Review on 🧹 Aoteng 2 Set Rubber Brushes, 4 Hepa Filters, 4 Side Brushes: Replacement Parts Pack for iRobot Roomba i7, i7+ E5, E6, E7 Robot Vacuum Cleaner - with 2 Cleaning Tools by Danielle Rogers

Parts look like originals but rollers generate high vibration and noise. This problem has been reported in several comments, so it may be more pronounced depending on the model. I have E7. The reels have an end play of approximately 0.125 inches. I added a spacer but it wasn't the source of the noise. I then noticed that if I click on the lighter green roller while spinning (device turned upside down for testing), I can eliminate the noise. The old and new rollers looked the same on the outside and were measured the same, but I found the difference by squeezing them between my fingers. The new one felt weak. I disassembled and found a thin black foam cylinder around the new axle and a thicker and harder white foam cylinder. on the original. The vibration seems to be caused by the roller guard hitting the smaller black foam axle cover and brush housing (see pictures showing the internal gap between the black foam and roller guard). I proved this hypothesis by replacing the old axle and foam rubber with the new roller skin and the problem is solved. Now I'm worried about other parts; Filter, wheel and triple brushes are junk too. You get what you pay for. I'll use my Franconia solution first, but next time I'll buy an OEM for about 20 euros more. It's not worth my time fixing these unnecessary parts, or worse, risking them damaging my sweeper. Update - My original roller's blades have worn down in places and I now pick up a lot more dirt with each cleaning. So if you're wondering if the new parts will help - yes! The rollers are subject to annual replacement, the filter and the triple brush more often according to the user manual. See images for foam comparison (black=new, white=OEM), foam gap (gap between black foam and shroud), and axial vs. lateral clearance comparison. between new and original videos.
