Shop Vac here too. Make sure you use a hepa filter or every time the wifey dusts you're going to hear about it. I wonder when someone will chime in and warn me about a vacuum fire? Should be soon...
You should be careful with those Shop vacs, Because if you're a numb nut and suck up a glowing red ember BECAUSE YOUR STOVE IS STILL RUNNING.......Sorry I had to!
Rigid shop vac w/ hepa filter. I buy 'em @ the box store on tax free day for like $20ish. At that price I could care less if it get's torched!
