I've seen that video. Fair play to James, at least he knew it wouldn't work and stopped there. What tech would he have had then? It would have been a re-designed DC05 but heavier... Those tools look like DC05 with a stupid long hose
I'd love to be interested in the new Dyson robot, especially with the digital motors, but at that price, nah, I'll buy a broken one for £40 in 3 years on ebay...
