If you are looking for the closest match to OEM parts for your Roborock, then this is the place for you. The main brush is an upgraded red type, exactly the same as the original brush. The side brushes are indistinguishable from the original, the filters are excellent. The only difference with the filters is that they have an additional mesh pre-filter which the originals didn't have, which probably allows it to filter out more fine dust than the originals, but if you don't need it it's easy to remove with Exact. - Oh, or a razor. I've been using my replacement devices for over a week now and haven't had any issues with errors popping up.
