Yes the "snout"of the "pig" is for nuts and bolts,coins and such.Used mine to clean up a remodling job in freinds(worked far better than his Craftsman shop vac) basement-was amazing what the "pig" digested-hence its name-conduit box knockouts,scraps of wire,nails and cable staples-all of these went thru that huge fan-and the blades on it are close to quarter in thick-I recovered from the dump bag(used the dump bag on this becuase of the quantity of debris)bent nails and box slugs that went thru that fan-and not a ding on the fan!And another thing the fan housing is steel lined-has a steel liner-so the housing won't get punctured by such things.Imagine these things going thru that Kirby fan!Probably the Kirby fan would shatter from the first nail or staple.Kirby vacuums when used with the hose should have a scrap trap like the pig.And note from the picture how EASY it would be to remove the NSS fan for replacement-the big "acorn" nut holding the fan to the motor shaft-after that its easy to get the motor apart.
