Cheapest real robot:Eilik — a fully offline desk companion
This guide is for buyers who want a home robot that ships today — not a keynote demo — and who want the integration truth before spending. Picks are drawn from a September 2026 market scan of manufacturer stores, dealer listings, and published reviews; every headline price was re-verified on a manufacturer or major-retailer page on September 26, 2026. The part most guides skip is here in every entry: whether the robot has an official SDK, whether it works locally or only through a vendor cloud, and what it actually takes to connect it to Home Assistant or your own AI stack.
Updated 2026-09-26 · Human-reviewed by Brian, 2026-10-10
1. Saros Z70 (robot vacuum with OmniGrip arm) by Roborock
A flagship robot vacuum and mop with a folding five-axis arm that picks up socks, small towels, and light clutter and carries them to a designated spot. It is the only mass-market home robot on sale today that physically manipulates objects. Reviewers rate the vacuum and mop as top-tier and the arm as unreliable, succeeding at pickups roughly half the time.
Works with your own system? Partial and cloud-anchored. It supports Matter for basic vacuum control and has a Home Assistant integration, but that integration authenticates through your Roborock cloud account; the vacuum functions are automatable, the OmniGrip arm is not. There is no open SDK, and the arm is exposed only inside Roborock's own app — you cannot script it or hand it to a local AI system.
The only shipping mass-market robot that can grab and move objects
Flagship-class vacuum and mop performance underneath the arm
Deep September 2026 discounts: $999.99 at Roborock's store, $1,099.99 at Best Buy
Matter support plus Alexa, Google Home, and Siri Shortcuts control
Reviews put the arm's pickup success rate at about 50 percent
No open robot SDK; the arm cannot be controlled by any third-party software
Camera-based navigation and object recognition carry privacy considerations
List price returns to $2,599.99 when the sale ends
Buy it as an elite vacuum that occasionally moves a sock, not as a manipulation platform.

2. Go2 robot dog (Air / Pro / X) by Unitree
From $1,600 (Air); $2,800 Pro; $4,500 X (price checked 2026-09-26)
The default hobbyist robot dog: app-driven walking, stair and terrain handling, follow-me mode, tricks, and camera streaming, with genuinely robust hardware. Out of the box it is a remote-control experience, not an autonomous one. In stock direct from Unitree's store, with some configurations backordered about a month.
Works with your own system? This is the tier trap the sticker price hides. The $1,600 Air and $2,800 Pro officially do NOT support secondary development — Unitree reserves SDK and low-level control for the EDU line (about $11,190 and up), and the $4,500 X gets only partial secondary development. A community project (go2_ros2_sdk and related jailbreaks) enables EDU-like ROS2 control on Air/Pro, but it is unofficial and can void the warranty. If connecting the dog to your own local AI stack is the goal, the honest price is the X or EDU tier, not $1,600.
Cheapest credible quadruped from a major manufacturer
Robust hardware that handles stairs and rough ground
In stock and orderable direct in the US
Go2 X tier adds partial secondary-development support
Air and Pro tiers officially do not support secondary development or SDK control
Official developer access means the EDU line at roughly $11,190 and up
Community jailbreak SDK exists but is unofficial and warranty-risky
No Matter or Home Assistant support at any tier
Buy the Air or Pro for the app experience; budget for the X tier or EDU line, or accept the unofficial community stack, if programming it is the point.

3. Reachy Mini (Lite / Wireless) by Pollen Robotics / Hugging Face
An open-source expressive desktop robot — a motorized head and torso with a camera, four microphones, and a speaker — designed specifically for wiring up your own AI models. It ships as a DIY kit needing about two hours of assembly, with lead times of up to 90 days. The Wireless version carries an onboard Raspberry Pi CM4; the Lite runs tethered to your computer over USB.
Works with your own system? The gold standard here. Everything is open source: Python SDK, open hardware, first-class Hugging Face/LeRobot integration, and a design intent of running your own speech, vision, and LLM models — locally if you choose. No vendor cloud is required for any core function, and integrating it with a home automation or local AI system is the product's stated purpose, not an afterthought.
Fully open-source hardware and software, programmable in Python
Native Hugging Face and LeRobot ecosystem support
Camera, four mics, and speaker make it a natural voice-and-vision endpoint for local models
Wireless version runs standalone on an onboard Raspberry Pi
No arms and no mobility; it is an expressive head, not a worker
Kit assembly required, with shipping lead times up to 90 days
Lite version must stay tethered to a computer
Buyer pays shipping and any import duties
The best purchase in this guide for anyone who wants to plug a robot into their own local AI stack and have that be a supported feature rather than a hack.

4. SO-101 / SO-ARM101 desktop arm kit by The Robot Studio / Hugging Face LeRobot (kits from Seeed and others)
$249.90 (Seeed SO-ARM101 Pro motor kit; assembled kits ~$300–$500) (price checked 2026-09-26)
The standard hobbyist AI arm: a 6-DOF open-source desktop manipulator sold as leader/follower teleoperation pairs for imitation-learning work. The Seeed motor kit is in stock at $249.90 and excludes 3D-printed structural parts, which you print yourself or buy; fully assembled kits from various vendors run roughly $300 to $500. It is a component of the broader LeRobot ecosystem, not a finished consumer product.
Works with your own system? Completely open, by design. Open-source hardware, open-source software, and native support in Hugging Face's LeRobot framework for teleoperation and imitation learning. There is no cloud, no account, and no SDK gate: the entire stack runs on your own machine against your own models.
Cheapest real entry into training robot manipulation with your own AI models
First-class LeRobot support with a large, active community
Everything runs locally with zero cloud dependency
Natural upgrade path to LeKiwi and XLeRobot mobile builds
Not a finished product; it does nothing until you build and code it
Motor kit requires 3D-printed parts you source separately
US tariffs inflate assembled-kit pricing
Hobby-grade servos have real precision and payload limits
The right first purchase for a tinkerer who wants to learn robot manipulation with local AI before spending four or five figures on anything mobile.

5. Loona Petbot Premium by KEYi Tech
$499 (price checked 2026-09-26)
The best-reviewed pet-style wheeled companion: expressive animated eyes, camera-based face and gesture recognition, games, and GPT-4o-backed voice conversation with no subscription currently required. The Premium package includes the robot, charging dock, and a game prop kit. Sold direct by KEYi Tech and through Amazon and Best Buy, with sale dips toward $449.
Works with your own system? Effectively none. Conversation routes through KEYi's cloud to OpenAI, and the app is the only control surface. A block-coding dev mode exists for simple on-device behaviors, but there is no local API, no Home Assistant or Matter support, and no SDK. Its long-term function depends on a small company's servers — the Anki Vector shutdown is the cautionary precedent for this category.
Most capable and best-reviewed companion robot in its price class
GPT-4o voice conversation with no subscription today
Block-coding dev mode allows simple custom behaviors
Widely stocked at major US retailers
Fundamentally a closed, cloud-connected toy, not an integration platform
Conversation features depend on KEYi's servers staying up
No local API and no smart-home standard support
Camera in a cloud-connected device is a privacy consideration
The pick for someone who wants the most entertaining ready-made companion and does not care about integrating it with anything.
Purchase link not yet available.
6. EMO Go Home by Living.AI
$369 (Go Home bundle with station); $289 base unit (price checked 2026-09-26)
A walking desktop pet with over 1,000 facial expressions, face recognition for around ten people, and ChatGPT-routed conversation. The Go Home bundle adds a home station the robot returns to for self-charging and lets it roam a limited desk area on its own. Orders ship in about two weeks from Living.AI's store.
Works with your own system? None. EMO is a sealed product: no API, no SDK, no local mode for its AI features, no Home Assistant or Matter support. Conversation depends on Living.AI's cloud relay to ChatGPT. It is bought for personality, and that is the entire transaction.
Most expressive desktop companion in its class
Face recognition personalizes reactions to household members
Go Home bundle adds self-charging and autonomous desk roaming
Active firmware update history since launch
Closed firmware with no API of any kind
Conversation is cloud-dependent
Zero physical utility; it is a desk pet
Small-company cloud dependency risk
For someone who wants a lively desk pet and accepts that it will never connect to anything else they own.

7. Eilik by Energize Lab
$139.99 (price checked 2026-09-26)
The cheapest credible desktop companion: a palm-sized robot with an OLED face, touch sensors on head, belly, and back, and a repertoire of animated reactions and mini games. It runs fully offline with no app, no account, no WiFi, and no subscription. Multi-unit bundles let two Eiliks interact with each other on a desk.
Works with your own system? None — but uniquely honest about it. Eilik has no WiFi, no cloud, and no API; it is entirely self-contained and offline. That rules out any integration, and it also rules out the server-shutdown failure mode that haunts every cloud companion in this category.
Fully offline: no app, no account, no cloud, no subscription
Cannot be bricked by a company shutting down its servers
Cheapest entry in this guide at $139.99
Two units interact with each other
No API either; it is a sealed self-contained toy
No speech or AI conversation features
Interactions are scripted and finite; novelty can fade
No connectivity means no updates beyond USB firmware
The budget pick, and the only companion here whose offline design means it can never be killed by a server shutdown.

Questions
Why isn't Tesla Optimus in this guide?
Because you cannot buy one. As of mid-2026 Optimus has no public sales channel, no preorders, and no waitlist; units are going to Tesla's own factories and select enterprises. Tesla has targeted consumer availability for end of 2027, and analysts put realistic availability at 2028–2029. Figure 03 is similarly enterprise-only. Any site selling an 'Optimus' today is not selling a Tesla robot.
What about the 1X NEO home humanoid?
NEO is preorderable — $20,000 up front or $499/month, with a $200 refundable deposit, and '2026 priority delivery' still advertised as of September 26, 2026. Treat that date as soft: as of mid-July 2026 no customer delivery had been publicly verified against more than 10,000 preorders. In the Wall Street Journal's hands-on, every complex chore was performed via 'Expert Mode' — a remote human operator driving the robot through its cameras inside the home — and 1X itself claims only about 60–70 percent task autonomy. It is also a closed, cloud-dependent system with no open SDK, and remote operators seeing inside your home is a real privacy consideration.
Can I actually buy a humanoid robot right now?
Yes, with a major catch. Unitree's R1 starts at $4,900 in stock, but the $4,900–$5,900 tiers cannot be programmed and cannot grasp objects — they are demo machines. SDK access requires the R1 EDU at roughly $10,500. The same pattern holds for the G1: the $13,500 base explicitly does not support secondary development, and hackable EDU configs run $43,900 and up. Budget from the tier that does what you want, not the advertised starting price.
Whatever happened to Amazon Astro and Samsung Ballie?
Both are effectively dead. Amazon Astro disappeared from Amazon's store in January 2026, after the business version was discontinued in 2024. Samsung Ballie was quietly discontinued in early 2026 without ever shipping a unit, six years after its first announcement. Big-company home robots have a worse survival record than the niche products in this guide.
Which of these robots work with Home Assistant or a local AI stack?
Honestly: the open-source picks and, partially, the vacuum. Reachy Mini and the SO-101 arm integrate with anything because you control the entire software stack locally. The Roborock Saros Z70 supports Matter and has a Home Assistant integration for its vacuum functions, though it authenticates through Roborock's cloud and the arm is app-only. The Unitree Go2 requires the X or EDU tier (or an unofficial jailbreak) for any real programmatic control. Loona, EMO, and Eilik offer no integration path at all.
Do any of these require a subscription?
None of the seven requires one today. But Loona's and EMO's conversation features run through their makers' cloud servers, so their headline features depend on those companies staying in business and keeping servers on — the Anki Vector shutdown is the standing warning. Eilik, Reachy Mini, and the SO-101 are immune to that failure mode: the first is fully offline, and the other two are open source and locally run.
Why does every price have a checked date?
Prices in this market move constantly — the Saros Z70 was listed at $2,599.99 and sold for $999.99 on the same day this guide was checked — and US tariffs on Chinese-made hardware push dealer and assembled-kit prices around. Every headline price here was verified on the linked manufacturer or retailer page on the date shown. Re-confirm before ordering.
