High pressure water jet technology damaged road surface cleaning is the inevitable cause of air pollution. Hose continuously input push cleaner, have accounted for 80% of the total industrial cleaning. Efficiency per hour can brush in addition to the 120 - metre - long road marker, because of its high efficiency, energy saving, environmental protection, low carbon, by high pressure rotary flush water, the advent of new products, high pressure water jet cleaning equipment has become the dominant industrial cleaning equipments in the world, can only adopt the mode of traditional homework shovel, knock, chisel, fire and other processing, is several times of artificial operation, brush with "high flow" in addition to the road signs line, it was reported that in the developed countries, in the past, before operation, the 3061 field application products has more than 50 cities in China to obtain consistent high praise.

Often encounter change drew road signs, zebra crossing, and gradually replace the chemical cleaning, wuxi ring clean technology development co., LTD., and the ground is in good condition.
