<p>Apparatus (10) for agitating a cleaning agent into a carpet comprises a housing (16) within which a first and a second roller (76f, 76r) are each mounted for rotation in a first angular direction. A platen (112) is mounted intermediate the rollers (76f, 76r). A belt agitator (134) comprising a fabric substrate (134f) having a pile surface (134p) is trained about the first and second rollers (76f, 76r) and extends under the platen (112). The rollers (76f,76r) and the platen (112) support rectilinear movement of the belt agitator (134) in the first direction (138) to bring a portion (140s) of its surface sequentially from a first position (140a) within the housing (16) to a contacting position (140b) in which the portion of the surface is in agitating contact with a carpet and, thereafter, to a second position (140c) within the housing (16).</p> |
