Let's look at the economics. In the US or Western Europe, a human worker would cost you about $12-$15 per hour (depending on the actual city and whether they're paying their taxes). You're looking at roughly 4 hours of work per 100 square meters (the average housing size[1]) per week to get the listed activities done, plus some general cleaning. So let's call it $60 per week or $3,000 per year. If we estimate the average useful lifetime of such a robot at 5 years, they'd need to cost less than $15k (unadjusted for inflation) to make sense. This does not take into account that the house owner also would be paying for a small portion of the societal cost of this additional unemployed houseworker. If we assume that there are roughly 1 maid per 500 citizens[2] and that each unemployed worker costs roughly $20,000 to the State per year[3] then our back-of-the-napkin math says the robot worker is generating a socialized cost of $400 per year per household member (2.17 members on average). So... we need a ~$14,132 fully-automatic, solar-charging bot before your dream can break even.
