Product principle of car wash water gun

The high-pressure water gun device makes the high-pressure piston pump generate high-pressure water to wash the surface of the object. The impact force of water is greater than the adhesion between dirt and the surface of the object, and the dirt is stripped and washed away by high-pressure water, thus realizing the cleaning device for cleaning the surface of the object. Because the high-pressure water column is used to clean dirt, unless it is stubborn oil stains, it needs to add a little detergent, otherwise the foam generated by strong water pressure is enough to take away ordinary dirt.
