Replacement Parts Fit for iRobot Roomba s9 (9150) s9+ s9 Plus (9550) s Series Wi-Fi Connected Robot Vacuum Kits (2 Rubber Brushes, 4 Filters, 6 Side Brushes)

I do have the self-empting Roomba S9. I dont know if they were just printed wrong, or maybe I got a bad batch. But the brushes that came in dont quite fit right because they rub against each other and make a loud obnoxious noise and also on hard floors make the Roomba jump and bounce over and over and over and over.

The new parts seem to make my S9 louder. The flaps that have contact with the floor on the dark green replacement cylindrical rollers are wider than the originals. I hope this new, louder vacuuming doesnt burn out the motor. The filter and side brushes fit and work fine.

These Theresa Hay replacement parts are a perfect fit for the iRobot Roomba s9 (9150) s9+ s9 Plus (9550) s Series Wi-Fi Connected Robot Vacuum Kits. The rubber brushes are durable and the filters are easy to install. The side brushes are also a perfect fit and work great. I highly recommend these replacement parts!

They are a lot cheaper than the manufacturers so it works out dollar for dollar. But you have to change them out more often so a little more maintenance on the machine..

I purchased this mainly to replace the two green rollers. Just as others have listed in their review, the roller start to rip apart and they are very loud! We only used the vacuum maybe 3 times before I noticed them ripping at the ends and the tread on them smoothing out completely

The lime green brush quickly falls apart.

The rollers and brushes wear out immediately and need to be replaced. It’s a better investment to buy genuine IRobot replacement parts.

Side brushes continuously break within the first day of use

They seem to work, but they are too big. They make very loud flapping nose as the brushes bang against the body. Very annoying, I wont purchase again.

Parts fit well and works as expected
