To this day, the Roomba remains the one successful mainstream home robotic. It was a feat iRobot achieved after a decade or so of throwing concepts against the wall, ultimately achieving success through a combination of outward-facing simplicity and under-the-hood sophistication.

That other robots haven’t achieved those heights isn’t for lack of trying. The field has been littered with promising, high-profile failures. Notable recent additions to the dust bin of social home robotics history include Anki and Jibo. Both projects had interest and funding, but were ultimately unable to sustain.
