We must be talking about two different things here. A full sized powerbroom, or a powersweep attachment for a trimmer. I don't know much about the full sized deal, but I DO know that the powersweep attachment like what the Stihl is available with is an incredible asset. This is the one that goes on a trimmer unit, and has the drum with the rubber flaps. I happen to clean out quite a few ditches and median areas that covered in gravel from the road plows during the winter. Before, what I'd have to do, was rake the sones downward on each side of the ditches to the bottom. To do this, of course, you're hacking back and forth diagonally with the rake to effectively move the gravel. Then, I would pile the gravel up intp small piles, so I could use the flat shovel to pitch it back up onto the side of the road. HASSLE! Now, I can use the Stihl FS85, and simply move the gravel quickly and effectively UP the ditch and onto the shoulder with one cean stroke - the first time. Simple, and unbelievabally fast. This is done completely clean with NO damage to the turf whatsoever. This unit is also great for moving other materials also. Some materials that are even difficult to move otherwise. (i.e. rotten fruit).
