People already buy robot vacuums to do a decent job of vacuuming a decent amount of their floors. It is a $4.48 billion industry. Roombas don't look like people. They don't even look like pets or animals. They look like big hockey pucks. I have one and I have it run as soon as I leave for work because I don't want to interact with it, I want to have clean floors. If there was a robot that could fold clothes, load and unload the dishwasher, dust, and general purpose clean, I would have it run when I wasn't home too and would prefer if it folded up into a little box in the corner when I was home.
Roomba uses AI in some of their models, but people aren't trying to have a relationship with them. Because it is AI to serve a utilitarian purpose that does not involve imitating human behavior. People have relationships with chatbots because they are specifically imitating human behavior. Putting googly eyes on your Roomba isn’t the same as falling in love with a chatbot.
Cars are very very publicly visible, so they are used to project some sort of image to others; like the clothes people wear. Most people don't wear clothes or drive cars for purely utilitarian purposes. Often people will buy clothes or cars that look utilitarian to project an image about themselves. People buy furniture and decorate their homes to project an image. People do not buy their water heater to project a certain image about themselves. Robot vacuums are frustrating to watch. They get the job done in the end (most of the time) but their random zig zags or difficulty navigating around objects is something most people don’t want to see. They just want the result. Huminoid robots will be like that for a significant amount of time, where they can empty the dishwasher, but it will be painfully slow, odd looking, and very unhuman-like. People won’t want to see this but they will want the job done so they don’t have to do it. A robot that can perform utilitarian household chores would be a huge industry and would be used by most people like a dishwasher or water heater, primarily for its utility.
A robot that reaches the level that it could be a companion, operating visibly with/around people (bringing you and your guests refreshments rather than slowly, awkwardly folding clothes alone in a bedroom while you are at work or downstairs watching a movie) would very likely have a huge pressure to fit cultural and gender dynamics.
