This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.I watched a humanoid robot clean my apartment. It felt like a taste of the future.—Grace HuckinsWhen I saw an X post about a new humanoid-robot cleaning service in San Francisco, I immediately signed up for the waitlist. I wanted my apartment to feel like The Jetsons, even if just for an hour.The device that arrived at my building belongs to Tau Robotics, a local startup.
