@Rich... Though about that too... The reason I thought of iRobot is because they seem to be at the end of the development of floor vacuums... I mean in the sense of how much different or better can you get it to clean?.... It cleans very well now so I would think that the next logical direction would be to focus on making it smarter, pc/internet connected, voice controlled, etc.... I am sure their software developers could do this, but as the saying goes "why reinvent the wheel" just use a ready made one... In this case lic ez robot...
