Having a robot bake A cake and then wash the dishes. Not sensical to build a custom bot.
Laundry and washing dishes is not just “putting things in a spot”. Perhaps you don’t fold your clothes or separate your clothes or scrub dishes but many people do. Even loading the dish washer is fairly annoying when it’s a large crowd. Cooking is of course a huge one.
The question is really just how much would you pay for a 24/7 live in maid that can cook, clean, repair, etc. with a real human you’re paying them for availability. With a remote operated robot you’re paying for just the labor hours and none of the downtime.
It seems kind of fucked up but I do think the economics could work. People do have servants today. I tend to imagine such a service would be cheaper than a servant even at $20k up front cost. I do agree the bipedal legs seem unlikely be cost effective.
If it's a robot that needs to be able to work in any room, including navigating stairs, I'd think being bipedal is the simplest way to achieve it. Maybe make it tripedal to make walking/balancing easier.
