Dyson is about invention.
We get frustrated when technology lets us down. As engineers, we see how we could improve it. We try lots of ideas - most of which are wrong. That's good. Wrong ideas and new mistakes are incredibly valuable to us. They spark unthought-of possibilities and answers. That's how new technology comes about.
Root cyclone™ technology
Dyson cyclone technology doesn't lose suction because it doesn't rely on a bag or filters. Dirt has no chance.
Airblade™ technology
It doesn't look like one. It doesn't work like one either. Meet the only hand dryer that works properly.
