Unitree's R1 humanoid robot is only about $6000, and it's still a nascent, smallish scale technology. They will come down.

If the future home robots are any good, it saves you from buying a dishwasher and robot vacuum. It can replace a maid/cleaning service and gardener/lawn-mowing service. For anyone paying for those services, it pays for itself.

$1000 isn't that high. Probably about a third of American households have an appliance over $2000, which is still a massive market.

I doubt it'd save you from purchasing a dishwasher - those things are very efficient and not very expensive. Perhaps it'd save you from loading and unloading a dishwasher
