Review on 🔧 Amyehouse 2-Pack Tangle-Free Debris Extractor Set Replacement Parts for iRobot Roomba 800 & 900 Series 805, 860, 870, 871, 880, 890, 960, 980 by Kia Adams

Price was good but I have strayed from brands before and if they are not up to size in diameter and width then there are problems. The rubber on the roller was about 1/4 inch smaller than the original, leaving more room and not capping the ends like the original. The rubber diameter and ribs were only slightly smaller than the original. This presents a problem as there is more clearance between the rollers where dirt collects. If the ribs have a lot of clearance, they won't compress well enough to trap debris in the bin. Material wrapped around the rollers, I will report Update 03/16/2019 I have tested several sets on plush carpet, area rugs and tiles, they have worked well but the difference in roller size negatively impacts performance. I bought my more expensive ones from iRobot and they work much better, it's a noticeable difference especially if you have dogs or cats.
