We use a Stihl gas backpack blower at work to blow out the hanger, and if it isn't bolted down it will be blown away. The mats by the door are a very heavy rubber mat, and it will pick them up. Heck you can roll the tables around with it.
I honestly prefer electric. Its just the kind I have always used. But I know people who love gas also. I have a Greenworks G-MAX 40V 185MPH DigiPro Leaf Blower/Vac which is electric.
