Review on 🔧 Amyehouse Accessory Replacement Kit for iRobot Roomba 600 Series 585 595 614 620 630 650 670 671 680 695 Vacuum Parts - Includes Bristle & Flexible Beater Brushes, 3-Armed Side Brushes, and Aero Vac Filters by Kesha Walker

They don't work with my 690. This batch has an extra flange that doesn't allow it to go in as far as the old brush and I can Don't close the brush frame. It looks like all replacement brushes are like this or the sellers don't show clear pictures of the gray end. If anyone knows who makes a brush with an extra flange, please let me know. A rubber brush seems to work, but they're useless without a brush.
