In addition, the provision of a pre-cleaning unit allows not only ordinary sludge adhering to the underfloor of vehicles but also adhered substances such as chemicals (mainly calcium chloride) sprayed on the road as a snow melting agent during snowfall and mixed with these chemicals. The sludge strongly adhered to the surface can be easily removed because it is washed by jetting a high-pressure cleaning material after it is sufficiently moistened.
Also, since the device is small and has a simple structure, the installation place is not limited.For example, if it is installed near the entrance of the garage, the underfloor of the floor can be washed by not only during vehicle inspection maintenance but also daily when entering the garage. Reduces corrosion and significantly extends vehicle life. In addition, since the cleaning nozzle swings to perform cleaning, even a portion that is difficult to clean with the conventional device is not affected, and the cleaning can be efficiently performed.
