Review on 🧹 iRobot Roomba i7+ (7550) Robot Vacuum with Auto Dirt Disposal - Wi-Fi Connected, Smart Mapping, Alexa Compatible. Designed for Pet Hair, Carpets, Hard Floors - Black by Nguyn ng Qun  (D Nhn ᠌

I will describe the problems that I encountered. 1. Can move out of the docking station and just stand stupidly for 5 minutes 2. Not all rooms are cleaned, he does not even reach them 3. Can enter the room and remove 10% and leave 4. The cleaning algorithm is completely incomprehensible 5. During the study and memorization of the rooms, it is necessary to turn on the light in all the rooms, while the robot can enter one room and return to the docking station. 6. When opening the package, I did not find a single document (maybe I got a used one, visually it looked like it was new)
