iRobot Authentic Parts-Roomba s Series Replacement Dual Multi-Surface Rubber Brushes 4646490, Robot Vaccum Accessory, Green

Perfect fit and long lasting. Quiet in the machine too. Tried various off brands and they were very noisy and made the roomba bounce around a lot. These ones had a lower profile so they wernt so noisy and didn't jump my vacuum around like it was in a dancing in a mosh pit. The low profile.i would have thought ment it would wear out faster but it was the opposite, because it wasn't scraping so hard it actually lasted longer.

These rollers are the original manufacturer part and are reasonably durable and fit every time. The won't last forever, but you already know that if you're shopping for replacement rollers. I use my Roomba every week or two and have a dog that sheds like crazy. Unfortunately I need to clean the rollers after every use or they won't last very long. But cleaning the rollers is better than vacuuming the whole floor! Replacing them is easy and they do what they are supposed to do.

Não compre escovas de borracha não originais para o seu robô da iRobot achando que está fazendo um bom negócio. Elas até funcionam no começo, mas estragam muito rápido. Em menos de duas semanas já podem entortar, rasgar ou ficar frouxas, e aí o robô começa a limpar pior. Ele faz mais barulho, pega menos sujeira e você percebe que não está funcionando como antes. No final, você acaba tendo que comprar a escova original mesmo. A peça autêntica dura muito mais e mantém a limpeza eficiente por mais tempo. Ou seja, o barato sai caro: você paga duas vezes e ainda passa nervoso. Melhor investir na original desde o começo.

Depends on how much dirt you had in your house, how much rugs shed, etc.

Fits the product well with no challenge replacing the parts
