Review on Roomba s Series Vacuum Cleaner s9 (9150) s9+ s9 Plus (9550) Replacement Parts Kit - Replenishment Set, Including 4 Filters, 6 Corner Brushes, 1 Set of Multi-Surface Rubber Brushes, and 2 Dust Bags by Amanda Bonner

Of those who don't write many reviews, please take my advice. All sweeping arms fell apart on first use. The wheels are a good 1/2 inch longer and the plastic connector doesn't fit either. Filters and bags are fine, but understand that's about all that's useful from this pack. I always try to find the best value for money but unfortunately this was not the case. I only rated 1 star because there is something to add.
