Replacement Parts for iRobot Roomba s9, (9150) s9+ s9 plus (9550) S-Series Robot Vacuum Cleaner 24 Pack, (2 Pair of Multi-Surface Rubber Brushes, 6 Filters, 6 Side Brushes, 6 Dust Bags and 2 Tools)

They fit like a charm. I highly recommend.

Product is a high-quality product that matches the original parts and fits.

I appreciate the compatibility with my roomba s9. The parts from the roomba store are way more expensive for less product. We use ours every day and these have held up nicely.

These roller attachments seem to be a little bit larger than though name brand iRobot rollers. When you put them in and you start the Roomba it makes a horrible noise. Looks like it rubs against the floor. You just can't use them. They just make too much noise.

Most of the replacement parts work fine but I have the j9+ and the bags don't work. For a few seconds it recognizes that there is a bag then it thinks there isn't a bag in place. I tried it with several and they all do the same. I guess I need to go back to the brand name bags
