The good news it that this debris is probably devoid of dust by now with all the blowing going on and some of the cleanest junk in the RV. But I do hate when junk is left around inside walls, ducting and places not visible to the eye. All that junk has gotta weigh say half a pound.
One of these days I'll have to put through a fish line and a poofy duster to clear the ducting. I think I would be happier with this method over a vacuum hose. For now I have to wait for cooler weather. It's too hot now.
