We already have an iRobot Roomba i7 at home. Mom every time she came to visit, she was surprised at the cleanliness. We decided to buy a robot for her, but we took a cheaper and a little simpler model, without building maps (she doesn’t need them). The rest is not inferior to i7+. Powerful, quiet, smart. The rollers are just as cool rubber, they collect garbage and tear off adhering rubbish just as well as the i7 +. Garbage also unloads itself into a bag at its base. I even think that we had to wait a bit with the purchase of a vacuum cleaner and take a new i3 + model))) It comes out much cheaper, though. Although they are very satisfied with their robot)
