I hooked up the Black and Decker Sucker upper to the exahust pipe today. Funny stuff! Who doesn't loved that huge cloud of dust and smut. I had a nice fat length of corrugated black plastic pipe lying around so I just taped it to the leaf vac and then to the vent which allowed the whole setup to be 15ft from the house and the exit hole facing away. A lovely cloud with the wind in the right direction...
