<p>The invention relates to an apparatus for extracting a liquid e.g. shampoo, from a wetted carpet, and which is generally suitable for incorporation in a carpet shampooing device which wets the carpet prior to shampoo removal and partial drying thereof. In particular the invention provides an apparatus for extracting liquid from a wetted carpet by blowing gas through the carpet, which comprises a gas duct 10 for blowing gas through the carpet 8 and which has a gas exit slot 2 at a lower end thereof; a discharge duct 11 for discharge of a gas/liquid mixture from the carpet and having at a lower end an entry slot 3 adjacent the gas exit slot and at an upper end communicating with a liquid container 5; the discharge duct having an overall cross-section substantially the same as the cross-section of the entry slot, and being divided into a plurality of separate upwardly extending channels 1; each channel having a base which is curved in crosssection; and the channels being inclined at an angle not greater than 60.degree. with respect to the horizontal. Preferably, the channels are inclined at substantially 45.degree. to the horizontal to obtain efficient transport of liquid up the channels into the container. The channels preferably have a base portion of semi-elliptical cross-section.</p> |
