Review on LOVECO 4 Set Replacement Rubber Brushes for iRobot Roomba E Series E5 E6, i Series i7 i7+ i8 i8+ i3 i3+ i4 i4+ i6 i6 Plus Robotics - Multi-Surface Rubber Brush Set by Lisa Lord

Roller Shafts are scrapping. I replaced two sets of rollers six weeks apart. Shafts that should be pushed slip out of the roller or break, preventing the roller from rotating, causing Roomba to malfunction. If possible, avoid them. I am going back to Roomba parts as you spend more money on these imitations as the lifespan is about 10% of the OEM parts.
