Tau’s cleaning robots enter homes, with humans still in control

Tau Robotics is offering humanoid robot cleaning services in San Francisco while collecting real-world data to train more autonomous machines. Human operators currently guide the robots through cameras mounted on their heads and wrists. Tasks such as folding laundry and making beds require operators to perform movements that sensors transmit to the robots. Cofounder Cornelia Weinzierl says vacuuming and mopping can already run without human assistance.

Home visits demonstrate both practical cleaning abilities and significant limitations. During an initial appointment, a robot struggled with stairs and stopped cleaning after heat disabled its operator’s monitoring equipment. Tau refunded the visit and offered a complimentary return. The subsequent cleaning went more smoothly, with the robot cleaning kitchen surfaces and a toilet, although it left taps dripping, knocked objects over and worked slowly.

The service remains in beta, with connectivity, coordination and reliability still presenting challenges. Cameras inside customers’ homes also raise privacy concerns, while inexpensive autonomous cleaning could eventually threaten livelihoods. Weinzierl points to cleaning’s injury risks and staffing difficulties as reasons to pursue automation. Tau is also considering future applications in mold remediation and home health care, but fully autonomous household cleaning remains a distant goal.
