Review on 🛠️ iRobot 4636432 Authentic Replacement Parts - Roomba 600 Series Replenishment Kit (1 Bristle Brush, 1 Beater Brush, 1 Spinning Side Brush, 3 AeroVac Filters, and 1 Round Cleaning tool), White by Todd Adams

The large brushroll that comes with the kit doesn't quite fit my Roomba 675. After installing the new brushrolls, the Roomba is incredibly noisy on carpets. I compared it by putting in a larger old brush roll (of the two in the Roomba) and found that one of them made a lot of rattling noise. Inserting this role is also more difficult; Some maneuvering and pressure adjustment is required, unlike the included reel which engages almost instantly. I figured maybe it should wear out over time in the room but I've run it a few times and still the same loud noise on carpets with this new brush roll.
