It would have to be absolutely required for your life at that price. The car is the closest to this given that price point and many people forgo that, so I can't think of anything that you would absolutely need a robot for.
There are a few good applications in healthcare that can (and do!) justify the expense of current robots. Still, it's often easier to target concentrations of people where you can cost-share a robot (eg. nursing homes) rather than operating in individual homes. But problems in nursing homes abound too: abysmal connectivity (no WiFi!), antiquated enterprise sales; excessive regulatory costs (FDA), etc.
Maybe costs will come down... but most "good" applications require manipulation, which makes a "general purpose" robot much more expensive than an autonomous car's sensor suites.
