There's plenty of machines which are expensive, bulky, single purpose and yet commercially successful. The average American household has a kitchen range, refrigerator, dishwasher, laundry machine, dryer, television, furnace, and air conditioner. Automatic coffee machines and automatic vacuums are less universal but still have household penetration in the millions. I really think the household tasks with no widely available automation are simply the ones that nobody cares enough about doing to pay for automation.
A robot servant that does literally 100% of chores would be a game changer, and I expect we'll get there at some point, but it will probably have to be a one-shot from a consumer perspective. A clever research idea to reach 25% or 50% coverage still isn't going to lead to a commercially viable product.
