Dynamic grid section and sattic grid section can work automatically and alternately for them to accept the blocked drifters, as stepping stairs, gradually move upward to the discharging port and then to clean them out of water. The step grid cleaner is a typical kind of fine grid and mainly used in various water-supply and sewage engineering. It is suitable in the places where the well depth is shallower; the width is less than 2m and it can avoid jamming and twining from drieters. There is no drive under water so it is reasonable in structure and long in service life.
