Sunday Memo
The home robot from Sunday Robotics — a torso with arms on a wheeled column, about 170 cm and 77 kg, trained on 10 million human demonstrations recorded with the Skill Capture Glove.
What it would mean for your event
Why companies discuss Memo too
Hotels, offices and care homes ask for a robot that tidies up. Memo is the most concrete answer to that question — but so far only in a US beta.
What we do at an event today
A robot that welcomes, talks, shakes hands and entertains — that is our G1 and H2; a credible "robot does the cleaning" demo is not something anyone in Europe can show yet.
Once Memo becomes available
We watch the European launch and will gladly broker it for clients who want a robot in their operations.

Capabilities
- Learning from people: more than 2,000 Skill Capture Gloves recorded about 10 million demonstrations of chores in over 500 homes
- Autonomous "table to dishwasher" task: about 40 m of navigation, 33 interactions with 21 objects including glassware
- Folding laundry and socks, making espresso, putting things away
- The robot can be pushed or repositioned by hand — compliant control

- Developers Tony Zhao and Cheng Chi are the authors of ALOHA, ACT and Diffusion Policy
Where it is deployed
Households
The single target scenario: everyday chores done for people, with emphasis on safety and an acceptable pace.
"Founding Family" beta
About 50 numbered units free of charge for selected US households, planned by the end of 2026; a waitlist of more than 3,000.
Data collection with the glove
Paid "Memory Developers" record chores with their own hands — the data strategy that sets Sunday apart.
Availability at ROBOTio
Sunday Memo: ROBOTio does not currently hire out or sell this model. Sunday does not sell the robot yet; a beta for about 50 US households starts at the end of 2026. Looking for a robot for a corporate event? See the Unitree G1 and H2 from our event fleet — we help you choose the model and plan its role in the programme.
- Hire for events: no
- Sale / import: no — we follow its availability in Europe
- Alternative for events: Unitree G1 (130 cm) or H2 (180 cm) from our fleet
Manufacturer: Sunday Robotics
Sunday (Sunday Inc.) is based in Mountain View, California, founded in 2023 by Stanford roboticists Tony Zhao (CEO) and Cheng Chi (CTO), the authors of ALOHA, ACT, Diffusion Policy and UMI. USD 35M seed (Benchmark, Conviction), USD 165M Series B on 12 March 2026 led by Coatue (with Bain Capital Ventures, Fidelity, Tiger Global) at a USD 1.15B valuation; USD 200M in total, about 70 people.
History
A single-arm shoe-arranging prototype in late 2024, the unveiling of Memo and exit from stealth on 19 November 2025, the Series B in March 2026. The company says a hand-built unit costs about USD 20,000 today and wants to cut the price by at least half at scale — but no retail price has been announced.
ROBOTio's view
We follow Memo as an indicator of where home robotics is heading and for hospitality and care clients. It is not built for the event market; at events we deploy the Unitree G1 and H2.
- For households: information about the beta and the sales date
- For hotels and care: advice on a cleaning robot once it is available
- For events: Unitree G1 or H2 from our fleet

Frequently asked questions about Sunday Memo
- Can Sunday Memo be bought or hired?
- No. Memo is not on sale yet; a free beta for about 50 US households starts at the end of 2026. ROBOTio does not have it in its fleet.
- How much will Memo cost?
- No price has been announced. The company says a hand-built unit costs about USD 20,000 today and series production should cut the price by at least half.
- Is Memo a humanoid?
- It has a human-like torso, head and two arms, but a wheeled column instead of legs and pincers instead of fingers. The manufacturer calls it a home robot.
- How does Memo learn?
- From human demonstrations: the Skill Capture Glove mirrors the robot's kinematics and people record chores with it; the ACT-1 model was trained on about 10 million such episodes.
- Will Memo come to Europe?
- Sunday talks about the USA only for now. We watch it and will inform the people we have on file.
- What does ROBOTio offer instead of Memo?
- Unitree G1 and H2 humanoids with operators for events; for companies that want a robot in their operations, selection advice and market watch.
