Key facts

Founding

Tau Robotics was founded in 2024 by co-founder Cornelia Weinzierl and Alexander Koch, its CEO. The venture firm Pebblebed invested in the company the same year.⁠[1][2]

Pebblebed describes Tau as working toward general-purpose humanoid robots that can perform a wide range of real-world tasks without being reprogrammed for each one, and as developing the underlying model for this; the company uses humanoid robots driven by human teleoperators to collect the real-world interaction data needed for training, with a focus on whole-body control.⁠[1]

July–September 2026: Humanoid Cleaning Service in San Francisco

In late July 2026 Tau Robotics publicly launched a humanoid home-cleaning service, offered at $30 an hour to selected applicants in San Francisco. Koch said current AI could not yet fully control a humanoid robot on its own, so a person operates each robot from a central location with assistance from AI; he said many of the first customers had previously used house cleaners rarely or not at all.⁠[2][3]

The service launched as a pilot open to 1,000 households. The robots, dressed in black Tau Robotics uniforms and given names such as Chelsea and Elon, vacuum, clean kitchen counters and take out the trash, and each costs $50,000 to make. Koch said the company planned to reach 1,000 cleanings a week in San Francisco by 2027 and expand to other U.S. cities and internationally by 2028, and estimated that human technicians would be phased out around 2028 or 2029 once the robots became more self-sufficient.⁠[4]

Remote technicians wear VR goggles to see through the robots’ eyes and step in when a robot gets stuck on a task; if anything goes wrong, a technician can put the robot into safety mode, which makes it lie down on the floor. As of mid-August 2026 the service was invite-only, with sessions limited to one hour; Koch said the company had eight humanoids in total, most of them used for development.⁠[4][3]

By early September 2026 the service had been running for about a month and had cleaned more than 50 apartments and condominiums in San Francisco. At the time one robot cost $30 an hour and two cost $60, and the company said it planned to offer longer sessions.⁠[5]

Ken Goldberg, a robotics professor at the University of California, BerkeleyUniversity of California, BerkeleyThe University of California, Berkeley (UC Berkeley) is a campus of the University of California system; the University of California was founded in 1868 through a merger of two institutions and moved to Berkeley, California, in 1873.Open the full entry, voiced skepticism about humanoid robots’ current ability to clean homes, saying “it is too early,” and questioned the prerecorded videos supplied by the company; he estimated it would take about another decade for the science to reach the level needed for effective home cleaning. Koch acknowledged the technology’s limits but said tasks such as vacuuming and wiping counters already worked fairly well.⁠[2][4]

Data Collection and Privacy

Tau’s robots carry cameras on the head and both wrists and record each cleaning in full. The company says the video is not a byproduct of cleaning but training data; recording cannot be turned off, and footage from the home, including unblurred faces, is used to train its models, although it is not run through facial recognition. The robots’ microphones are disabled and no audio is recorded; bedrooms and bathrooms are entered only if the customer opts in when booking, and customers can mark other areas as off-limits. The company says it cannot “un-train” a model that has already been trained.⁠[3]

Tau’s privacy policy says footage and other robot data are used to train its AI models and kept indefinitely unless customers request deletion, and the company says it does not sell customers’ personal information or use the footage for behavioral advertising. Koch said the camera system, networking and computers are all the company’s own and that Tau has “full control” over the data it collects.⁠[5][4]

Service, Research and Team

As of November 2026, Tau’s website says it usually sends two humanoid robots per cleaning, for one, two or three hours, supervised live by a human operator; the robots are operated jointly by humans and AI, clean bathrooms, kitchens, bedrooms, living rooms, hallways and offices, and can climb stairs and use elevators. The service remains invite-only via a waitlist. The company plans to extend its robots to tasks such as home repair and maintenance and elderly care.⁠[6][5]

Tau’s team works fully in person at its San Francisco office; its open roles include research positions in world models, reinforcement learning, imitation learning and pretraining, and simulation and evaluation, along with robotics software, data infrastructure and hardware roles.⁠[7]
