“With an unattended car wash, the biggest fear is a machine scratching the paint and a stream of complaints. There is nobody watching, and one problem can damage your reputation.”
Mr Li, who works in the automotive aftermarket in Jinzhong, Shanxi, looked at six brands of automatic car wash machines before choosing Tianyi Longxishui. His 24-hour unattended shop has now been open for two months with no scratch complaints, and average monthly revenue is 25% above his forecast.

Mr Li’s shop is beside a residential community in Jinzhong and focuses on careful washing that does not damage paint. Two things mattered most when he chose equipment: no contact and smart operation. The Tianyi automatic touchless machine surprised him:
- Reciprocating rotating wash: high-pressure water and a dedicated foam cover the body, with no brush group touching the paint, removing the risk of grit trapped in traditional brushes scratching the surface.
- Smart sensing and avoidance: infrared sensors read the body outline and avoid protruding parts such as mirrors and antennas, so the vehicle is not damaged.
During installation, Mr Li spent two days on site: “I watched the workers commission it carefully. The water pressure was set so it removes mud spots without damaging the paint, and the foam ratio was adjusted three times to make sure it cleans well without leaving residue.” He was also impressed by payment compatibility: WeChat Pay, Alipay and UnionPay QuickPass are supported, so customers scan and wash, a smoother flow than manual service.
“My old staffed shop cost 7,000 yuan a month in wages alone. Now the machine does the work and I spend ten minutes a day checking the data.” Mr Li did the numbers: about 55 vehicles a day, utilities under 80 yuan, and net profit 35% higher than a staffed shop. Nearby drivers agree: “I didn’t want to use brushes on my new car. This touchless machine cleans well and gives me peace of mind, and I can come after a late shift.”

For an unattended car wash, equipment is the foundation. The Tianyi automatic touchless machine, with safe, scratch-free cleaning and smart unattended operation, lets owners move their attention from watching the machine to growing the business.
If you are preparing an unattended car wash, Mr Li’s choice is worth considering: the right equipment makes the business easier to run.
