Side-by-side comparison of 1X Technologies and Sunday Robotics — pricing, features, and use cases. Reviewed by our editorial team in Jun 2026.


1X Technologies and Sunday Robotics represent fundamentally different philosophies for home robotics in 2026.
1X's NEO is a bipedal, anthropomorphic robot targeting early adopters willing to accept teleoperation, while Sunday's Memo is a wheeled platform emphasizing autonomous operation through real-world data training via Skill Capture Gloves.
As of June 2026, NEO is entering pre-order fulfillment with consumer delivery occurring, though relying on human teleoperators for most tasks. Memo remains in beta phase targeting 50 Founding Families, with broader availability deferred to post-2026.
1X's approach prioritizes hardware sophistication with 22-degree-of-freedom hands, tendon-driven actuation, and integration with OpenAI's reasoning capabilities.
Sunday's approach prioritizes data collection at scale, claiming 10 million household routine episodes from 500 homes to train its ACT-1 foundation model for autonomous skill transfer. The choice between them depends on timeline, autonomy expectations, and home layout.
NEO can climb stairs and navigate multi-story homes but currently requires human operators for complex tasks and recharges every 2-4 hours. Memo avoids stairs but operates with greater autonomy in single-floor kitchen and living room environments, with a reported 4-hour runtime from stable wheels.
Both companies target busy households seeking chore automation but via opposite commercialization strategies: 1X demands capital upfront and data sharing, Sunday invests in building proprietary algorithms before scaling to consumers.
For 2026, NEO is the only option if you want immediate delivery and are comfortable with teleoperation; Memo remains aspirational and data-driven but requires patience.
Early 2026 consumer availability and delivery
1X NEO entered consumer pre-orders October 2025 with shipments beginning Q3-Q4 2026; Sunday Memo remains in closed beta phase targeting 50 households with no public launch date.
Autonomous home task capability
Sunday Memo trained on 10 million real-world household episodes, designed to operate without teleoperation; NEO relies on human remote operators for most tasks in 2026 as data collection phase for autonomy.
Multi-story home navigation
1X NEO's bipedal design with vision-only neural networks enables stair climbing and navigation of thresholds; Sunday Memo's wheeled base cannot climb stairs, limiting it to single-floor environments.

Quick answers to the questions readers ask before picking between these two.
Only 1X NEO can climb stairs, thanks to its bipedal design with vision-only neural networks for step navigation. Sunday Memo's wheeled base is mechanically prevented from ascending stairs and remains confined to single-floor layouts. 1X designed bipedalism specifically to overcome this limitation that wheels cannot solve in human homes.
In 2026, NEO relies on hybrid operation: Expert Mode allows human teleoperators wearing VR headsets to control the robot remotely when tasks exceed its autonomous capabilities. Most complex tasks remain teleoperated in early deployment. 1X uses this as a data-collection strategy to train autonomy improvements over time.
Memo is trained using 10 million real household routine episodes captured via wearable Skill Capture Gloves worn by hundreds of Memory Developers, feeding data into the ACT-1 foundation model. NEO uses VR teleoperation data and video-based learning via the 1X World Model. Sunday avoids live teleoperation entirely during the 2026 phase.
1X NEO is available for pre-order with consumer shipments beginning Q3-Q4 2026. Sunday Memo is not available for purchase in 2026; the company is accepting applications for a closed Founding Families beta program targeting approximately 50 households, with broader availability deferred to post-2026.
1X NEO achieves 2-4 hours of active runtime before requiring recharge, limited by bipedal balance energy demands. Sunday Memo achieves approximately 4 hours due to passive stability of its wheeled base, which does not expend energy maintaining balance. Both require frequent charging for extended household use.
NEO prioritizes inherent compliance through tendon-drive actuation that mimics human muscle, allowing gentle yield if it contacts a person. Its 30 kg frame and soft polymer exterior minimize injury risk. Memo emphasizes passive stability through low center of gravity and wheeled base, so it remains standing safely if power is lost.
1X has four years of operational experience with EVE, its wheeled industrial humanoid deployed in logistics and security; NEO leverages those lessons. Sunday emerged from stealth in late 2025, making its approach newer but rooted in data-collection principles from founder Tony Zhao's prior work at Google DeepMind and Tesla.
Choose 1X NEO if you want a humanoid robot in your home by late 2026 and accept hybrid teleoperation as a path to future autonomy.
The bipedal design handles multi-story navigation, OpenAI-backed reasoning provides sophisticated conversation and task planning, and the lightweight tendon-driven frame prioritizes household safety. Expect to share teleoperation data with 1X as part of the training process, and budget for frequent charging.
Early adopters are essentially paying to help train the next generation of autonomous robots while enjoying the status of owning the first consumer-ready humanoid. Choose Sunday Memo if you prioritize autonomous operation, have a single-floor home layout, and value privacy.
The Skill Capture Glove training approach yields robots that learn from real human behavior rather than simulation, eliminating the need for remote operators inside your home. However, availability remains limited to beta testing in 2026, with commercial rollout deferred.
Sunday's longer development timeline reflects a belief that authentic household-scale autonomy requires massive real-world data before consumer deployment—the opposite of 1X's bring-it-now teleoperation strategy.
For affluent early-adopter households comfortable with technology experimentation and privacy tradeoffs in multi-story living: NEO ships in 2026. For patient buyers in single-floor homes demanding autonomous operation and refusing external teleoperators: Memo becomes available post-2026.
