How to choose a car pressure washer and how much does it cost?

Car pressure washers are a new generation of car cleaning tools. They use a high-pressure device to atomize water into fine water mist, which is then used to clean the car’s surface. The machine itself is less than one cubic meter in size, comes with a built-in battery, allows for easy movement over a wide area, and consumes very little water—only five to six liters per car.
