US startup Sunday Robotics unveils ACT-2 model, folding clothes with 99% success in new homes

Getting a robot to work in a new home without retraining has always been tough. US startup Sunday Robotics, based in the San Francisco Bay Area, just released its new AI model ACT-2. Its wheeled home robot Memo can now fold clothes with over 99% success in homes it's never seen before.

CEO Tony Zhao says the key is that ACT-2 can transfer skills from one home to another, so there's no need to retrain for every new house. He thinks this breakthrough will speed up home robot adoption, making 2026 a big turning point for the industry.

The company also created a new evaluation standard called Solve. It asks robot makers to clearly state what tasks their robots can do, where they test, and how much extra help is needed in new places. Right now, folding clothes reliably is Memo's first Solve skill. The robot learns by watching humans through a sensor glove, then practices on its own to get better.

Sunday Robotics plans to start a Beta test this fall, letting Memo work in some homes. Zhao says the robot will mostly run on its own, and the company won't collect user data during remote help sessions, to build trust.
