Abstract:
We find that car wash workers find it difficult to clean the undercarriage of the car, so the bottom surface
of the car couldn’t be cleaned, which will lead problems to the car. If left dirty, the undercarriage car
components will be easily damaged such as leaky and rusty. Our purpose in creating this product is to
solve the problem of washing the undercarriage of the car. We can achieve the objectives of the study,
which is cleaning the surface below more effectively compared to the existing products, can save time to
wash under vehicles where regular car wash takes 15 minutes, while our products can save time within
10 minutes. After we surveyed 20 respondents, they said that there was a problem to wash the
undercarriage of vehicles because they do not have the suitable equipment. After doing research, we
found that the materials that need to be used in carrying out our project are using copper flat nozzle,
copper lance adapter, steel pipe, as well as wheels and water jet. We can improve the iron pipes that need
to be flexible to make it easier for workers at the bottom of the car surface.
