    摘要： 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).

    摘要： A robot-like machine (10) for treating a surface area (33) within a boundary perimeter (31) (such as cleaning a carpet within a room) is guided using data developed from a graphic depiction representing the area (33). The graphic depiction may be for example, a blueprint (29). The machine (10) includes a self propelled chassis (75) having a working head (73) such as a vacuum nozzle (73b) mounted on it. A computing section (65) provides signals causing the machine (10) to move across the surface area (33) and a position sensor (69) generates a feedback signal representing the actual position of the machine (10). The computing section (65) is arranged for processing graphic data and the feedback signal and responsively generating command signals directed to each motor module (67). The machine (10) is capable of selectively treating portions of the surface area (33) such as those portions which become soiled more quickly.

    摘要： An accessory tool (10T) usable with an extraction cleaner (12, 120, 220) for cleaning a surface (11) includes a tool body (10), fluid reservoir (54), and porous spray bar (55). The tool body (10) defines a fluid pathway (50), an airflow pathway (52), and a suction nozzle (20) connected to the airflow pathway (52), and connects to the extraction cleaner (12, 120, 220) via an accessory hose (13). The fluid reservoir (54) is in fluid communication with the fluid pathway (50) and carried by the tool body (10). The porous spray bar (55), which is coupled to the tool body (10) adjacent the fluid reservoir (54) and surrounded by the suction nozzle (20), directs cleaning fluid (34) from the fluid reservoir (54) onto the surface (11). The fluid pathway (50) connects via the accessory hose (13) to a fluid delivery system (30) aboard the extraction cleaner (12, 120, 220) to receive the cleaning fluid (34) and direct the cleaning fluid (34) to the fluid reservoir (54). The airflow pathway (52) connects the suction nozzle (20) via the accessory hose (13) to a fluid recovery system (18) aboard the extraction cleaner (12, 120, 220).
