Exiting a Auto Car Wash which is a facility used to clean the exterior of motor vehicles. SCO 10,519.
Some car washes have their customers pay through a computerized POS, or point of sale unit, also known as an "automatic cashier", which may take the place of a human cashier. The mechanism inputs the wash PLU into a master computer or a tunnel controller automatically. When the sale is automated, after paying the car is put into a line-up called the stack or queue. The stack moves sequentially, so the wash knows what each car purchased. After pulling up to the tunnel entrance, an attendant usually guides the customer onto the conveyor. At some washes, the system will send the correct number of rollers automatically, based on tire sensors. The tire sensor lets the wash know where the wheels are and how far apart they are. On other systems the employee may guide the customer on and press a 'Send Car' button on the tunnel controller, to manually send the rollers which push the car through. Following the idle zone and/or high pressure arch (if applicable) is the friction zone. In the friction zone, a variety of brushes are used to clean all of the vehicle's surfaces. Wrap-around brushes (wraps) clean the front, sides, and rear of a car. A set of wraps consists of two offset brushes which are attached to overhead arms which are generally mounted over the center of the tunnel. Some wrap-around brush designs use jointed side-mounted arms to increase the brush's front and rear contact time. Wraps typically rotate with the vehicle's direction of travel. Some wrap-around brushes are capable of switching direction while cleaning the front of a car to prevent customers' license plates from being bent. Wraps are supplemented by side brushes (ranging in size from 18 inches [45 cm] up to 63 inches [160 cm] tall or higher). Side brushes may be either top or bottom mounted.
