All in all, a great vacuum cleaner! Previously, there was a regular one, with five modes, which randomly rushed around the room. To be clean, I had to run it for 40 in each room. This one cleans the hall in 10 minutes, and the nursery in 7! A minimum of unnecessary movements, even in a cramped corridor. After the first pass, he drew a map of the apartment and he almost exactly divided it into rooms. It was possible to leave it like that, but I corrected it a bit, put a limit on the place of the cat's bowl, and now you can safely run it all at once throughout the apartment! Before buying, I studied the characteristics and reviews for a long time and, I think, did not lose. Definitely recommend!
