There are a number of advantages to using a combination of touchless and brush technologies in a bus wash system:
The combination of touchless washing and brushes ensures that every part of the bus is washed effectively. Touchless methods can clean intricate or sensitive parts without physical contact, while brushes ensure a deep clean on surfaces that can handle and benefit from direct contact.
The combination is more thorough and ensures less time is spent washing vehicles.
The design of stationary brushes combined with touchless cleaning reduces the chance of damage to the vehicle.
