When I bought the vacuum I put the noise suppressor / muffler thingy on it and it does seem to work. I wonder if I can hook a vacuum gauge up to the vacuum cleaner and see if there's any difference in suction. It's a restriction, just like adding the bag is I just don't have a clue how much.
That plus how much harder it works the motor to have these restrictions.
