A surface treatment device has a body 10 and a treatment head 18 for treatment of a surface by application of a treatment liquid from supply tank 20 and removal of at least a substantial portion of the liquid, passing it to recovery tank 22. At least a part of the treatment head 18 is detachable from the body of the device, and replaceable by a treatment head or part of a different configuration from that of the first head or part. The treatment head may be detachable as an assembly, and may be a cleaning head. Another aspect lacks the detachable treatment head and includes a suction source for creating an airflow through ducting 28, 30, 46 from the treatment head to a recovery tank which has a downwardly extending duct to convey suction airflow to the suction source. Another aspect lacks the detachable treatment head and the suction device but includes a handle 14 which it pivotally connected to the device body with a number of angular positions available and/or is extensible in respect to its length. This handle allows the user to move the device over the surface to be treated. Other components shown include cover 48, cover handle 50, device housing 26 and wheels 12 |
