Replacement Parts for iRobot Roomba i3 i3+ i4 i4+ i7 i7+ i8+ i6 i6+ Plus E5 E6 Vacuum Cleaner,2 Rubber Brushes & 8 HEPA Filters & 10 Edge-Sweeping Side Brushes

I was skeptical at first because they felt kinda cheap, Pretty thin plastic. But these exceeded expectation and definitely get the job done !

I've had my J7 for about a year now and recently started using the non-brand rollers and replacement parts. These guys here fit just fine and while they last about 50-75% life length as the manufacturer ones do, longer if you take care of them, they get the job done and do a good job.I have a lot of cats and I shed rather a lot myself with long hair and outside of the traditional 'cleaning the brushes of my own hair' upkeep I had to do with the originals, I see no real difference outside of noise.The first 2-3 times after switching the rollers (to this brand) it can be rather noisy until the rubber grips are worn down some (but they do their best cleaning on carpet while new.) After that, it's the same ol' thing for half the price or less.

As some other reviews already state, these aren't a perfect fit for my Roomba, as one of the little pegs is too long. Still fairly easy to install and use. For the price, I can't complain.

This replacement part for the Roomba i3 is as good as the original and works great. At least once a year or maybe even twice a year it's a good idea to change out the replacement parts and Amazon is an affordable place to purchase the parts. A+

Durable and well worth your money..

The pegs did not fit the slots in the roomba. Had to force in. Then roomba would not run because the rollers jammed. Cheap knock off.

Replacement of parts was nice and easy. Parts work great.

I've never seen an actual brush break in half, but I now have experience two roller brushes break in half from this aftermarket part. They literally break in half. On top of that, the actual contact surfaces break down rapidly after use. Within a couple of months, they were almost clear and smooth rollers with the brush component worn away.That being said, the price is drastically lower than OEM parts. They fit perfectly, and get the job done until they wear out. The set of two full replacements lasted me from May to November, so about 3 months per purchase/set.I wish they lasted longer, but I feel these are still more affordable than the OEM units. Your mileage may vary. My house is hard floors and short carpet. I feel that more plush carpet would wear them down much faster.
