Overall, these brushes seem to have a good grip, but I have three observations. Tool, so end cap must be removed from brush to clean. On two of the three brushes, the end cap came off with minimal effort. The one I installed (of course) took a little more effort. After removing the round nozzle sits perfectly. Second, the bristles feel softer than standard Roomba brushes. I'm not sure if this is a problem or not. Finally, these brushes don't seem to work as well with the Aerovac trash can as other brushes I've used. These brushes tend to have more lint, requiring the brushes to be cleaned almost every time they are used. I wonder if it's because of the softer bristles. Update: 02/21/2015 On the brush deck, dirt balls have accumulated between the shield and gear side. This can cause a "click" as the brushes stick. The gap in the brush was too large, leaving a gap between the screen and the brush wall. Dirt could get in through this gap. I solved this problem by adding a thin washer behind the yellow connector. I had to experiment to get the correct shim thickness, but this eliminated the play in the brush. Dirt no longer accumulates.
