A robot that cleans my toilet would be nice. Sure I could have a dedicated toilet cleaning robot, and a dedicated dishwasher loading robot, and a dedicated pickup-up-crap-off-the-floor-the-kids-have-left-around-robot ... or just something general purpose?

I don't care if it is humanoid or not, but given that our house is built for humans to interact with it seems reasonable that it should fit into that space.
