ABSTRACT:
A device for enhancing removal of liquid from fabric, such as a vacuum head device for removing liquid from carpet, includes a first and second surface forming an extraction slot. The first surface may include a plurality of channels extending towards the extraction slot configured to direct the liquid toward the extraction slot. Alternatively, the first surface may have a smaller surface area and the second surface may be configured with a lower surface in order to penetrate the carpet and act as a squeegee. The cross-sections of the first and second surfaces are preferably circular. In another embodiment, the cross-sections of the first and second surfaces may comprise, but are not limited to, a semi-rectangular cross section, a V-shaped cross-section, or an elliptical cross-section.
