Nothing destroys a shop-vac like fiberglass, this Fein shop vac eats it up. I leave it running for 20-30 minutes at a time rather than cycling on and off because it's so quit.....great investment.
The down side it is hard to find vacuum hose that will fit power tool dust exractor couplings, Mikita compound miter saw and Bosch portable table saw.
The vac is the perfect shop vac and the perfect attachment for your sander.
Works exceptionally well,, above all other vacuums.........
