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

Fits perfectly! BEFORE I bought this brand/set (genuine iRobot brand), I chose quantity over quality. I found a few unbranded reels that looked like they would be a worthy replacement and I would get more than a pair and I was very disappointed. I learned the lesson pretty quickly to only buy parts made by the manufacturer for the real product. These wheels are perfect for my Robbie O Roomba. I'll buy again when the time comes.
