In the non-fuel business of a petrol station, car washing has become a proven traffic driver. Tianyi has delivered and installed a nine-brush tunnel automatic car wash machine at a Jinan petrol station. The hardware upgrade and smart integration link fuelling and washing seamlessly, so peak-hour queues are no longer a headache.

Compared with a conventional car wash machine, the key feature is nine-brush surround cleaning:
- 360° coverage with no blind spots: three top brush groups follow the roof and bonnet curves, while six side groups trace the body’s waistline. Whether it is a high-riding SUV or a streamlined saloon, the nine brushes stay close to the surface and lift mud from the wheel arches.
- Tunnel conveyor: instead of the stop-start motion of a reciprocating machine, a track pulls the vehicle through. The driver simply drives in slowly and the equipment moves the car along. The wash rhythm is continuous and the cycle is cut to about two minutes, greatly reducing congestion at the station exit.
For the petrol station, the machine acts as a quiet traffic builder. The Tianyi nine-brush tunnel machine is designed around efficiency, stability and site fit, and provides a tailored solution for high-traffic sites such as petrol stations and motorway service areas. If you are upgrading a wash service, the Jinan station’s choice is worth considering: professional equipment that turns traffic into retained customers.
Higher repeat visits: drivers wash while refuelling, and average dwell time falls to about five minutes. Many become repeat customers because the wash is fast and clean.
Lower costs: automatic operation reduces the need for two to three staff, and water and electricity use is 15% lower than conventional equipment.
Better word of mouth: customer Ms Li said, “I used to queue half an hour for a wash. Now it is done while I fill up, and the car looks bright.”
