I would like to mention that the addition of the cooling fan did have one downside. And that is, it made the 16.5 even louder yet. Yes, this addition of another hole serves as an exit for sound more easily leaving the machine. It cannot be helped, unless this problem is adressed in some other way, with perhaps lining the machine with some sound deadening materials,
The loud vacuum sound has went from a horrid muffled roar, to almost a gun-shot startling experience when hitting that Vacuum Motor Switch.
Other ideas that come to mind, is a stand that somehow encases the machine, but of course the easiest, is a pair of headphones tolisten to some tunes while you clean.
I did a two hour run this morning in fact. Regardless of the loud sound, I have no regrets buying th 16.5.
