My first robot vacuum cleaner, no complaints, works for you and for you like a cute little Chinese cleaning manager. It’s a pity without wet cleaning, but it still does a lot for its money. It teaches where which rooms are, then you can ask to vacuum a specific room. For those who have never had a robot vacuum cleaner: if you have a lot of wires on the floor and things in general - either you have to clean up, or the robot vacuum cleaner is not for you - it will get confused, swear or bypass. Ridiculously drives to the base, wagging its back. It knows how to call on one carpet, but not on the other, perhaps because it is dark gray and the vacuum cleaner perceives it as an abyss. I will shamanize with gluing sensors. Nevertheless, I recommend buying it, the thing is really pleasant, it saves nerves and time for something more interesting, for example, watching a "dinner party".
