THE MOST POWERFUL ELECTRIC BLOWER IN THE MARKET. The 800 CFM - 12 AMP Electric TURBINE Blower is, quite simply, the most powerful electric blower in the marketplace. Other 800 CFM (Cubic Feet per Minute) blowers don't put out wind power at 135 MPH. They just don't. Physics shouldn't allow it, but our engineers found a workaround. And even though you're going to want to blow at that speed all the time, you can actually dial it down if you need to, using the variable speed control. (Some types of surfaces are easier to clear off at lower speeds.) Believe it or not, all that power can be controlled with 1 hand. The whole unit is only 6-1/2 lbs., and that amazing TURBINE tech creates a wind tunnel that is easy to point-but you don't want to be on the business end of it. The handy-dandy cord retainer keeps extension cords from pulling apart, even on snags. And you don't need any tools to put it together. C'mon, let's go clear your lawn.
