Hey everyone, I'm wondering if anyone knows anything about these canister models, I've seen them mentioned but finding anything about how good they are is a bit more difficult. Has anyone heard of the patriot vacuum? Apparently it's a very good expensive vacuum, found some youtube videos showing it, motor has a good sound, I'm guessing it's a two stage motor. I also read that this vacuum is related to the tristar vacuums. What about the nss m1, I know it's nick named the pig, I know it's a commercial canister, quite expensive, is it worth the price? And finally, the Windsor treck vac, there are two models of that, I'm assuming the Treck Vac 3 is the better of the two. Just was wondering if these vacuums would be worth considering for the collection.
