ABSTRACT:
Submersible displacement apparatus 10 for periodically displacing a submersible suction cleaner connected to a suction source by a suction hose is disclosed. The apparatus 10 comprises a body 11 defining two converging flow passages 12 and 16 therethrough. Flow passage 16 is connectable in the hose with outlet 14 communicating with the source. Flow passage 12 at its inlet has a valve 17 for periodically opening and closing that passage. An actuation mechanism driven by water wheel 28 is provided for opening and closing valve 17. An impeller is rotatably mounted in passage 12 to drive propeller 20 when water is admitted through valve 17 thereby periodically to exert a displacement force on the body and therefore also on the suction cleaner.
