The cleaning principle of the high-pressure jet washing machine is to use high-pressure water jets to rinse dirt and impurities from the surface of objects. The pressure of the high-pressure water jet can reach several to hundreds of megapascals, offering powerful impact and cleaning capabilities. The high-pressure water jet can effectively remove oil, dust, sand, and other dirt from the surface of objects, yielding significant cleaning results. Additionally, it can strip off surface adherents, acting as a rust removal and surface anti-corrosion coating removal tool.

The high-pressure spray washing machine has a wide range of applications. Firstly, it is extensively used in the automotive repair field. In vehicle repair, the surface of the car often accumulates a large amount of dust, oil, and mud, which not only affects the car's appearance but also reduces its performance. With the high-pressure spray washing machine, it is easy and quick to clean the dirt from the car's surface, enhancing the overall quality and performance of the vehicle.
