ABSTRACT:
A suction head for a vacuum cleaner includes a rag roll device which is wetted to perform a wet wiping action across the floor. The rag roll device is mounted for rotation about a horizontal axis. A rotation regulating mechanism, comprised of a pawl device and ratchet teeth, is provided which prevents the rag roll device from rotating when the suction head is moved forwardly, while permitting the rag roll device to rotate by a predetermined angle when the suction head is moved rearwardly. This enables different portions of the rag roll device to assume a floor-contacting position.
