Some pros: We bought it as a present for my mother, she is extremely happy - she squeaks every time she turns it on with tenderness. The vacuum cleaner works both with the help of a button on the robot itself, and with the help of the application. He pronounces all his actions from the series: “finished cleaning”, “recharging”, etc. Don't fall down the stairs! This, I think, is a huge plus, he “sees the boundaries” and calmly walks near the stairs, but does not go out onto it. The set with the vacuum cleaner contains several cloths for wet cleaning, as well as all the brushes for dry cleaning. Also a huge plus in the piggy bank of this robot is that it works in a house with animals and quite successfully. He collects all the wool with a bang. It has been 5 months since the purchase, so we recommend it for the whole family! Got cons: He does not have the ability to build a map of the premises, sometimes he can drive over one place several times. There were also cases when he missed and did not get up to the station immediately, but corrected himself.
