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 body including a suction nozzle thereon;
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 fluidly communicating the recovery tank and the suction nozzle, wherein the hose is in one of a retracted configuration and an expanded configuration when the handle is pivoted to a substantially upright position, wherein the hose is in the other of the retracted configuration and the expanded configuration when the handle is pivoted to the reclined position, and wherein the hose at least partially wraps around the motor housing portion when in the expanded configuration,
wherein the hose is in the retracted configuration when the handle is pivoted to the substantially upright position, and wherein the hose is in the expanded configuration when the handle is pivoted to the reclined position, and
wherein the hose is engageable with the motor housing portion when the hose is in the expanded configuration.

2. A floor cleaning machine for cleaning a surface, the floor cleaning machine comprising:
a body including a suction nozzle thereon;
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 fluidly communicating the recovery tank and the suction nozzle, wherein the hose is in one of a retracted configuration and an expanded configuration when the handle is pivoted to a substantially upright position, wherein the hose is in the other of the retracted configuration and the expanded configuration when the handle is pivoted to the reclined position, and wherein the hose at least partially wraps around the motor housing portion when in the expanded configuration,
wherein the hose is in the retracted configuration when the handle is pivoted to the substantially upright position, and wherein the hose is in the expanded configuration when the handle is pivoted to the reclined position, and
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.

3. A floor cleaning machine for cleaning a surface, the floor cleaning machine comprising:
a body including a suction nozzle thereon;
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 fluidly communicating the recovery tank and the suction nozzle, wherein the hose is in one of a retracted configuration and an expanded configuration when the handle is pivoted to a substantially upright position, wherein the hose is in the other of the retracted configuration and the expanded configuration when the handle is pivoted to the reclined position, and wherein the hose at least partially wraps around the motor housing portion when in the expanded configuration,
wherein the hose is in the retracted configuration when the handle is pivoted to the substantially upright position, and wherein the hose is in the expanded configuration when the handle is pivoted to the reclined position, and
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.

4. The floor cleaning machine of claim 3 , wherein the hose wraps around an arc length of the motor housing portion of at least about 30 degrees when in the expanded configuration.

5. The floor cleaning machine of claim 3 , wherein the hose wraps around an arc length of the motor housing portion of about 10 degrees or less when in the retracted configuration.

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

7. The floor cleaning machine of claim 1 , wherein the suction nozzle includes an inlet adjacent the surface and an outlet, and wherein the hose includes an inlet attached to the outlet of the suction nozzle.

8. A floor cleaning machine for cleaning a surface, the floor cleaning machine comprising:
a body including a suction nozzle thereon;
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 fluidly communicating the recovery tank and the suction nozzle, wherein the hose is in one of a retracted configuration and an expanded configuration when the handle is pivoted to a substantially upright position, wherein the hose is in the other of the retracted configuration and the expanded configuration when the handle is pivoted to the reclined position, and wherein the hose at least partially wraps around the motor housing portion when in the expanded configuration,
wherein the handle includes a recovery tank support portion upon which the recovery tank is positioned, and wherein the hose includes an outlet attached to the recovery tank support portion and in fluid communication with the recovery tank.

9. The floor cleaning machine of claim 1 , wherein the hose is configured as a flexible and expandable bellows-type plastic hose.

10. A floor cleaning machine for cleaning a surface, the floor cleaning machine comprising:
a body including a suction nozzle thereon
a handle pivotably coupled to the body, 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:
