Dan P.,
Looking at your carpet you will be fine with the green roller. You will notice the carpets will get softer with repeated use. I have several rooms of berber the same color and shampoo with the FloorPro and Kirby lavender suds. The stiffer bristles beat that soap residue out a lot better.
Floor-a-Matic,
That is what I call double helix. Can you post some up close pics of you Tristar CS nozzle lid on and lid off? I have never seen one up close and personal. I like the idea of the metal top cover.
