The product is much better than the previous version. The shape modification to something like Neato has certainly helped in corners. Does a better job on carpets than i7+. I like the product over all, But I cut 1 star because it never starts its scheduled job. Every morning it fails. i have to manually pull it out of the doc. Put it on the flat floor and hit start. There are still some kinks that can be corrected, The price is very high also.
