EGO handheld battery powered leaf blower. You will love this blower. I think it out performs a gass blower because its lighter weight, balanced, no vibration, blows more air faster than most, easy start, variable speeds 250CFM/400CFM/530CFM. I could go on... "CFM" stands for Cubic Feet a Minute. You can adjust the CFM with a dial and the turbo button with your thumb. I can't say enough good things about this blower.
The only negative is the run time if you're doing multiple properties with no way to charge the battery between jobs. If you hold down the turbo the whole time, you will only get 10 minutes run time. Most properties you only blow for about 5 minutes right?
