Contactless car washing machines are generally used in small car beauty shops, 4S stores, and other places. The installation area of Qingdao Risen Electromechanical's contactless car washing machine is 6.2 meters long, 4.55 meters wide, and 2.95 meters high. The general design structure of contactless car washing machines is relatively simple.

At present, contactless car washing machines in China are mainly divided into three categories: one is the prototype design based on the previous compound, and the car washing process is also reciprocating. The land area is slightly larger. The second type is the water axe car washing machine series. The third category is imported series car washing machines. Generally speaking, the swing arms of domestic car washing machines are mostly single swing arms, while imported car washing machines are mostly double swing arm car washing machines.

The contactless car washing machine mainly relies on high-pressure water to wash the entire body of the car, greatly saving time for cleaning the exterior of the car. Combined with simple manual cleaning and wiping, the cleaning effect is better. It does not come with a brush, dispelling customers' concerns about damaging the car paint. Additional products can achieve chassis washing, artificial intelligence, and automatic detection of the size of the car body.

The advantages of contactless car washing machines are mainly manifested in the following aspects:

（1） Ultra high car washing efficiency. The vehicle cleaning speed is fast, and only simple manual wiping is needed, saving time and effort.

（2） Safe and reliable. The contactless car washing machine adopts a high-pressure contactless cleaning mode to prevent the car paint surface from being scratched by sand particles, and has an automatic detection and protection function to truly ensure the safety of the car during cleaning.

（3） No scratches, no damage to the car paint: Avoid small scratches and damage to the paint surface caused by dust and gravel mixed in during the process of wiping the car body with a car cloth, sponge, or washing gloves, which can damage the transparent paint layer of the car body and cause scratches and damage to the paint surface.  

（4） Thoroughly clean: thoroughly clean any oil stains, dirt, mud, and surface oxides on the body, gaps, tire bells, and any other parts. Change the car washing method to clean the gaps, tire ring dirt, and surface oxide thickening phenomenon.

（5） Nursing effect: Most non-contact car washing machines are equipped with cleaning solution, wax water and other nursing ingredients. Each wash of the car can take care of the paint surface, making washing and waxing convenient and simple.
