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

After I put them in, I could tell they made the roomba strain. They seemed to work fine on the tile but the carpet is a different story. And because it seems to be harder for the roomba to move them, the battery life is shorter so its cleaning sessions are shorter. I guess Ill have to go back to the more expensive ones.

I keep getting brush errors and it will not clean with the new brushes

Good

These dont seem to operate as well as the originals and are much louder.
