The first experience of a robot vacuum cleaner. They were afraid to buy more expensive models, especially since there was a discount on this one. The device is worth its money - it vacuums 2 times a day, does not ask for a day off and does not grumble, but sometimes it falters and skips places. This model does not have a laser lidar (this is why the price is so high), so it does not bypass obstacles very confidently. An indispensable device if there is an animal in the house. In general, we recommend to buy.
