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 supply tank for holding cleaning liquid;
a recovery tank for receiving and storing recovered liquid and dirt;
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;
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 configured to removably support the recovery tank and the supply tank, wherein
the recovery tank is arranged at a front side of the portable extraction cleaner when supported by main housing, and
the supply tank is arranged at a lateral side of the portable extraction cleaner between the front side of the portable extraction cleaner and a rear side of the portable extraction cleaner when supported by main housing.

2. The portable extraction cleaner of claim 1 , wherein
the main housing includes a housing body that defines a front portion,
the front portion 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 , further comprising a battery pack electrically connected to the pump and the suction source, wherein
the housing body defines a rear portion opposite the front portion,
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.

4. The portable extraction cleaner of claim 3 , wherein
the rear portion defines one or more vent portions for venting cooling air entering and exiting the suction source.

5. The portable extraction cleaner of claim 3 , wherein
the housing body defines an intermediate portion coupled between the front portion and the rear portion,
the intermediate portion defines a supply tank cavity at an upper end of the intermediate portion, the supply tank cavity configured to receive and support the supply tank in a vertical orientation.

6. The portable extraction cleaner of claim 2 , wherein
the suction source includes a motor and an impeller, wherein the motor is supported on the base in a vertical orientation, and
the pump is supported in the housing body above the suction source.

7. The portable extraction cleaner of claim 6 , wherein
the motor is positioned along a motor axis, and
the pump is positioned along a pump axis that has an orientation transverse to the motor axis.

8. The portable extraction cleaner of claim 2 , wherein
the base includes a tank receptacle having a suction port fluidly coupled to the recovery tank when the recovery tank is supported by the main housing, and
the suction source includes a motor and fan assembly fluidly coupled to the recovery tank via the suction port.

9. The portable extraction cleaner of claim 8 further comprising:
a flexible hose for transporting recovered liquid and dirt from a surface to be cleaned to the recovery tank, wherein
a proximal end of the flexible hose is fluidly coupled to the suction conduit.

10. The portable extraction cleaner of claim 2 further comprising:
an extractor handle extending along a front-to-rear longitudinal axis of the portable extraction cleaner, the extractor handle having a first end and a second end opposite the first end, wherein
the first end of the extractor handle is coupled to a top surface of the housing body and
the second end of the extractor handle is coupled to the housing body on a top surface of a support member that projects forwardly at an upper end of the front portion.

11. The portable extractor cleaner of claim 10 , wherein the recovery tank is adjacent the first end of the extractor handle, and wherein the supply tank is adjacent a side of the extractor handle.

12. The portable extraction cleaner of claim 1 further comprising:
a cleaning tool in fluid communication with the pump and in fluid communication with the recovery tank; and
a tool holder coupled to the main housing or the base 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.

13. The portable extraction cleaner of claim 1 further comprising:
a cleaning tool;
a flexible hose fluidly coupling the cleaning tool to the recovery tank for transporting recovered liquid and dirt from the cleaning tool to the recovery tank; and
a conduit fluidly coupling the cleaning tool to the supply tank for delivering cleaning liquid from the supply tank to the cleaning tool, the conduit having one or more portions carried within the flexible hose.

14. The portable extraction cleaner of claim 1 further comprising:
a flexible hose for transporting recovered liquid and dirt from a cleaning tool to the recovery tank, wherein
the base includes one or more peripheral flanges disposed along a perimeter of the base proximate a bottom end of the base, the peripheral flanges configured to support one or more portions of the flexible hose when the flexible hose is wrapped around the base proximate the bottom end of the base.

15. The portable extraction cleaner of claim 14 , wherein
the one of more peripheral flanges include a plurality of peripheral flanges that define one or more access recesses between them, the one or more access recesses having beveled sides with a bevel angle greater than about 20 degrees.

16. The portable extraction cleaner of claim 1 , further comprising a battery pack electrically connected to the pump and the suction source, wherein
the main housing includes a housing body that defines a rear portion, and
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.
