This product description states that the yellow side brushes are compatible with the 614. It just isn't! I tried installing the yellow side brush I was given but it kept falling out of its socket. There was no way to turn it the right way around. I had to reinstall my old side brush (which worked, so Roomba isn't the problem). Now I have a few side brushes that I can't use. The filters and other brushes were fine, but since this pack (including the side brushes) is advertised for the 614 and the side brushes don't fit, I'm giving it one star.
