Brian, you just reminded me that I did have a vacuum when in Korea...had completely forgotten about it. It was some kind of stick vac, similar to one of those 1980's Hoover models (I forget the name of these vacs), and it didn't have much more power than a Dustbuster. No wonder I forgot about it and left it there.
As for Chinese vacs, if you go to the "Vacuum Collections" tab on the home page, you can see my entire collection, including the two vacuums I have in China (they're still there). They closely resemble the Electrolux Oxygen in shape and style, and, as far as I know, aren't available outside of China.
