Review on 24 Pack Replacement Parts for iRobot Roomba s9 (9150) s9+ s9 Plus (9550) Wi-Fi Connected Robot Vacuum Cleaner - Extolife (8 Filters + 8 Side Brushes+ 8 Bags) by Kristina Davis

I just received this kit and installed the rubber brushes in my Roomba S9+ and it was very noisy compared to the original brushes it replaced. I made sure the brushes were installed correctly and that was it. It's so noisy when walking on a carpet that I'm afraid it won't fit and might damage the robot. I think you get what you pay for.
