The leap is not really there yet and it's cheap because you are the product. The robot will be a massive headache, will work poorly for most tasks, frequently break and require maintenance. In exchange for $500/mo and providing those test hours in a novel environment and the data that goes with it, you get to have a robot in your house that occasionally does something right. The bet being made here is that they can turn that data hose into a useful robot before this poor customer experience tanks their brand.
