A new generation of suction nozzle cleaning machine adopts the unique mechanical design, using the hydrodynamic water fragmentation,producing very fine water mist,with the speed of sound (V=360m/s) to form a strong momentum jet to the suction nozzle,suction nozzle for cleaning at the top of the formation of a continuous field,crushing the internal surface of the dirt (the nozzle will not be damaged because of its independent device),during the cleaning process the cleaning liquid (deionized water or distilled water)can be achieved automatic direct emissions.
