Am I missing something? Anyone with a turbuflotor chime in please. You know how the clear part of the collection cup just kinda fits into the colar with nothing to really secure it permently. Is there some trick to removing the collection cup for cleaning? Everytime I try to take the cup off the clear part just spins in the collar and I can't get it off. This probably sounds stupid but I don't get it. I would think this thing would be better enginered for $200
