I came across another usual (and rather massive) beast this time. This is an Advance CarpetTwin 16. This as the name implies has a 16" sweep and was mostly intended to be a hallway vac or for use in wide areas. I have to say this is probably the heaviest duty vacuum I've ever seen...this has build quality that would make my other commercial work horse,a Windsor Versamatic VS 14, or even a Kirby, look flimsy. I haven't weighed it yet, but I'm guessing it tips the scales at at least 40lbs. The entire base and handle is make out of very heavy gauge metal. This also is not a streamlined design so there is a lot of "wasted space" inside of it. The bag housing is made of plastic, but this is a very heavy plastic, I can't imagine what you would have to do to it to break it.
