This item, for it's price, was a big disappointment. For me the issue was not finding a suitable trashcan. (Found one at my local home improvement warehouse). My issue was the total lack of design consideration as far as vacuum leaks were concerned.  The basic principal of this thing, I guess, was just to drop this thing on a trashcan stick two hoses IN the holes on the lid and just hope all the air leaks would not drop the efficiency of the system to the point that it would still move some dust.
