The device for the particularly simple and effective cleaning of a stormwater tank (1) used for collecting and clarifying stormwater comprises a pipe frame (12) which is mounted so as to be capable of swivelling over the tank and has spraying nozzles (15) arranged on it. This pipe frame is connected to a pipeline (16) for the supply of pressurised cleaning water for cleaning both the base (2) of the tank and the walls (3, 4) of the tank. <IMAGE>
