Abstract

An extraction cleaner includes a portable extractor and a base adapted to be moved to perform a cleaning operation on a floor surface when the portable extractor is operably mounted to the base. The portable extractor includes a recovery tank assembly and a supply tank assembly provided on the housing adjacent to the recovery tank assembly.

First claim

What is claimed is:

1. An extraction cleaner for a floor surface, the extraction cleaner comprising:
a base moveable across a floor surface, the base comprising a suction nozzle juxtaposed with the floor surface;
a handle pivotally mounted to a rearward portion of the base;
a portable extractor removably mounted to the base, wherein the portable extractor can be used as a standalone extractor when removed from the base, the portable extractor comprising:
a housing having a suction source and a suction inlet, wherein when the portable extractor is mounted to the base the suction inlet is in fluid communication with the suction nozzle;
a recovery tank assembly provided on the housing and interconnected to the suction inlet;
a supply tank assembly provided on the housing laterally adjacent to the recovery tank assembly along a first axis; and
a carry handle provided on the housing between the recovery tank assembly and the supply tank assembly and defining a handle axis, wherein the handle axis is transverse to the first axis.

2. The extraction cleaner of claim 1 , wherein the base comprises a base platform that supports the portable extractor at a forward portion thereof relative to the handle.

3. The extraction cleaner of claim 1 , wherein the housing comprises a lower body in which the recovery tank assembly and the supply tank assembly are removably received.

4. The extraction cleaner of claim 3 , wherein the lower body encircles the recovery tank assembly and the supply tank assembly.

5. The extraction cleaner of claim 1 , wherein the carry handle comprises a handle grip extending above the recovery tank assembly and the supply tank assembly.

6. The extraction cleaner of claim 1 , wherein the recovery tank assembly and the supply tank assembly are removable from the housing, and wherein the recovery tank assembly comprises a second carry handle and the supply tank assembly comprises a third carry handle.

7. The extraction cleaner of claim 1 , wherein the supply tank assembly is provided on the housing rearward of the recovery tank assembly.

8. The extraction cleaner of claim 1 , wherein the portable extractor further comprises an accessory hose for manually suctioning fluid from a surface to be cleaned, wherein the suction inlet is an inlet of the accessory hose.

9. The extraction cleaner of claim 1 wherein:
the portable extractor further comprises a first recovery connection fluidly interconnected with the suction source; and
the base further comprises a second recovery connection fluidly interconnected with the suction nozzle and adapted to be connected with the first recovery connection when the portable extractor is operably mounted to the base, such that the suction source is fluidly interconnected to the suction nozzle by an interconnection of the first and second recovery connections.

10. The extraction cleaner of claim 9 wherein:
the portable extractor further comprises a first fluid delivery connection fluidly interconnected with the supply tank assembly; and
the base further comprises a second fluid delivery connection adapted to be connected with the first fluid delivery connection when the portable extractor is operably mounted to the base, such that cleaning fluid can be dispensed to the floor surface by the interconnection of the first and second fluid delivery connections.

11. The extraction cleaner of claim 1 wherein:
the portable extractor further comprises a first exhaust connection fluidly interconnected with an outlet of the suction source; and
the base further comprises an exhaust vent and a second exhaust connection fluidly interconnected with the exhaust vent and adapted to be connected with the first exhaust connection when the portable extractor is operably mounted to the base, such that the outlet of the suction source is fluidly interconnected to the exhaust vent by an interconnection of the first and second exhaust connections.

12. The extraction cleaner of claim 1 and further comprising a latch provided on one of the portable extractor and the base and a cooperating member on the other of the portable extractor and the base for retaining the portable extractor to the base, wherein the latch is movable with respect to the cooperating member between a first position wherein the latch retains the portable extractor to the base, and a second position wherein the portable extractor can be removed from the base.

13. An extraction cleaner for a floor surface, the extraction cleaner comprising:
a base moveable across the floor surface, the base comprising a suction nozzle juxtaposed with the floor surface;
a handle pivotally mounted to a rearward portion of the base;
a portable extractor removably mounted to the base, wherein the portable extractor can be used as a standalone extractor when removed from the base, the portable extractor comprising:
a housing having a suction source and a suction inlet, wherein when the portable extractor is mounted to the base the suction inlet is in fluid communication with the suction nozzle;
a recovery tank assembly provided on the housing and interconnected to the suction inlet;
a supply tank assembly provided on the housing laterally adjacent to the recovery tank assembly;
a wall provided on the housing and extending between the recovery tank assembly and the supply tank assembly to separate the recovery tank assembly from the supply tank assembly; and
a carry handle provided on the wall between the recovery tank assembly and the supply tank assembly.

14. The extraction cleaner of claim 13 , wherein the base comprises a base platform that supports the portable extractor at a forward portion thereof relative to the handle.

15. The extraction cleaner of claim 13 , wherein the housing comprises a lower body in which the recovery tank assembly and supply tank assembly are removably received.

16. The extraction cleaner of claim 15 , wherein the lower body encircles the recovery tank assembly and the supply tank assembly.

17. The extraction cleaner of claim 13 , wherein the carry handle comprises a handle grip extending above the recovery tank assembly and the supply tank assembly.

18. The extraction cleaner of claim 13 , wherein the recovery tank assembly and the supply tank assembly are removable from the housing, and wherein the recovery tank assembly comprises a second carry handle and the supply tank assembly comprises a third carry handle.

19. An extraction cleaner for a floor surface, the extraction cleaner comprising:
a base moveable across a floor, the base comprising a suction nozzle juxtaposed with the floor surface;
a handle pivotally mounted to a rearward portion of the base;
a portable extractor removably mounted to the base, wherein the portable extractor can be used as a standalone extractor when removed from the base, the portable extractor comprising:
a housing having a suction source and a suction inlet, wherein when the portable extractor is mounted to the base the suction inlet is in fluid communication with the suction nozzle;
a recovery tank assembly provided on the housing and interconnected to the suction inlet; and
a supply tank assembly provided on the housing rearward of the recovery tank assembly;
wherein the base comprises a base platform that supports the portable extractor at a forward portion thereof relative to the handle such that the recovery tank assembly and the supply tank assembly are forward of the handle.

20. The extraction cleaner of claim 19 , wherein the portable extractor compri
