Not sure if this has been posted here before, but I don't recall seeing it on here so I figured I would post it. Looks like Fantom had a patent for a cyclonic backpack vacuum, which looks a lot like the main body of a Thunder minus the handle and the base. Would've loved to see this exist as this could've taken off well in a commercial environment. I wonder why they never went through with this?
