4. Introduction
• Today car wash system is shifted towards
automation from manual.
• These systems are costly and require periodic
maintenance.
• Pakistan is an under developing country where
people cannot afford much cost of car wash.
• This design will be low cost and efficient car wash
system, which does not require periodic
maintenance.
• This system will be purely electronic and
motorized not hydraulic.
6. Why Automatic Car Wash System
We are going to design this system because we
have following benefits from this system.
• To save the time of operation.
• To save the cost.
• To save the cars from rashes.
• To increase the efficiency.

8. Working
Vehicle stops on car moving
platform
Presence sensor detect the car
and motor drive the conveyer
belt
As car move forward on
conveyer belt a sensor detects
and water & soap is sprayed
on car respectively
At Next station another sensor
when detects the car and 3
brushes one at top and 2 on
sides starts rotating
After that at next station
another sensor when detects,
the rinsing process will
happen
Then car will be moved on
next station as conveyer belt
continuously moving.
At next station 5th sensor
detects the car and dryer
starts for drying purpose
Then last sensor that will be
placed at the end of conveyer
belt if detects the car then
conveyer belt will stop.
When conveyer belt stops
then a green light will turn on,
which indicates the driver that
washing process is completed
and you are free to go .
