Description
Memo is Sunday’s wheeled, semi-humanoid home robot designed to quietly take over the most repetitive chores in busy households. Instead of focusing on flashy stunts, Sunday positions Memo as an everyday appliance that clears tables, loads the dishwasher, folds laundry and even pulls espresso shots, so families get back time rather than more screens and notifications.

Behind Memo is Sunday’s “Skill Capture Glove,” shipped to thousands of “Memory Developers” who record real household routines in their own homes. That data – around 10 million chore “episodes” from more than 500 homes – trains Sunday’s ACT-1 foundation model to handle long, messy tasks like table-to-dishwasher cycles and sock folding, with an emphasis on zero-shot generalization to new homes it has never seen before.
Physically, Memo is a 1.7 m-tall, 77 kg torso-style robot on a wheeled base, with two multi-DoF arms and simple but capable dual grippers. Its central column can raise and lower the upper body so the arms reach from floor level up to around 2.1 m, giving enough range to pick items off the floor, work at countertop height and access overhead shelves. The design prioritizes passive stability (it doesn’t have to “balance” like a biped), a soft silicone shell and smooth, low-speed motion for safe operation around children, pets and furniture.
Memo is currently pre-commercial: Sunday is taking applications for a 2026 “Founding Family” beta in which about 50 households will receive individually numbered units while the team iterates on reliability, safety and service. Building a single Memo by hand costs roughly $20,000 today, and Sunday has publicly said it’s targeting a future retail price under $10,000 once it can manufacture at scale. That positions Memo as a high-end domestic appliance rather than a factory robot, with Sunday clearly betting on a large installed base of home robots powered by its ACT-1 model over the coming decade.
