Review on 🧹 Aoteng 2 Set Rubber Brushes, 4 Hepa Filters, 4 Side Brushes: Replacement Parts Pack for iRobot Roomba i7, i7+ E5, E6, E7 Robot Vacuum Cleaner - with 2 Cleaning Tools by Melanie Jones

The rollers are incredibly loud and squeak. Not sure what's going on, but it looks like they don't have the same tolerances as the official Roomba casters. If I take out a roller, the device is quiet. Adding a second really makes you think. I did a thorough cleaning of the device to fix this issue, but the problem persists. I wouldn't buy it again which is a shame because it's great value for money. Everything else in the kit suits me, but the casters have to be ordered separately.
