The Worx WG583 40V Power Share Cordless Blower/Vac/Mulcher has three times the functionality of your everyday leaf blower and twice the performance. This 3-in-1 leaf blower vacuum & mulcher uses two 20V batteries and a high-efficiency brushless motor to drive this enormously useful yard clearing system. Gone are the days of raking all the leaves in the yard into piles, then stuffing those piles into bags, then taking those bags to the curb or a disposal site. This leaf blower mulcher blows all the leaves into piles with much less work than using a rake. Then its one-touch tool-less change system turns this leaf blower into a leaf vacuum so you can suck them all up. Then the leaf mulcher functionality chops them down into 1/12th their original size, so instead of having 12 bags of yard debris, you only have one! It takes a chore that used to take all day and chops it down into a much quicker task. This leaf blower vacuum pumps out 350 CFM on high and 200 CFM on low, at 185 or 116 MPH for an impressive amount
