Abstract

A portable extractor includes a supply tank, a recovery tank, a pump in fluid communication with the supply tank, a suction source in fluid communication with the recovery tank, a base configured to support the suction source and the pump, and a main housing mounted on the base and housing the suction source and the pump. The main housing is configured to removably support the recovery tank and the supply tank. The recovery tank is arranged at a front side of the portable extractor and the supply tank is arranged at a lateral side of the portable extractor between the front side and the rear side.

First claim

What is claimed is:

1. A portable extraction cleaner comprising:
a main housing including a housing body that defines a front portion, a rear portion, and an intermediate portion coupled between the front portion and the rear portion, the intermediate portion defines a supply tank cavity;
a recovery tank supported by the main housing, the recovery tank having portions at least partially defining a front side and a top side of the portable extraction cleaner;
a supply tank spaced rearwardly of the recovery tank and at a lateral side of the portable extraction cleaner, the supply tank configured to be received and supported by the supply tank cavity of the intermediate portion of the main housing in a vertical direction, the supply tank having portions that at least partially defining at least one of the top side and a first lateral side of the portable extraction cleaner; and
a battery pack spaced rearwardly of the supply tank and supported by the main housing at a rear side of the portable extraction cleaner opposite the front side,
wherein the front portion of the housing body is adjacent to the front side of the portable extraction cleaner.

2. The portable extraction cleaner of claim 1 , wherein
the front portion of the main housing has an upwardly facing horizontal platform positioned at a lower end of the front portion, and
the recovery tank is removably supported on the platform in a vertical orientation.

3. The portable extraction cleaner of claim 2 , wherein
the rear portion of the main housing opposite the front portion defines a battery compartment at an upper end of the rear portion, the battery compartment configured to receive the battery pack along a vertical insertion axis and to support the battery pack in a vertical orientation.

4. The portable extraction cleaner of claim 3 , wherein
the supply tank cavity is at an upper end of the intermediate portion.

5. The portable extraction cleaner of claim 1 , further comprising:
an extractor handle coupled on top of the main housing and extending along a front-to-rear longitudinal axis of the portable extraction cleaner.

6. The portable extraction cleaner of claim 5 , wherein
the extractor handle has a first end and a second end opposite the first end,
the first end of the extractor handle is coupled to the top side of the main housing and
the second end of the extractor handle is coupled to the main housing on a top surface of a support member that projects forwardly at an upper front end of the main housing.

7. The portable extraction cleaner of claim 1 , further comprising:
a cleaning tool in fluid communication with the recovery tank; and
a tool holder coupled to the main housing and configured to releasably hold the cleaning tool in a storage position with a longitudinal axis of the cleaning tool oriented in a horizontal direction along a front-to-rear longitudinal axis of the portable extraction cleaner.

8. The portable extraction cleaner of claim 1 , wherein
a rear portion of the body of the main housing defines a battery compartment at an upper end of the rear portion, the battery compartment configured to receive the battery pack along a vertical insertion axis and to support the battery pack in a vertical orientation.

9. The portable extraction cleaner of claim 1 , further comprising
a pump in fluid communication with the supply tank and operable to supply cleaning liquid from the supply tank;
a suction source in fluid communication with the recovery tank and operable to draw recovered liquid and dirt into the recovery tank; and
a base configured to support the suction source and the pump.

10. The portable extraction cleaner of claim 9 , wherein the main housing is mounted on the base and housing the suction source and the pump, the main housing configured to removably support the recovery tank and the supply tank.

11. A portable extraction cleaner comprising:
a main housing including a housing body that defines a front portion having an upwardly facing horizontal platform positioned at a lower end of the front portion, a rear portion, and an intermediate portion coupled between the front portion and the rear portion, the intermediate portion defines a cavity;
a supply tank removably supported in the cavity in a vertical direction, the supply tank having portions at least partially defining at least one of the top side and a first lateral side of the portable extraction cleaner;
a recovery tank removably supported on the platform in a vertical orientation, the recovery tank having portions at least partially defining a front side and a top side of the portable extraction cleaner; and
a battery pack supported by the main housing at the rear portion of the housing body opposite the front portion wherein the front portion of the main housing is adjacent to the front side of the portable extraction cleaner.

12. The portable extraction cleaner of claim 11 , wherein
the rear portion defines a battery compartment at an upper end of the rear portion, the battery compartment configured to receive the battery pack along a vertical insertion axis and to support the battery pack in a vertical orientation.

13. The portable extraction cleaner of claim 11 , wherein the supply tank is spaced rearwardly of the recovery tank.

14. The portable extraction cleaner of claim 13 , wherein
the supply tank cavity is at an upper end of the intermediate portion.

15. The portable extraction cleaner of claim 13 , further comprising
a pump in fluid communication with the supply tank and operable to supply cleaning liquid from the supply tank;
a suction source in fluid communication with the recovery tank and operable to draw recovered liquid and dirt into the recovery tank; and
a base configured to support the suction source and the pump.

16. The portable extraction cleaner of claim 15 , wherein the main housing is mounted on the base and housing the suction source and the pump, the main housing configured to removably support the recovery tank and the supply tank.

17. The portable extraction cleaner of claim 11 , further comprising
an extractor handle coupled on top of the main housing and extending along a front-to-rear longitudinal axis of the portable extraction cleaner.

18. The portable extraction cleaner of claim 17 , wherein
the extractor handle has a first end and a second end opposite the first end,
the first end of the extractor handle is coupled to the top side of the main housing and
the second end of the extractor handle is coupled to the main housing on a top surface of a support member that projects forwardly at an upper front end of the main housing.

19. The portable extraction cleaner of claim 11 , further comprising
a cleaning tool in fluid communication with the recovery tank; and
a tool holder coupled to the main housing and configured to releasably hold the cleaning tool in a storage position with a longitudinal axis of the cleaning tool oriented in a horizontal direction along a front-to-rear longitudinal axis of the portable extraction cleaner.

20. A portable extraction cleaner comprising:
a main housing including a housing body that defines a front portion, a rear portion, and an intermediate portion coupled between the front portion and the rear portion, the intermediate portion defines a cavity;
a recovery tank supported by the main housing, the recovery tank having portions at least partially defining a front side and a top side of the portable extraction cleaner; and
a supply tank spaced rearwa
