I've been totally happy with the Cyclone rake since I bought it in 1990.
The one shown is the "Classic" model. It really works well on the leaves which are already falling in my area. As far as grass clippings, if I didn't have this machine, I simply wouldn't bag at all.
I especially like the fact that it connects to the mower at 2 places (no swiveling) and has pneumatic casters so it backs-up easily (not like a trailer).
