I'm excited to see that this technology at least exists. Dyson has been misleading the public for almost 20 years now touting their design never looses suction, when in fact it does since the pre-motor filter clogs fairly easily. Now that issue is out of the equation, and they have a product worth selling. My one concern are those flexible cyclones. If any sort of moisture gets inside them, all the dust will turn to mud, preventing any oscillation and clogging the entire system.
