Looks like Milwaukee has a new compact 12V vac out.  It delivers 34 CFM and runs up to 29 minutes on a XC 4.0 battery.  It’s compact at only 2.2 lbs and 17.5″.  It has the Milwaukee 5 year warranty.  Basically it looks like a Dust Buster with a clear viewing window.   Check out more via Milwaukee Tool.
