All these numbers sound dramatically inflated. I would like to see just how the readings come out in REAL cleaning conditions.
Like 1Kaday said a 2" hose can only handle so much CFM. I would think 1000 is out if the question and totally unnecessary.
Have you seen the blower blades that a yard service man may use to blow off the side walks?
If a 2" hose is only 12" long you can get a lot of air through them I think.
