Working Principle of Self-service Car Washing Machine
Aug 23 2021

The self-service car washing machine operates with an intelligent main control system, high-pressure water pump, automatic chemical proportioning system and coin / QR code payment system.


After users start the machine by scanning code or inserting coins, the main controller receives instructions and switches functions automatically: high-pressure water rinsing, foam spraying, clean water flushing and wax coating. It also integrates vacuum cleaning and ozone disinfection. Users manually control the water gun and foam gun freely. The system charges by time with countdown deduction and stops automatically when time is up, realizing 24-hour unattended self-service car washing.
