Car beauticians usually use high-pressure washers when washing vehicles. This equipment is favored for its high efficiency and powerful cleaning ability. The high-pressure washers commonly used by car beauticians in their work include air compressors and nozzle-type washing equipment. Air compressors are the main pneumatic source in car beauty shops. When washing cars, nozzle-type washing equipment uses high-pressure water flow to wash cars. In addition, there are other types of washing equipment, such as roller brush low-pressure washing equipment, but they are less used in the field of car beauty.
