I don't understand how you can sell 40 million units and go bankrupt.
Your pricing model should reflect your real-world costs. If it doesn't, then update your pricing model.
If consumers can't do the new pricing model, then your real-world costs are probably out of wack. Which they would be in this case - there's no reason a vaccum should require expensive backend services.
the problem with disc shaped vacuums is adapting your whole home to make their labor saving make sense. not maps or china or all this other bs.
