I believe I had 2 of the 228, if not they were for sure powersweeps none the less. They were great in the beginning, but broke down over time, IME. Loved the sweeping action, but about a year later they just got stuck--no more sweeping. Keep that in mind, I doubt I am the only one this happened to. Went and bought penguins to replace (all the LFS had)--they lost flow after a few months, so now off to maxi jets.
