Review on Mochenli Replacement Parts Kit for iRobot Roomba i7 i7+ i6+ i8 i3+/Plus E5 E6 E7 Robot Vacuum Cleaner - Includes Rubber Roller, Filters, Side Brushes, Dust Dirt Disposal Bags, Replenishment 25-Pack by Andrea Olson

I almost couldn't resist buying because of the negative post about videos. Of course, as soon as they arrived, I compared them to the original commercials. No visual difference! All parts are vacuum compatible without any problems. The noise may have increased a bit just because the original rollers were so worn they almost didn't make contact with the ground. So if you replace them with new ones, the noise will of course increase a bit, but I suspect the time after wear will also decrease, but this will probably also be the case with the manufacturer's spares. I highly recommend purchasing these parts.
