印度采购需求：洗车机、自动洗车机、单臂洗车机、非接触式洗车设备

I'm looking for information on car wash systems suitable for various vehicle types. Specifically, I need options that include both automatic and manual washing solutions, along with any additional features that enhance efficiency and customer experience. Please provide details on the different models you offer, including specifications, pricing, and bulk discount options. In addition to the systems themselves, I'd appreciate insights into the maintenance requirements, installation processes, and any training that might be needed for staff. I'm particularly interested in solutions that incorporate eco-friendly practices or water-saving technologies. If you could send over catalogs or brochures, that would be great! Looking forward to your prompt response.
