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

They work.

As you can see, the replacement filters (lower in the photo) are bigger than the original filters (upper in the photo). They do NOT fit in the j7+ Roomba combo. Do NOT buy if you have a j7+ Roomba Combo!!

Parts fit perfectly!!

Air filter in the front is original Roomba J7+. Air filter in the back is replacement from this kit and too big to fit into the vacuum.

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.

Don’t fit the vacuum

Can’t tell the difference between this and OEM. I have ceramic tile floors mostly.

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

Easy to Install and value for money
