Since we're talking about whether there's a mass market for domestic robots, that quote supports my point more than yours. A robotic arm consisting of non-novel technology capable of doing nothing more than bagging chips according to a set program costs $35k.

As a householder, I don't need someone to bag chips for me 24/7. Having someone spend an hour cleaning my flat once a week would be quite useful. Unfortunately, the robot arm doesn't have enough moving parts or AI to do that, and even if it could, I could hire someone on a $15 minimum wage to do that on a weekly basis for 44 years for the same price as the robotic arm.
