ABSTRACT 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 cross- section; and the channels being inclined at an angle not greater than 60° with respect to the horizontal. Preferably, the channels are inclined at substantially 45° 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.
