The Road Sweeper Cleaning Truck sweeps the debris to the specified position by the disc brush, and uses the high-pressure fan of the dust suction system to generate a high-speed airflow, which forms a strong negative pressure in the hopper, and sucks the debris into the garbage hopper. The whole process sprays water to reduce dust. The functions of water, sweeping, inhaling garbage, and automatic unloading are widely used in cleaning and cleaning operations in urban roads, squares, airports, stadiums, docks, schools, and other places.
