Tailos
Tailos (formerly Maidbot) is an Austin, Texas robotics company building AI-powered autonomous cleaning robots for commercial spaces. Its flagship product, Rosie, is a self-navigating commercial robot vacuum that uses self-driving-car technology - LiDAR, 3D depth cameras, and proprietary SLAM - to clean hotels, multifamily buildings, and senior-living facilities with no pre-mapping or setup. The company's pitch is plain: automate the most repetitive, physically punishing parts of cleaning so housekeepers can do higher-value work, with operators saving roughly 54 minutes per labor hour.
