According to the chairman of Dyson Japan, their new product — the Dyson DC12 — "costs about three and a half times as much as an average vacuum cleaner, but that was justified by the technology. "
And here at Engadget, we don't need any more justification than that.
Although not robotic (you can't get everything you want!), the DC12 costs around $650 and fits inside a cube measuring 8 inches by 10 inches by 12 inches. Its motor is about half the size and weight of conventional motors but with 50% more power.The DC12 will be available in June, but exclusively in Japan.
