Pros: The Roomba i7 has almost no cons. It vacuums well. It should be according to the cleaning schedule, everything is strictly sweat time. Brushes perfectly collect both long hair and any small debris. Cons below: I would not classify it as a minus, but ours likes to drive several times in all places. It seems to have cleaned everything, but it goes and checks. I've seen this on every model from this company. In general, it’s not scary, on the contrary, cleaning is better.
