Bests & Worsts Reviews from Amazon

***Updated with picture comparing the ripped up crap rollers vs. the iRobot original ones that I had to order after these failed to work. You can clearly see the design difference at the end of the roller. They are slightly longer than the originals, and the edges catch in the roller cage and start tearing to the point where they will no longer turn. After just 2 days of use! These roller replacements rendered my Roomba completely useless on carpet. It's ok on tile and hardwood, but as soon as it hits carpet, it gets hung up and alerts that it has an error 2, and that I should clean the rollers. The roller housing is 100% spotless, since I did a total deep clean before replacing the rollers, but they still can't turn for some reason. Also, the edges of the rollers became worn and jagged after 2 days of use, despite no hair or debris being trapped around them. Total junk.
