Abstract

A floor cleaning machine including a handle that pivots relative to a base about a pivot axis. A recovery tank is coupled to the handle in fluid communication with a suction motor assembly to receive and store fluid and dirt drawn through a suction nozzle. The floor cleaning machine further includes an expandable hose fluidly communicating the recovery tank and the suction nozzle. The hose is in an expanded configuration when the handle is pivoted about the pivot axis to a reclined position. The hose is in a retracted configuration when the handle is pivoted about the pivot axis to a substantially upright position. The hose at least partially wraps around the pivot axis with the pivot axis being between a portion of the hose wrapped around the pivot axis and the surface being cleaned in the expanded and the retracted configurations.

First claim

What is claimed is:

1. A floor cleaner for cleaning a surface, the floor cleaner comprising:
a body including a suction nozzle supported by a front portion of the body, the suction nozzle including a downward-facing inlet adjacent the surface;
the body including wheels to facilitate movement of the body along the surface;
the body including one or more brushes adjacent the suction nozzle;
the body including a distribution nozzle configured to direct cleaning solution onto the surface;

a handle pivotably coupled to the body, the handle pivotable relative to the body about a pivot axis between an upright storage position and a reclined operating position;
the handle including a motor housing portion;
the motor housing portion including a substantially cylindrical portion with a central axis extending in a lateral direction relative to the body;
the central axis of the motor housing portion coinciding with the pivot axis between the handle and the body;
the motor housing portion disposed between the wheels and pivotable with the handle relative to the body about the pivot axis;

the handle including a recovery tank support portion pivotable with the handle relative to the body about the pivot axis;
wherein the motor housing portion is between the recovery tank support portion and the suction nozzle in the reclined operating position;

a supply tank assembly releasably coupled to the handle in fluid communication with the distribution nozzle;
a suction motor assembly positioned in the motor housing portion, the suction motor assembly in fluid communication with the suction nozzle and the suction motor assembly operable to draw fluid and dirt from the surface through the suction nozzle;
a recovery tank coupled to the recovery tank support portion in fluid communication with the suction motor assembly to receive and store fluid and dirt drawn through the suction nozzle;
wherein the recovery tank is coupled to the handle below the supply tank;

an expandable hose fluidly communicating the recovery tank and the suction nozzle;
the expandable hose including an inlet connected to an outlet of the suction nozzle;
the expandable hose including an outlet connected to an opening in the recovery tank support portion of the handle in fluid communication with the recovery tank;
the expandable hose having a middle portion expandable and stretchable around the motor housing portion when the handle is pivoted between the upright storage position and the reclined operating position;
wherein the expandable hose is in one of a retracted configuration and an expanded configuration when the handle is pivoted to a substantially upright position, wherein the expandable hose is in the other of the retracted configuration and the expanded configuration when the handle is pivoted to the reclined position.

2. The floor cleaner of claim 1 , wherein the expandable hose is in the expanded configuration when the handle is pivoted to the upright position, and wherein the expandable hose is in the retracted configuration when the handle is pivoted to the reclined position.

3. The floor cleaner of claim 1 , wherein the expandable hose is in the retracted configuration when the handle is pivoted to the upright position, and wherein the expandable hose is in the expanded configuration when the handle is pivoted to the reclined position.

4. The floor cleaner of claim 1 , wherein the expandable hose is slidably engaged with the motor housing portion when the handle is moved between the upright storage position and the reclined operating position.

5. The floor cleaner of claim 1 , wherein the expandable hose wraps around an arc length of the motor housing portion of at least about 30 degrees when in the expanded configuration.

6. The floor cleaner of claim 1 , wherein the expandable hose wraps around an arc length of the motor housing portion of at least about 90 degrees when in the expanded configuration.

7. The floor cleaner of claim 1 , wherein the expandable hose is a flexible and expandable bellows-type plastic hose.

8. A floor cleaner for cleaning a surface, the floor cleaner comprising:
a body including a suction nozzle supported by a front portion of the body, the suction nozzle including a downward-facing inlet adjacent the surface;
the body including wheels to facilitate movement of the body along the surface;
the body including one or more brushes adjacent the suction nozzle;
the body including a distribution nozzle configured to direct cleaning solution onto the surface;

a handle pivotably coupled to the body, the handle pivotable relative to the body about a pivot axis between an upright storage position and a reclined operating position;
the handle including a motor housing portion;
the motor housing portion including a substantially cylindrical portion with a central axis extending in a lateral direction relative to the body;
the central axis of the motor housing portion coinciding with the pivot axis between the handle and the body;
the motor housing portion disposed between the wheels and pivotable with the handle relative to the body about the pivot axis;

the handle including a recovery tank support portion pivotable with the handle relative to the body about the pivot axis;
wherein the motor housing portion is between the recovery tank support portion and the suction nozzle in the reclined operating position;

a supply tank assembly releasably coupled to the handle in fluid communication with the distribution nozzle;
a suction motor assembly positioned in the motor housing portion, the suction motor assembly in fluid communication with the suction nozzle and the suction motor assembly operable to draw fluid and dirt from the surface through the suction nozzle;
a recovery tank coupled to the recovery tank support portion in fluid communication with the suction motor assembly to receive and store fluid and dirt drawn through the suction nozzle;
an expandable hose fluidly communicating the recovery tank and the suction nozzle;
the expandable hose including an inlet connected to an outlet of the suction nozzle;
the expandable hose including an outlet connected to an opening in the recovery tank support portion of the handle in fluid communication with the recovery tank;
the expandable hose having a middle portion expandable and stretchable around the motor housing portion when the handle is pivoted between the upright storage position and the reclined operating position;
wherein the expandable hose is in one of a retracted configuration and an expanded configuration when the handle is pivoted to a substantially upright position, wherein the expandable hose is in the other of the retracted configuration and the expanded configuration when the handle is pivoted to the reclined position.

9. The floor cleaner of claim 8 , wherein the expandable hose is in the expanded configuration when the handle is pivoted to the upright position, and wherein the expandable hose is in the retracted configuration when the handle is pivoted to the reclined position.

10. The floor cleaner of claim 8 , wherein the expandable hose is in the retracted configuration when the handle is pivoted to the upright position, and wherein the expandable hose is in the expanded configuration when the handle is pivoted to the reclined position.

11. The floor cleaner of claim 8 , wherein the expandable hose wraps around an arc length of the motor housing portion of at least about 30 degrees when in the expanded configuration.

12. The floor cleaner of claim 8 , wherein the expandable hose wraps around an arc length of the motor housing portion of at least about 90 degrees when in the expanded
