Before him, he owned the very first version of this vacuum cleaner. It worked amazingly, never had any glitches or problems. That is why I chose the new Mop 2 Pro vacuum cleaner, and was extremely disappointed. The vacuum cleaner constantly annoys with its crooked software: when choosing zone cleaning, it is not possible to add the number of passes. This feature was in the very first and simplest model, but it is not in the Pro. What kind of nonsense? But these are trifles, but what really pisses me off is when, during cleaning, he gets lost in space, stops orienting himself and hits the wall. The docking station cannot be found on command. The map is somehow strangely mirrored and some kind of game is drawn. You have to reboot it and carry it back to the docking station, start cleaning again from the beginning. Well, what for asks him these show-offs in the form of Lidar? In general, the vacuum cleaner disappointed, the software was written by complete degenerates, I will never buy Mi vacuum cleaners for myself again. The firmware is the latest, if anything.
