ABSTRACT:
The inner circumferential surface of a suction pipe must be periodically cleaned as well as the inner region of the suction slit and especially the webs between the suction holes of the suction pipe. The aim of the invention is to facilitate said cleaning process. To this end, a standard cleaning spray gun is provided with a long cleaning lance comprising a rotor nozzle on the end thereof. In order to clean the suction pipe, said lance can be passed through a hole on the front side of the fixed suction pipe. The dirt released and the remaining suction water can thus be evacuated on the other front side in a problem-free manner.
