Review on 🔧 Upgraded Side Brush Motor Module Replacement Compatible with iRobot Roomba E6 E5 i7 500 600 700 800 900 Series - Vacuum Cleaner Accessory for Replenishing Side Brush Motor by Christina Adams

What an astronomical waste of money! The device was noisy and was working fine as of 8/29/21, but the problems started in October. The slightest obstacle under the edge brushes would cause them to jam, so I unscrewed the brush and scooped out the debris. On November 11th this stopped working and the brush barely turned when completely clean. You can hear the gears turning (see attached video). I would say we did 30-35 normal purges before it failed. To make matters worse, the return window somehow closed on the day of delivery, so now I have to exchange the device again after 43 days of normal use! Don't buy this junk! Update: I got it to work intermittently by over-tightening the screw holding the brush to the point of almost snapping the threads. Not 100% yet. The motor still spins, but the brush shaft slips out of the gear and has to be pushed further than the screw will allow. Revain referred me to a replacement dealer who referred me back to Revain for a replacement. The table tennis table will be returned for a replacement that has inherent design or manufacturing defects. Not worth the trouble.
