I finally gave in and purchased a robot vacuum cleaner after wanting one for such a long time. I chose according to reviews, decided to take a little more than the planned budget and got the result with a margin) Its power is very decent, it vacuums cleanly. The furniture does not become damaged, does not accidentally bump into it, lightly touches it, and navigates around it. Easily manageable with a mobile app. I have not come across any negative aspects as of yet, and I really hope that I won't.
