Abstract
An extractor comprises a foot assembly supported by at least one wheel at a rearward portion thereof and at least one rotatable agitator at a forward portion thereof, a fluid delivery system, a fluid recovery system and an extension with a first end aligned with an inlet for an extraction path and a second end in register with a surface to be cleaned. The foot assembly can be traversed over the surface to be cleaned in alternating forward and rearward movements. Movement of the foot assembly in a rearward direction supports the forward portion of the foot assembly on the extension in a first position and the at least one agitator and movement of the foot assembly in a forward direction shifts support of the forward portion of the foot assembly off of the extension in a second position.
Claims19
An extractor comprising:
- a foot assembly supported by at least one wheel at a rearward portion thereof and at least one rotatable agitator at a forward portion thereof, wherein the foot assembly is traversed over a surface to be cleaned in alternating forward and rearward movements;
- a fluid delivery system for delivering a cleaning fluid to the surface to be cleaned;
- a fluid recovery system for extracting fluid and debris from the surface to be cleaned through an extraction path to a recovery tank;
- and
- an extension with a first end aligned with an inlet for the extraction path and a second end in register with the surface to be cleaned;
- wherein movement of the foot assembly in a rearward direction supports the forward portion of the foot assembly on the extension in a first position and movement of the foot assembly in a forward direction shifts support of the forward portion of the foot assembly off of the extension in a second position;
- and
- wherein the extractor is an upright extractor having a handle assembly pivotally coupled to the foot assembly.
An extractor comprising:
- a foot assembly supported by at least one wheel at a rearward portion thereof and at least one rotatable agitator at a forward portion thereof, wherein the foot assembly is traversed over a surface to be cleaned in alternating forward and rearward movements;
- a fluid delivery system for delivering a cleaning fluid to the surface to be cleaned;
- a fluid recovery system for extracting fluid and debris from the surface to be cleaned through an extraction path to a recovery tank;
- and
- an extension with a first end aligned with an inlet for the extraction path and a second end in register with the surface to be cleaned;
- wherein movement of the foot assembly in a rearward direction supports the forward portion of the foot assembly on the extension in a first position and movement of the foot assembly in a forward direction shifts support of the forward portion of the foot assembly off of the extension in a second position;
- wherein in the first position the extension lifts the forward portion of the foot assembly to reduce the amount of contact that at least one of the at least one rotatable agitator has with the surface to be cleaned.
An extractor comprising:
- a foot assembly supported by at least one wheel at a rearward portion thereof and at least one rotatable agitator at a forward portion thereof, wherein the foot assembly is traversed over a surface to be cleaned in alternating forward and rearward movements;

- a fluid recovery system for extracting fluid and debris from the surface to be cleaned through an extraction path to a recovery tank;
- and
- an extension with a first end aligned with an inlet for the extraction path and a second end in register with the surface to be cleaned;
- wherein movement of the foot assembly in a rearward direction supports the forward portion of the foot assembly on the extension in a first position and movement of the foot assembly in a forward direction shifts support of the forward portion of the foot assembly off of the extension in a second position;
- and
- wherein at least one of the at least one rotatable agitator is in contact with the surface to be cleaned during the forward and rearward movement of the foot assembly.
