This kit fits my Roomba and works. But it has a few notable downsides. The screws that come with the rotating brush are Phillips head only. The originals are optional straight/across so I can replace them with a butter knife instead of looking around the garage for a small cross. Rotary cylinders will fit, but require a little extra work to fit into the slots. The filter is also a bit smaller, but still fits in the camera. Everything is a little different, but still fits. Doesn't seem to affect cleaning performance. Overall this set works and comes with an extra cleaning brush and stiff comb for the other parts. Something most kits don't have.
