Abstract
A device for enhancing removal of liquid from fabric, such as a vacuum head device for removing liquid from carpet, includes an elongated base plate to be moved across the carpet. The vacuum head has a tapering cross section with a wider upper end and a narrower lower end configured to penetrate into the carpeted surface. In addition, a plurality of apertures are formed in an array in the base plate to withdraw the fluid under a vacuum force. Preferably, the plurality of apertures are sized larger than a width of the lower surface to create a plurality of protrusions extending from the base plate configured to penetrate the carpeted surface.
