Big humanoid robots are expensive, the actuators still suck, and the control problems are hard. Their big advantage is that they can occupy human-shaped spaces, but struggle to do anything useful.

Not to say we won't get humanoid robots eventually, but I think there's probably some low hanging fruit for people to make some other kinds of solutions. Specialized robots for industrial environment, well-thought out appliances for the home.

It would be a bit surprising if the progression was Roomba -> humanoid robot.
