cleaner comprising:

a housing having a foot and an upright handle assembly pivotally mounted to the foot; and

a fluid distribution system comprising;

a steam module removably mounted to the upright handle assembly, and comprising a steam generator having an inlet and an outlet;

a fluid distributor in the foot for distributing steam to a floor surface;

an auxiliary hose coupled to the steam module such that the auxiliary hose is removable with the steam module from the upright handle assembly; and

a fluid control system associated with the fluid distribution system for selectively distributing steam to the fluid distributor;

wherein the auxiliary hose is coupled to the exterior of the steam module such that a first end of the auxiliary hose is removable from the steam module for distributing steam to an above-the-floor surface.

2. The bare floor cleaner according to claim 1 wherein the fluid control system includes a diverter valve and a selector for selectively controlling the diverter valve for distributing steam either to the foot or the auxiliary hose.

3. The bare floor cleaner according to claim 1 wherein the auxiliary hose has a handheld nozzle and a fluid control valve, and the fluid control system comprises a receiver mounted on the housing for selectively receiving the handheld nozzle and to open the fluid control valve when the handheld nozzle is positioned in the receiver;

wherein steam is distributed to the floor via the fluid distributor when the handheld nozzle is received in the receiver and steam is distributed through the auxiliary hose when the handheld nozzle is removed from the receiver.

4. The bare floor cleaner according to claim 3 wherein the fluid control system comprises an electrical system for controlling the output of steam from the steam generator when the steam module is mounted to the upright handle and for controlling the delivery of steam from the steam generator to the auxiliary hose when the steam module is removed from the upright handle.

5. The bare floor cleaner according to claim 4 wherein the fluid distribution system comprises a water tank and a pump connected to the water tank and to the steam generator inlet for supplying water to the steam generator, and wherein the fluid control system comprises an electrical circuit for controlling power to the pump.

6. The bare floor cleaner according to claim 1 wherein the steam module includes a water tank adapted to hold a quantity of water that is fluidly connected to the steam generator inlet.

7. The bare floor cleaner according to claim 1 and further comprising a cleaning cloth which covers at least a portion of an under surface of the foot and is positioned for contacting the surface to be cleaned.

8. The bare floor cleaner according to claim 7 wherein the fluid distributor is positioned above the cleaning cloth for distributing steam to the cleaning cloth.

9. The bare floor cleaner according to claim 1 wherein the fluid control system further comprises a trigger on the handle operably connected to the fluid distribution system for selectively distributing steam onto the surface to be cleaned.

10. The bare floor cleaner according to claim 1 wherein the upright handle is pivotally mounted to the foot through a universal joint.

11. The bare floor cleaner according to claim 1 wherein the auxiliary hose comprises a flexible conduit, a handheld nozzle, and a manually operable fluid control valve.

12. The bare floor cleaner according to claim 1 wherein the steam module further comprises a support stand having support legs that can be deployed or retracted.

13. The bare floor cleaner according to claim 1 wherein the auxiliary hose is connected to the exterior of the steam module by an articulating joint.

14. The bare floor cleaner according to claim 13 wherein the auxiliary hose is mounted to the articulating joint for rotation about an axis.

15. The bare floor cleaner according to claim 1 wherein the fluid distribution system further comprises a moisture controller for selectively controlling the amount of moisture in the steam delivered to the fluid distributor and to the auxiliary hose.

16. The bare floor cleaner according to claim 1 wherein the auxiliary hose comprises a live hose with a second end in fluid communication with the outlet of the steam generator, and wherein the live hose is configured to be fluidly coupled to the fluid distributor in the foot via the first end when the steam module is mounted to the upright handle.
