Welcome to this forum!
Per Dyson, on July 2005, their robot version was cancelled. Here is the Email they sent to one of our forum members:
Thank you for your email dated 17th July 2005.
Dyson has developed an autonomous vacuum cleaner that is powerful enough to clean efficiently and is sufficiently intelligent to take a methodical path around the room. However, given current technologies, it is impossible to achieve high pick-up performance without pushing the cost of the machine above acceptable levels. Therefore Dyson will not be releasing this model at the present time.
Producing something that bounced aimlessly off the furniture and picked up very little dust would have been easy, but James Dyson insisted the Dyson DC06 robot should not only clean properly but should also guide itself more logically than a human would.
Should you have any further queries please do not hesitate to contact our Helpline on 08705 275 104. The Helpline is open 8.00am to 8.00pm, seven days a week.

Here is the original thread were it came from :DYSON TALKS
It's sad that Dyson is not moving forward with this, there is much future in consumer robotics and so far iRobot is the king in this area.
