kinda like the Converto-vac, no?

No haven't seen or used one of those-but it looks like from the items and debris it could pick up-would be good for cleaning out auditoriums and movie theaters.I would think with those large items they talk about in the description it would fill up fast.

lamb suction motor and a wide but not very tall bag mouth. It picks up good, but the bag is small and does not hold very much!
