Multi-purpose high pressure washer hose is a type of hose used for high pressure water cleaning and is widely used in various industrial and cleaning applications. This hose pressurizes water through a high-pressure pump or booster, and then converts the high-pressure, low-flow rate water into a low-pressure, high-flow rate jet through a high-pressure nozzle to achieve efficient cleaning of the surface being cleaned.

A washer hose adapter is an accessory used to connect a high pressure washer to a hose, ensuring a safe and effective connection between the two.
