A customer talked me into renting a Little Wonder leaf vac today (his expense) to see how it would do sucking up acorns, leaves, etc... I had been curious as to how they work. Overall, I'd give the thing a C +...maybe a B -. What I did like...the way it picked up stuff off of driveways and sidewalks. What I didnt like....having to stop the engine, take the bag off, empty it, put it back on and resume. Just not as fast as blowing and hauling in tarps. Also it didnt really pick the acorns all that well. All in all, I dont see me ever buying/using one.
