I know the guys that bought one of the prototype hurricane blo-vacs (its the blue one in some of the website pics, the guy I know is driving it). The two guys I know, own two of the hurricane blowers, one of the prototypes and one of the regular production models. Their employees told me they wouldn't do a clean-up without one. I am lucky enought that these units aren't built very far from me. So last year both Rick and Chris met up with me and let me demo the unit for about an hour. I used it in a very large parking lot and it was in the middle of the fall. That unit could seriously blow some leaves. If you had multiple large parking lots to clear, this blower would make short work of it. Most people who haven't try it will say that it isn't worth it and doesn't look like it would make a big difference. But once you try this unit, you will literally be blown away by it. It's true that it is expensive, but when you have the right jobs, this unit will pay for itself in no time. And the fact that it is also able to be a truck loader, makes it that much more versitile.
