Generally, when using a high pressure cleaning machine for cleaning operations, it is necessary to understand the characteristics of the high pressure cleaning machine to achieve a better cleaning effect. The cleaning process of a high pressure cleaning machine includes four basic elements, which are: pollutants, medium, substrate and cleaning force. However, the question we are most concerned about is-what is the effect of the high-pressure water flow cleaning produced by the high pressure cleaning machine? Because this directly affects our work efficiency. So what directly affects the cleaning effect of the high pressure cleaning machine? In fact, what directly affects the cleaning effect is the force acting on the object to be cleaned. In addition, the factors that have an important impact on the cleaning effect include the following aspects, which are:

　　(1) Hydraulic parameters also have a huge impact on the cleaning effect.

　　(2) The selection of the working parameters of the high pressure water jet produced by the high pressure cleaning machine directly affects the cleaning effect.

　　(3) The nature of the material to be cleaned also affects the cleaning effect.

　　(4) The degree of grinding and cavitation also has a non-negligible effect on the cleaning effect.

　　(5) The cleaning effect of the high-pressure water jet itself, the velocity obtained through the nozzle, the impact force on the object to be cleaned through the conversion of kinetic energy, and the sum of the common force generated by the interface flow of the fluid on the object to be cleaned, etc.

　　From this point of view, there are actually many factors that affect the cleaning effect of the high pressure cleaning machine, but this does not directly affect the possibility of us improving its work efficiency. As long as we can grasp the crux of the problem, our cleaning effect is bound to improve a lot.
