Well, I am very pleased with the robot, what a cleaning assistant. Pros: 1. Very accurately builds a map of the room 2. Doesn't crash like crazy into walls or nightstands. And it drives smoothly. 3. Cleans the room several times. And then just go to another. Has cons: 1. It was difficult to connect (you need wi-fi 2 GHz, but I tried to connect to 5, well, this is already my cant) 2) And I don’t know how to flash a vacuum cleaner on iPhones so that I can speak 2022.
