How to Easily Turn On the Vacuum at the Car Wash
Most car wash vacuum systems are equipped with a sensor that detects when the nozzle is removed from its holder. So, to turn on the vacuum at a car wash, simply lift the nozzle of the hose from its holder, and the sensor will activate the suction motor. Once you have finished cleaning, press the stop button on the vacuum handle, return the hose to its holder, and the motor will shut off automatically.
