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 Barbara Robinson

On some bags that are placed in a self-discharge unit, the access door will not close until you fiddle with the bag, but will eventually close. The filters work great but the rollers are missing! Turn on the kit and the vacuum sound sounds like there are stones in the engine! I checked everything, I didn't see anything, for a laugh I put native videos, it no longer rattles. Put it back in and the noise was back. TRIPLE checked they were properly adjusted and they were, so I tried another replacement kit - same, sounded like there were rocks in it. So I checked the dimensions of the ends that align the rollers at the installation site. All driven and non-driven ends have been found to be less than required for proper and proper installation. It could have cost me a bloody expensive vacuum cleaner! I can't return this crap but I can tell you all what to expect when you spend your money on this crap.
