Hey......just an FYI. I don't know whether that is a "Shop Vac" brand or not(I bought the Craftsman version), but Craftsman carries a filter for their shop vacs(and most likely it would fit a "Shop Vac" brand since we know Sears doesn't manufacture anything and Shop Vac probably builds the Craftsman models too).... that is "specifically designed" for vacuuming ashes, etc. and I use it to clean my fireplace and grills all the time. Doesn't hurt it a bit!!!
