Superpower blowers are of VERY limited use on 99% of the fall leaf cleanups that I do.

On golf courses, municipal parks, or estates with large open grounds and even larger wooded areas that you can blow the leaves into, sure.
One of the videos shows a guy blowing leaves off a large commercial parking lot. Where to ? The store next door? You still gotta pick 'em up, and blowing them a mile away doesn't help, IMO.
For most of us, we can't blow the leaves off the customers property and on to their neighbors. We need pinpoint and powerful blower capacity to get them out of the beds and away from the house. Once they are away from the house, you could use a superpower blower I guess, but not for 10K
