ABSTRACT:
A cleaner has in a tank a vacuum pump protected by a float valve above the maximum possible water level and a submersible pump at the bottom and both of these in the tank produce a vacuum for the suction of water against the vacuum, the submersible pump moving the filtered water collected in the lower region of the tank out of the tank past a check valve. The vacuum pump is constructionally combined with a tank cover, so that it can be mounted on differently constructed tanks for different cleaning functions. For wet suction purposes, the associated paper filter bag has a passage opening for the suction connecting pieces, so that the water to be filtered passes through the filter from the inside to the outside.
