We just spotted for preorder on Toolnut a 20V outdoor cordless brushless blower from DeWALT.  Unlike the Milwaukee 18v blower that puts out a paltry 100cfm at 100 mph, the new DeWALT DCB720P1 puts out 400 CFM at 90mph.  Basically you can use the DCBL720P1 for blowing just about anything.  This tool can do some serious job site cleanup.

The included 5.0 Ah battery gives you up to 18 minutes of runtime. The blower weighs in at 7 lbs and has a variable speed trigger that you can lock to dial in the right speed. Those of you that were interested 40V DeWALT blower now have a 20V alternative that produces some serious power.  Best of all you can use your existing 20V tool batteries.
