Purchased a cleaning robot from Ecovacs India. The worst customer service ever. After 4 reminders over 7 days, they still haven't sent me an invoice. They sent a guy for training but he didn't seem to know a lot. I had already installed and mapped my house but wanted to some something about the other functions. He kept manhandling the device, trying to annoyingly force stop it when the app was saying 'self cleaning in progress' - something which he had no idea about. The robot takes 30 mins to clean a room of 200 square feet because it keeps going over the same space again and again. So, it goes low on battery before it can cover the entire house. It's got the mapping right but every time I run it, it doesn't have a sense of what it has covered and what it has not. It's an average product with terrible customer support.
