You can’t buy Memo yet. As of October 19, 2026, Sunday Robotics’ only way in is an invite-only beta that is free to join and launching in late 2026. The company’s beta program page says general availability depends on how the beta goes, and that it expects to start shipping Memo at scale in 2027–2028. There’s no retail price yet.
Sunday is a Mountain View, California startup founded by Tony Zhao and Cheng Chi. Memo is its first robot: a wheeled machine with robotic arms and a soft silicone shell, built to do household chores without someone steering it remotely.
What Memo can do today
The FAQ on Sunday’s home page lists three skill areas:
- Dishes: collecting utensils, plates, cups and wine glasses, clearing napkins and food scraps into the trash, then loading the dishwasher and starting it.
- Coffee: pulling a shot from an espresso machine.
- Laundry: handling piles of socks, which Sunday calls a new skill.
Sunday adds that it is still improving how reliably these skills work and how well they carry over to homes Memo hasn’t seen. So the list describes what the robot has learned, not a guarantee of what it will do in your kitchen on day one.
Size, speed and safety
From the same FAQ:
- Reach: Memo can lower its arms to the floor or reach up to 7 feet. For most tasks it rests at about 4 feet tall.
- Speed: software caps its pace. For most tasks Sunday trains it to move at about 50% of a person’s natural pace.
- Compliant control: you can push its arms while it works and they give way instead of resisting.
- Passive stability: because it rolls on a wheeled base instead of balancing on legs, cutting power doesn’t make it fall over or drop its weight.
How Memo learns without watching your home
Most home robot companies collect training data by having people remotely drive robots. Sunday takes a different route. It ships a Skill Capture Glove to people it recruits as Memory Developers, who wear it while doing chores in their own homes. The home page says Sunday has shipped thousands of these gloves. That glove data trains Memo’s AI model, called ACT-1, and Sunday published a preview of its successor, ACT-2, on its blog in July 2026.
The practical result for a household: Sunday says Memo doesn’t need a remote human operator learning inside your home. Compare that with the 1X NEO, which offers remote expert sessions for tasks it can’t yet do alone.
The Founding Family beta
The beta page sets out the terms:
- Cost: no cost to participate.
- Access: invite-only. You apply through the form on the page and Sunday chooses participants.
- Timing: launching late 2026. In its March 12, 2026 Series B post, Sunday said the beta would roll out to users in the fall.
- What you get: first access to a limited-edition numbered Memo, delivery and setup in person by Sunday’s team, invites to events, and a say in which skills Memo learns next.
- How it runs: you schedule tasks by voice or through the Sunday app. During the beta, Sunday says it will try a mix of supervised, collaborative and fully hands-off operation.
The page doesn’t state eligible cities or how many households will be chosen. Sunday said in March that it had received thousands of applications.
What Memo might cost
Sunday’s FAQ gives the only official number: building one Memo by hand today costs about $20,000. The company says that isn’t the expected retail price, that mass production should cut costs by at least 50%, and that pricing will be announced closer to launch. Any retail figure you see before then is a guess.
Who’s behind it
Sunday raised a $165 million Series B at a $1.15 billion valuation, led by Coatue, according to its Series B announcement. Other investors named include Bain Capital Ventures, Fidelity, Tiger Global, Benchmark and Conviction.
