Device for improved removal of liquid from fabric
DC CAFCFirst Claim
1. A vacuum head device for removal of liquid from a fabric, comprising:
- a leading portion coupled to the device and configured to penetrate the fabric;
a trailing portion coupled to the device and configured to penetrate the fabric;
an extraction slot formed between the leading portion and trailing portion wherein the leading portion includes a plurality of channels extending from a leading surface of the leading portion to a trailing surface of the leading portion, and the plurality of channels are configured to be in direct physical communication with the fabric when the device is in operation.

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.

21. A vacuum head device for removal of liquid from a fabric, comprising:
-
the first member coupled to the vacuum head device and configured to be proximate the fabric when in use; a second member coupled to the vacuum head device proximate the first member and configured to penetrate the fabric; an extraction slot defined by the first and second members, and configured to enable extraction of liquid from the fabric; a first and a second contact point, each extending from the first member and each configured to be in direct physical communication with the fabric when the device is in operation, neither contact point on a line orthogonal to the first member; and a channel between the first contact point and the second contact point, the channel configured to be in direct physical communication with the fabric when the device is in operation. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A vacuum head device for removal of liquids from a fabric, comprising:
-
a trailing member coupled to the vacuum head device, configured to penetrate the fabric, and having a shape that substantially traverses an intended direction of use of the vacuum head device; a leading member coupled to the trailing member thereby forming an extraction slot between the trailing member and the leading member, configured to penetrate the fabric, and having a shape that substantially traverses an intended direction of use of the vacuum head device; and a channel extending through the leading member and configured to be in direct physical contact with the fabric when the vacuum head device is in operation, wherein the channel is oriented substantially parallel to a direction of use thereby permitting liquid in the fabric to traverse the leading member. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36)
