This is an almost perfect set of replacement parts for my Roomba 980/985 (Costco version of the same). There are a few reels that will fit (hex point) and a few that will not (square point). The only problem is that the casters are slightly larger than the original Roomba casters. It hasn't affected Roomba's ability to clean yet, but I've only tried it once. The rotating brush change works perfectly, as does the filter.
