Review on iRobot Authentic Replacement Parts: Roomba 800 & 900 Series Multi-Surface Rubber Brushes - Get a New Set Now! by Julie Bishop

Our Roomba works better than when it's new and 5 years old! My only complaint is that these replacement parts make the car noisier for some reason. We have Roomba on a schedule and it runs at night and it doesn't seem to bother the dogs too much, but if you have to keep Roomba running during the day, good luck keeping them quiet! But they do their job well and don't leave dog hair stains like the originals. I regret not having bought them sooner.
