Abstract

A floor cleaning machine for cleaning a surface includes a body having a suction nozzle thereon, a handle pivotably coupled to the body and having a motor housing portion, and a suction motor assembly operable to draw fluid and dirt from the surface through the suction nozzle. The floor cleaning machine also 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 one of a retracted configuration and an expanded configuration when the handle is pivoted to a substantially upright position, and the other when pivoted to a reclined position. The hose at least partially wraps around the motor housing portion when in the expanded configuration.

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 including a motor housing portion; 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 and positioned in the motor housing portion, 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 to a substantially upright position, wherein the hose is in a retracted configuration when the handle is pivoted to a reclined position, and wherein the hose at least partially wraps around the motor housing portion when in the expanded configuration.

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

3 . The floor cleaning machine of claim 1 , wherein the hose is engageable with the motor housing portion when the hose is in the expanded configuration.

4 . The floor cleaning machine of claim 1 , wherein the hose is slidably engageable with the motor housing portion when the handle is moved between the substantially upright position and the reclined position.

5 . The floor cleaning machine of claim 1 , wherein the motor housing portion includes a substantially cylindrical shape, and wherein the hose assumes a substantially arcuate shape when in the expanded configuration to follow the substantially cylindrical shape of the motor housing portion.

6 . The floor cleaning machine of claim 1 , wherein the hose at least partially wraps around at least one of a bottom and a rear of the motor housing portion when in the expanded configuration.

7 . The floor cleaning machine of claim 1 , wherein the motor housing portion includes a substantially cylindrical shape defining a central axis, and wherein the central axis extends in a same direction as a pivot axis between the handle and the base.

8 . A floor cleaning machine for cleaning a surface, the floor cleaning machine comprising:
a base including a suction nozzle; a handle pivotably coupled to the base about an axis, the handle including a motor housing portion; a refillable supply tank assembly coupled to the handle; a suction motor assembly in fluid communication with the suction nozzle and positioned in the motor housing portion, the suction motor assembly operable to draw fluid and dirt from the surface through the suction nozzle; a recovery tank coupled to the handle below the supply tank assembly, the recovery tank 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 to a substantially upright position, wherein the hose is in a retracted configuration when the handle is pivoted to a reclined position, and wherein the hose at least partially wraps around the motor housing portion when in the expanded configuration.

9 . The floor cleaning machine of claim 8 , wherein the recovery tank is coupled between the supply tank assembly and the motor housing portion.

10 . The floor cleaning machine of claim 8 , wherein the hose is engageable with the motor housing portion when the hose is in the expanded configuration.

11 . The floor cleaning machine of claim 8 , wherein the hose is slidably engageable with the motor housing portion when the handle is moved between the substantially upright position and the reclined position.

12 . The floor cleaning machine of claim 8 , wherein the motor housing portion includes a substantially cylindrical shape, and wherein the hose assumes a substantially arcuate shape when in the expanded configuration to follow the substantially cylindrical shape of the motor housing portion.

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

14 . The floor cleaning machine of claim 8 , wherein the motor housing portion includes a substantially cylindrical shape defining a central axis, and wherein the central axis extends in a same direction as a pivot axis between the handle and the base.

15 . A floor cleaning machine for cleaning a surface, the floor cleaning machine comprising:
a body including a suction nozzle; a handle pivotably coupled to the body, the handle including a motor housing portion; a supply tank assembly coupled to the handle; a suction motor assembly in fluid communication with the suction nozzle and positioned in the motor housing portion, 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 non-removably coupled between the body and the handle to provide fluid communication between the recovery tank and the suction nozzle, wherein the hose is in an expanded configuration when the handle is pivoted to a substantially upright position, wherein the hose is in a retracted configuration when the handle is pivoted to a reclined position, and wherein the hose at least partially wraps around the motor housing portion when in the expanded configuration.

16 . The floor cleaning machine of claim 15 , wherein a portion of the handle includes an opening that receives an outlet of the expandable hose, and wherein the expandable hose is affixed to the portion of the handle.

17 . The floor cleaning machine of claim 16 , wherein an inlet of the expandable hose is affixed to an outlet of the suction nozzle.

18 . The floor cleaning machine of claim 15 , wherein the hose is slidably engageable with the motor housing portion when the handle is moved between the substantially upright position and the reclined position.

19 . The floor cleaning machine of claim 15 , wherein the motor housing portion includes a substantially cylindrical shape, and wherein the hose assumes a substantially arcuate shape when in the expanded configuration to follow the substantially cylindrical shape of the motor housing portion.

20 . The floor cleaning machine of claim 15 , wherein the hose at least partially wraps around at least one of a bottom and a rear of the motor housing portion when in the expanded configuration.
