Abstract: A device for receiving and removing plastic, sludge-like materials deposited on beds of bodies of water. The device systematically senses the bottom of the body of water, suctions it off layer by layer, and independently moves along even if coarse obstacles are present. The device has at least one pump/compressor, at least one hydraulic unit and at least one electric power generator and is connected on one side to a disposal site or a settling basin or a transportable container on land and on the other side to the suction module by pipelines. The suction module moves along on the bottom independently by a special tracked chassis unit, is connected by a cable to an echo sounding emitter arranged floatingly above the suction module and/or to a GPS receiver, and has a pivoting arm, which independently adapts to the bed of the body of water and oscillates freely.
