The concept of an automated vehicle washing system is among the most significant applications that automotive engineering has to offer. Lack of time prevents most people from washing their cars properly. Moreover, a chemical washer is an indispensable part of a vehicle. Consequently, we have developed a system that utilizes the Internet of things to automate the automobile washing process. To submit an HTTP request to the server, the system will first establish a connection with an Internet of Things module. Once it is complete, it retrieves the system variable from the server and places it into an Android application. The user can exercise control over the whole vehicle washing system from inside that application. The primary objective of this system is to lessen the amount of manual labor that is required for the vehicle wash system. A user can wash many vehicles at the same time with this technology. Therefore, the most significant innovation of this vehicle washing system is its ability to reduce human involvement in the car-washing process. Data output is what the Android app shows. This will save both time and money.
