I dropped it twice last Saturday and neither time did it go down the hose, but that really is a thing. "Finding" it is not so bad, you know where it is, when it's down the hose. You just have to crawl under the outfeed table an disconnect the hose. This time, I heard it the metal bottom, so I knew it wasn't in the hose.
The dust collection is pretty decent, because of the trough thing, so digging in the dust isn't so bad. Our old PowerMatics would get neglected once in a while and the dust would get so deep inside that it would fall out on the floor, when the door was opened. I never dropped the nut or flange washer in those though.
