I like my electric blower, light, easy to use, very powerful. Always check to see how much power you have, before purchase. Mine is older, but blew 125mph when I got it. does a nice job.
I got it for dust and small things, sawdust, wood chips, that seem to accumulate where the broom won’t touch them. Works very well for that.
I have center aisle, doors open at both ends, prevailing wind from the south west 98% of the time. So it works well to start at the west end, blow everything on out the east doors. I NEVER have any animals inside when blowing.
I ALWAYS wear a handkerchief scarf or paper mask over mouth and nose, goggles over my eyes and high decibel ear plugs when using the blower or shop vac in the barn. Enclosed area throws the noise back at you, making it LOTS worse for ear damage. I get the ear plugs at a local Industrial Supply by the carton, 100 pairs inside. They have a higher protection rating than the earmuff protection devices, which just KILL my jawbone no matter how I put them on. Ear plugs are easier to use, cheaper, better protection.
I only use the shop vac for cobwebs. For some reason, they have to be swept or wiped off the walls, to get them down.
Blower is good for accumulated dust, not cobwebs. We got a blower at work warehouse, so I learned a lot about how useful they were, limitations on cobwebs. We had a CLEAN, nice looking warehouse because the blower did a super job on the racking’s dust. Like a barn, the warehouse was open for driving in and out with forktrucks, so dust blew in to create dirt. Stock was all outside equipment, so dust didn’t bother it, just looked bad to visiting officials. I wouldn’t want to be hauling a gas powered machine around for cleaning. The long cord for mine is pretty easy to manage. It also blows out the horse trailer very well after cleaning those stalls, gets the last dusty bits out before putting trailer back away.
