Cyclone Rake. Great design, great company. I've had mine for 10 years now. The only issue has been a bent side frame rail (backed into a tree - don't do that) which was replaced quickly at a reasonable cost. This year I did a second repair on the unit - patched an inner tube that developed a leak.
The criticisms you will see about the CR is that it has a cloth bag. Mine is in great shape after 10 years and that allows the whole unit (minus the engine/blower) to be folded up and hung on the wall. It has replaceable wear patches on the inside, but I haven't had to replace any yet. Also, it is a solid mount to the tractor/mower instead of a trailer, which means you have to be careful about it swinging out when you turn.
On the plus side, the solid mount makes it easy to back into tight spots and allows the vacuum hose to be shorter. No supports are required to keep it from dragging like the trailer models.
I have the long pickup tube and it works well for cleaning up flower beds and places you can't mow. It has the power to pick up small rocks so you have to be careful, but I've picked up a lot of rocks and few aluminum cans, etc with no damage to the unit. I got the optional hardened liner for the blower because I pick up millions of acorns.
I have the Commercial Pro model and I would recommend getting a unit with at least an 8" vacuum tube. That pretty much eliminates clogs.
I have a lot of trees and compost the leaves every year.
