Great rob for 20k. It builds a map well, it is possible to build walls, choose areas for cleaning. The charge is enough to clean 120 squares without carpets. Compared to the previous model without lidar, it’s a delight, it doesn’t poke into obstacles like a blind kitten, it doesn’t get lost, it always immediately finds a charging station, due to this it goes to the cleaning for 10% of the charge. Wet cleaning is rather weak: the water container is small, the strip is not the entire width of the robot, dry places remain on the sides and in the middle.
