Specifically, I would like to know about the different models available, their features, and how each one performs in various environments. It would also be helpful to understand their specifications, including the types of sensors they use, their efficiency in removing weeds, and any unique technologies they incorporate. Additionally, I'm interested in pricing details, minimum order quantities, and lead times for delivery.

Looking forward to your prompt response!
