阿曼采购需求：免触摸

I'm interested in your latest touchless robotic car wash system. Could you provide detailed specifications and features? Specifically, I'd like to know about its performance efficiency, water usage, and maintenance requirements. Additionally, please include information on pricing, available models, and any bulk order discounts you might have. Also, if there are any optional accessories or upgrades, I'd love to hear about those too. Thanks!
