Warehouse automation is a completely different ballgame to consumer, though. If an Amazon warehouse can replace a $20,000/year human with a Kiva robot, they're happy to pay $10,000 for it. Consumers, on the other hand, would find $500 on the steep side for a robot vacuum, considering they'll also need a regular vacuum to cover the stairs and so on. Consumers' price sensitivity is why Roomba spent years with a plastic product navigating at random by bumping into things and relying more on a brush than a vacuum.
