A high-pressure washer uses a power unit to drive a high-pressure plunger pump, generating high-pressure water to wash the surface of an object. The impact force of the water is greater than the adhesion between the dirt and the object's surface, causing the high-pressure water to peel off and wash away the dirt, thus cleaning the surface. Because it uses a high-pressure water jet to clean dirt, unless it's a very stubborn oil stain, the foam generated by the strong water pressure is sufficient to remove most dirt. Therefore, high-pressure cleaning is recognized worldwide as one of the most scientific, economical, and environmentally friendly cleaning methods.
Based on the water temperature, high-pressure washers are divided into two main categories: cold water high-pressure washers and hot water high-pressure washers. The biggest difference is that hot water washers include a heating device, typically using a combustion chamber to heat the water. Using hot water can quickly rinse away large amounts of dirt and oil stains that are difficult to remove with cold water, significantly improving cleaning efficiency. However, because hot water washers are often more expensive and have higher operating costs (due to the need for diesel fuel), most users still choose ordinary cold water high-pressure washers.
