4 Sets Replacement Rubber Roller Brushes Compatible for iRobot Roomba E & I & J Series, Replacement Parts Accessory for J7 J7+ i7 i7+ i3 i4 i6 i6+ i8 i8+Plus E5 E6 E7 Vacuum Cleaner

Ive bought numerous off-brand brushes for my i7 over the years. This particular brand does not fit well, and causes an clean your brushes error within a few minutes. Changing to a different set of brushes made by another manufacturer worked perfectly. I cant recommend these. Fit and finish were terrible.

I’ve been a long time user of buying generic brands for my Roombas but for some odd reason they could never get the rollers right therefore causing loud obnoxious noises whenever the Roomba starts cleaning. This particular brand alone actually works perfectly fine. No loud noises, bags fit, filter fits and side brush works.

The filters do not fit, they have a ridge on them that prevents them from fitting or being snapped in. I was disappointed in this item.

Perfect replacement, great value for the money. Will continue to re-purchase. Highly recommend.
