Review on Complete Replacement Parts Kit for iRobot Roomba i7 i7+ i8 i3 i6+ Plus E5 E6 E7 Vacuum - Multi-Surface Brush, HEPA Filters, Edge-Sweeping Brushes, Automatic Dirt Disposal Bags (1+10+10+5 Pack) by Chelsey Smith

I have an i3 which I ordered this for. I'll start with bags. Vacuum bags will fit, but of course the material is a bit thinner than the actual bags that came with Roomba. I'm not sure how well they hold dust. The brushes fit well and do their job, no complaints here. The air filter fits, but given the thin vacuum cleaner bags, I have my doubts about the effectiveness of the filters. Straight up rolls don't fit and don't work. I put them in, turned on the vacuum and the noise was awful. It seemed like the vacuum was about to break. I double checked that the roles are installed correctly and tried again. Another horrible sound. I then attempted to replace one of the rollers with the original factory roller. The dark green reel that comes with the kit works great. Light green is complete nonsense. I left the factory light green roller with the new dark green one and it works great, nice and quiet. With two new ones, it looks like your Roomba could explode any second. While it's nice to get the number of items that come with this package, I'd skip this one and look for a higher quality one. If I could I would send this one back.
