ABSTRACT:
A water supply hose has one or more jets operable to maintain that part of the supply hose which is upstream from the jet in tension, the supply hose having its free end supported by a surface float. Another length of hose smaller in diameter extends from the float in line with the larger-diameter water supply hose, the other hose terminating also in a surface float and having a jet disposed adjacent the latter float to maintain the smaller-diameter hose normally under tension. Alternatively, a length of the water supply hose upstream from the first mentioned float may be made of smaller diameter than the balance of the water supply hose and this smaller-diameter portion is then provided with a drive jet adjacent the float adapted to keep the smaller-diameter portion of the hose under tension. The cleaner may be or may not be provided with one or more cleaning hoses.
