Review on 🧹 RONGJU 20 Pack Replacement Parts for iRobot Roomba i7 i7+ i3 i3+ i4 i4+ i6 i6+ i8 i8+ j7 j7+/Plus E5 E6 E7 Vacuum Cleaner, 2-Pack Rubber Brush Rollers, 6-Pack HEPA Filters, 6-Pack Side Brushes, 6-Pack Vacuum Bags by Allison Smith

This set has some good stuff - Hepa filters, spare bags, even side brushes so I'm giving it two stars. I needed to replace one of my roller brushes so I bought this. The replacement (the front brush closest to the center) worked fine, but the outer brush made grinding noises on the linoleum portion of my floor. I tried a brush from another set; better but still noisy. It looks like the spare brushes are too big which makes them noisy. I put the old one back in and with the replaced front brush, Roomba works again. Next time I will order from another seller and just take roller brushes. If you need brushes, do not buy this product!
