Almost identical to branded part, but cheaper. The only differences I see are that the strings on the side brushes can flare out a bit, but not much. The color, width, and length of the line appear to be the same. HEPA filter paper seems to be a little more porous, but not by much, allowing larger particles to pass through. The body appears to be identical. I intend to change them frequently and I don't think it will make much of a difference. I'd rather have a small difference in the quality of the filters and be able to change them every time than have a slightly thicker/dense filter that I have to leave out for a few vacuum sessions to save money. Haven't tried rollers yet but expect similar results. I will update this review when they are not done. Very happy with the quality of these parts. Much better than iRobot parts.
