Cyclone chamberThe Cool Products Expo at Stanford University on Wednesday showcased a range of novel products.
Here, the cyclone chamber from a Dyson vacuum cleaner. The chamber swirls around, and the centrifugal force pushes dirt out of the way of the suction.

A small Dyson with a telescopic handle. The company sells this model in Japan. It doesn't have an on-off switch that you step on because Japanese consumers don't like to turn things off with their feet.
