Jining bus company in Shandong has completed a small innovation: two Tianyi automatic car wash machines and two self-service car wash units are now operating in an idle area of its depot, offering affordable washing to local drivers. The move puts underused space to work and gives the bus company a stable new income stream, a win for public service and for revenue.

The company operates several depots. Outside bus scheduling, many parking spaces and time slots sit idle. To improve utilisation, the company targeted the common complaint that car washing is hard and expensive, and decided to offer a public wash service from the spare space. The model combines fast automatic washing with self-service detailing to meet different drivers’ needs and turn dormant space into active income.
- Two Tianyi automatic car wash machines: focused on speed and convenience. A car drives in and the machine runs the full rinse and dry cycle automatically; the main wash takes only a few minutes, which suits commuters and parents on the school run.
- Two self-service car wash units: focused on deeper cleaning, with a high-pressure gun, foam brush and interior tools. Drivers can clean seat gaps, wheels and other details themselves, which is popular with ride-hailing drivers and families.

Since the trial began, the wash area has handled more than 60 vehicles a day, with queues at peak times. “The automatic machine is fast; ten minutes after work and it’s done. The self-service unit lets me clean the interior, and the value is good,” said Mr Li, a driver who lives nearby. A manager at the bus company did the sums: “The equipment runs reliably and consumable costs are low. After water, power and maintenance, it brings a useful net profit each month, and it strengthens the depot’s service to the community.”
Tianyi car wash machines are built around site fit, reliable operation and value creation, and we provide customised wash solutions for companies, institutions, car parks and communities. If you want to put idle space to work and add a revenue channel, the Jining bus company’s approach is worth considering: professional equipment can turn an unused lot into a valuable asset.
