Abstract

A floor cleaner including a vacuum source, a supply tank, and a recovery tank. The floor cleaner is configured to remove debris and fluid from a surface to be cleaned. The recovery tank includes a removably coupleable strainer configured to filter hair and large debris from a dirty fluid during emptying of the recovery tank.

Claims (36)

1. A floor cleaner comprising:

a vacuum source;

a supply tank configured to store a cleaning fluid;

a distribution nozzle in fluid communication with the supply tank, the distribution nozzle configured to dispense the cleaning fluid onto a surface to be cleaned;

a suction inlet in fluid communication with the vacuum source; and

a recovery tank in fluid communication with the vacuum source and the suction inlet, the recovery tank configured to store the cleaning fluid drawn through the suction inlet from the surface by the vacuum source,

the recovery tank including,

a tank body having a lower end wall, an open upper end, and a sidewall that extends upwardly from the lower end wall to the open upper end; and

a cover assembly removably coupled to the open upper end, configured to close the open upper end in a coupled position and uncover the open upper end in an uncoupled position;

a strainer positionable in the tank body in a seated position with the cover assembly in the uncoupled position, the strainer including a perforated body;

wherein the cover assembly is coupleable to the open upper end when the strainer is removed from the tank body and the cover assembly is not coupleable to the open upper end when the strainer is positioned inside the tank body, and

wherein the perforated body of the strainer is disposed adjacent the sidewall when the strainer is in the seated position.

2. The floor cleaner of claim 1 , wherein the recover tank includes an inlet duct in communication with the suction inlet, the inlet duct extending upwardly from the lower end wall, wherein the strainer is coupled to an upper portion of the inlet duct in the seated position.

3. The floor cleaner of claim 2 , wherein the strainer is coupled to an outer portion of the inlet duct in friction engagement in the seated position.

4. The floor cleaner of claim 2 , wherein the inlet duct is covered by the strainer when the strainer is in the seated position.

5. The floor cleaner of claim 1 , wherein the strainer is releasably coupled to the recovery tank when the strainer is in the seated position.

6. The floor cleaner of claim 1 , wherein the strainer interferes with the cover assembly when the strainer is in the seated position.

7. The floor cleaner of claim 1 , wherein at least one of the strainer and the floor cleaner has a connecting member configured to connect the strainer to the floor cleaner for storage when the strainer is removed from the tank body.

8. The floor cleaner of claim 1 , wherein the cover assembly includes a shutoff float.

9. A floor cleaner comprising:

a vacuum source;

a supply tank configured to store a cleaning fluid;

a distribution nozzle in fluid communication with the supply tank, the distribution nozzle configured to dispense the cleaning fluid onto a surface to be cleaned;

a suction inlet in fluid communication with the vacuum source;

a recovery tank in fluid communication with the vacuum source and the suction inlet, the recovery tank configured to store the cleaning fluid drawn through the suction inlet from the surface by the vacuum source, the recovery tank including,

a tank body having a lower end wall, an open upper end, a sidewall that extends upwardly from the lower end wall to the open upper end, and an inlet duct that extends upwardly from the lower end wall; and

a cover assembly removably coupled to the open upper end, configured to close the open upper end in a coupled position;

a strainer removably coupled to the inlet duct, the strainer including a perforated body,

wherein the cover assembly can be coupled to the open upper end when the strainer is removed from the tank body, and the cover assembly cannot be coupled to the open upper end when the strainer is coupled to the tank body, and

wherein the strainer is coupleable inside the tank body with the perforated body disposed adjacent the sidewall when the cover assembly is removed from the tank body.

10. The floor cleaner of claim 9 , wherein the strainer is coupled to an outside portion of the inlet duct in friction engagement.

11. The floor cleaner of claim 9 , wherein the strainer is coupled to an uppermost portion of the inlet duct.

12. The floor cleaner of claim 9 , wherein the inlet duct is covered by the strainer when the strainer is coupled to the inlet duct.

13. The floor cleaner of claim 9 , wherein at least one of the strainer and the floor cleaner has a connecting member configured to connect the strainer to the floor cleaner for storage of the strainer when the strainer is removed from the inside of the tank body.

14. The floor cleaner of claim 9 , wherein the strainer interferes with the cover assembly when the strainer is coupled to the inlet duct.

15. The floor cleaner of claim 9 , wherein the cover assembly includes a shutoff float.
