Ex-Pò Concept Vacuum

The Ex-Pò concept vacuum looks rather funny, taking the form factor of a yo-yo albeit in a much larger scale. Since it is relatively small compared to other vacuum cleaners, the Ex-Pò boasts the portability of a hand-toting version while offering the performance of a flexible tube-neck unit. Looks like a pretty handy home appliance to have if you happen to live in cramped conditions. I would like to see this concept materialize though, and it would be even better if it could roll around on its two sides to clean up your home automatically.
