Labor shortages and longer waiting queues have become major headaches for commercial car wash operators worldwide. To help business owners boost capacity while maintaining scratch-free cleaning quality, Shinewash officially launches our brand-new dual-arm touchless car wash machine.

Built on our mature touchless washing technology, this upgraded model delivers faster cycles, more uniform coverage and higher daily throughput, perfectly suited for high-traffic 24/7 unattended car wash sites.

What Is a Dual-Arm Touchless Car Wash Machine?

The dual-arm touchless car wash machine is an advanced brush-free automatic washing system equipped with two independent robotic spray arms. Unlike traditional single-arm equipment with only one moving spray unit, the dual-arm design enables synchronous cleaning on both sides of the vehicle.

Without any brushes or physical contact with car paint, it relies on high-pressure water and professional cleaning chemicals to remove dirt, brake dust, road grime and bug residues. The whole automatic workflow includes pre-soak, high-pressure contour washing, wheel & hub cleaning, wax coating, spot-free rinse and air drying. It supports sedans, SUVs, MPVs, pickup trucks and most mainstream vehicle types.

How Does the Dual-Arm Touchless Car Wash Work?

1. Vehicle scanning & positioning
   Ultrasonic and laser sensors quickly detect the vehicle’s size, height and body contour after the car parks in the bay, generating a 3D outline for customized washing routes.
2. Dual-arm synchronous operation
   Two spray arms run independently and simultaneously along both sides of the car. The arms adjust distance and spray angle in real time to follow body curves, covering rocker panels, doors, windows, bumpers and wheel hubs at the same time.
3. Full automatic wash sequence
   Chemical pre-soak → high-pressure main rinse → targeted wheel/hub washing → water wax application → purified spot-free rinse → contour air drying.
4. Cycle completion & reset
   Once finished, the arms return to standby, ready for the next vehicle automatically without manual intervention.
