Oh wow you're right - it IS a dutch tech. Although I think the Rowenta is considerably older. Another case of Mr. Oreck using someone elses design me thinks.
I really don't think that Goblin and Panasonic US are related tbh. Goblin are a british company, and as far as I am aware, Panasonic always had a fairly good reputation in the states. Goblin were quite well known for being more of a budget brand in the UK and not particularly reliable. The commander upright pictured above (and also available in a hard bag model) was pretty much designed for rivalry with the Hoover Turbopower, as this became Britain's best selling vacuum in the 1980's. They were a little behind the times though. By the time the Commander uprights came out in the late 80's, Vacuums with on-board tools were becoming increasingly more popular and it wasn't long before Goblin replaced the Commander with the Laser (which seemed to be absolutely everywhere when I was a kid, but you don't see many of them anymore)
