Review on 🧹 LOVECO Replacement Accessories Bundle for iRobot Roomba 675 677 671 655 645 Robotics - Includes 4 Filters, 4 Side Brushes, 1 Bristle and Flexible Beater Brush, 2 Cleaning Tools by Kristy Campos

Good value for money. Note the tiny screwdriver and screws to replace the three-tooth brush. If you try to use the original screw it will not work as the hole is slightly different. Replacing the brush roll is much easier than trying to remove hair from it.
