Trippy, that looks very much like the Chinese vac Eastern Trading used to sell for about £375 on it's own. It's a big bugger, does the job but doesn't have a cyclonic inlet by the looks of it. I sold mine 'cos it was just too big and top heavy for me.
Pretty much getting what you pay for - admittedly the overall package isn't badly priced.
I'm surprised it's branded as a Nilfisk
