Pay attention to the following data as they are very important when you read the review and look at the photos 8/18; The photo was taken today, Wednesday 22 August. I ordered this set because I thought that there is no way these items could differ from the original. I was wrong. To be fair, filters are just filters, and their fit and function are fine. The attached picture shows the wear after less than 6 hours of use on 60% parquet and 40% carpet. They have no ridges in the middle at all. The rollers I replaced had more burrs than this one after 1 year of use! The rotating edge brushes seemed to fit well, but once I put them in Roomba found them harder to rotate than the original brushes. Also, Roomba believes he is now in a permanent tangle-free mode, which affects his turn speed. It certainly has something to do with these parts as I've never had this with original parts. I'm a HUGE Amazon person and order a lot of replacement parts for various items around my house. This is the biggest disappointment of all my orders.
