Introduction: High-pressure spray guns are not something that can be purchased casually; choosing the wrong one can damage the vehicle and lead to wasted time. Power, water pressure, flow rate, and nozzle design all impact the performance. For home use, a 2000W power and 120-200 Bar water pressure is sufficient, but for commercial use, higher specifications are required. Complete accessories, self-priming function, and durable materials are essential features to consider when making a purchase.

High-pressure washing is a technology that uses high pressure washer to generate strong pressure water flow for flushing and cleaning. It has the characteristics of deep cleaning, high efficiency and time saving, environmental protection and hygiene, and has been widely used in various aspects of environmental sanitation and cleaning operations. In recent years, in order to continuously improve the quality of the urban environment and create the "cleanest city", the Qingdao Municipal Administration Bureau has shifted its thinking from "sweeping" to "flushing", making full use of high pressure washing technology to inject stronger "water power" into sanitation operations.
