Abstract

A floor cleaning machine including a base including a suction nozzle and a distribution nozzle, a handle pivotably coupled to the base about a pivot axis, a supply tank assembly coupled to the handle, and a suction motor assembly in fluid communication with the suction nozzle. The floor cleaning machine further includes a recovery tank coupled to the handle in fluid communication with the suction motor assembly to receive and store fluid and dirt drawn through the suction nozzle and an expandable hose fluidly communicating the recovery tank and the suction nozzle. The hose is in an expanded configuration when the handle is pivoted to a substantially upright position and the hose is in a retracted configuration when the handle is pivoted about the pivot axis to a reclined position and the hose at least partially wraps around the pivot axis in the expanded and the retracted configurations.

First claim

What is claimed is:

1. A floor cleaning machine for cleaning a surface, the floor cleaning machine comprising:
a base including a suction nozzle and a distribution nozzle;
a handle pivotably coupled to the base, the handle pivotable relative to the base about a pivot axis;
a supply tank assembly coupled to the handle in fluid communication with the distribution nozzle;
a suction motor assembly in fluid communication with the suction nozzle, the suction motor assembly operable to draw fluid and dirt from the surface through the suction nozzle;
a recovery tank coupled to the handle in fluid communication with the suction motor assembly to receive and store fluid and dirt drawn through the suction nozzle; and
an expandable hose fluidly communicating the recovery tank and the suction nozzle, wherein the hose is in an expanded configuration when the handle is pivoted about the pivot axis to a substantially upright position, wherein the hose is in a retracted configuration when the handle is pivoted about the pivot axis to a reclined position, and wherein the hose at least partially wraps around the pivot axis between the pivot axis and the surface being cleaned in the expanded and the retracted configurations.

2. The floor cleaning machine of claim 1 , wherein the handle includes a cylindrically shaped housing wherein the hose at least partially wraps around the cylindrically shaped housing when the hose is in the expanded configuration.

3. The floor cleaning machine of claim 2 , wherein the pivot axis extends through the cylindrically shaped housing.

4. The floor cleaning machine of claim 2 , wherein the pivot axis extends centrally through the cylindrically shaped housing.

5. The floor cleaning machine of claim 2 , wherein the cylindrically shaped housing includes a motor housing, the suction motor assembly positioned in the motor housing.

6. The floor cleaning machine of claim 5 , wherein the hose is slidably engageable with the motor housing when the handle is moved between the substantially upright position and the reclined position.

7. The floor cleaning machine of claim 5 , wherein the hose assumes a substantially arcuate shape when in the expanded configuration to follow the substantially cylindrical shape of the motor housing.

8. The floor cleaning machine of claim 5 , wherein the hose at least partially wraps around at least one of a bottom and a rear of the motor housing when in the expanded configuration.

9. The floor cleaning machine of claim 1 , wherein the hose wraps around the pivot axis to define a first arc length in the expanded configuration, wherein the hose wraps around the pivot axis to define a second arc length in the retracted configuration, and wherein the first arc length is greater than the second arc length.

10. The floor cleaning machine of claim 1 , wherein the handle further includes a motor housing, the suction motor assembly positioned in the motor housing, wherein the hose at least partially wraps around the motor housing portion when in the expanded configuration.

11. The floor cleaning machine of claim 1 , wherein the recovery tank is located below the supply tank assembly.

12. The floor cleaning machine of claim 1 , wherein the recovery tank is coupled between the supply tank assembly and the pivot axis.

13. A floor cleaning machine for cleaning a surface, the floor cleaning machine comprising:
a base including a suction nozzle and a distribution nozzle;
a handle pivotably coupled to the base, the handle pivotable relative to the base about a pivot axis, the handle including a housing having a cylindrical portion and the pivot axis extends through the housing;
a supply tank assembly coupled to the handle in fluid communication with the distribution nozzle;
a suction motor assembly in fluid communication with the suction nozzle, the suction motor assembly operable to draw fluid and dirt from the surface through the suction nozzle;
a recovery tank coupled to the handle in fluid communication with the suction motor assembly to receive and store fluid and dirt drawn through the suction nozzle; and
an expandable hose fluidly communicating the recovery tank and the suction nozzle, wherein the hose is in an expanded configuration when the handle is pivoted about the pivot axis to a substantially upright position, wherein the hose is in a retracted configuration when the handle is pivoted about the pivot axis to a reclined position, and wherein the hose at least partially wraps around the cylindrical portion of the housing in the expanded and the retracted configurations.

14. The floor cleaning machine of claim 13 , wherein the hose at least partially wraps around the pivot axis in the expanded and the retracted configurations.

15. The floor cleaning machine of claim 13 , wherein the pivot axis extends centrally through the cylindrical portion of the housing.

16. The floor cleaning machine of claim 13 , wherein the housing includes a motor housing, the suction motor assembly positioned in the motor housing.

17. The floor cleaning machine of claim 16 , wherein the hose is slidably engageable with the motor housing when the handle is moved between the substantially upright position and the reclined position.

18. The floor cleaning machine of claim 13 , wherein the hose assumes a substantially arcuate shape when in the expanded configuration to follow the substantially cylindrical shape of the cylindrical portion of the housing.

19. The floor cleaning machine of claim 13 , wherein the hose wraps around the cylindrical portion of the housing to define a first arc length in the expanded configuration, wherein the hose wraps around the cylindrical portion of the housing to define a second arc length in the retracted configuration, and wherein the first arc length is greater than the second arc length.

20. The floor cleaning machine of claim 1 , wherein the housing includes a motor housing, the suction motor assembly positioned in the motor housing, wherein the hose at least partially wraps around the motor housing when in the expanded configuration.
