What is the cheapest quadruped robot you can buy?

The answer: Unitree Go2 Air at $1,600

The cheapest quadruped robot you can actually buy today (August 2026) is the Unitree Go2 in its "Air" configuration, listed at $1,600 direct from Unitree Robotics' online shop. That price appears on the Go2 product page at shop.unitree.com as the "From $1,600.00 USD" starting tier, and third-party trackers list the same $1,600 figure for the Air trim (with the Pro at $2,800 and the research-grade EDU higher still).

Nothing else with four legs, an off-the-shelf checkout button, and a real spec sheet undercuts it. Every credible competitor either costs multiples more, ships only inside China, or is a kit you assemble rather than a finished robot.

Why the Go2 Air wins

Unitree is a Hangzhou-based quadruped specialist whose whole product strategy is to price the entry SKU aggressively and let the higher tiers carry margin. The Air trim keeps the same 15 kg chassis, 12 joints, and roughly 3.7 m/s top speed as its siblings, but strips the 4G module, the follow modes, the LiDAR upgrades, and the developer SDK access that professional buyers want. You get a walking, remote-controllable quadruped with an app, a battery, a charger, and a warranty, for less than the price of an entry-level e-bike.

Two things make that $1,600 real rather than aspirational:

1. It is a published, checkout-ready number on the manufacturer's own store, not a "starting from" figure that dissolves on configuration.
2. Unitree ships internationally direct, so buyers outside China can complete the transaction without a reseller markup or grey-market import.

That combination is rare in the quadruped segment. Most of the field is either enterprise-priced (Boston Dynamics, ANYbotics) or region-locked (Xiaomi, several Chinese startups).

The runners-up, ranked

2. Xiaomi CyberDog 2, roughly $1,785 (if you can get one)

The Xiaomi CyberDog 2 launched in August 2023 at RMB 12,999, which converts to roughly $1,785 at the launch-era exchange rate reported by TechNode and TechCrunch. On paper that is competitive with the Go2 Air. In practice it is not, because Xiaomi restricts primary sales to the Chinese market. International buyers rely on resellers like Giztop, where listings sit closer to $3,000 once export handling is included, and used units on eBay drift into the same band. So the sticker price is lower than the Go2 Air; the delivered price is meaningfully higher outside China.

3. Deep Robotics Lite3, from roughly $2,890 (retailer) to $5,400 (direct basic RC)

The DEEP Robotics Lite3 is the entry-level quadruped from DEEP Robotics, Unitree's closest Chinese peer. Third-party retailer AwesomeRobots lists a starting price around $2,890 for a stripped configuration, while DEEP Robotics' own US shop lists the Basic RC bundle at $5,400 and configurations with LiDAR or a Jetson payload run to $12,999 (Pro) and $18,900 (LiDAR). Whichever number you take, Lite3 is at least 1.8x the Go2 Air on the low end and roughly 3x on the direct-from-manufacturer configuration most buyers actually receive. It is a stronger platform for research (better torque, more expansion), but it is not the price winner.

4. LimX Dynamics W1, low four figures in China

The LimX Dynamics W1 is a wheeled-legged quadruped that LimX has priced aggressively for the Chinese domestic market. Because international pricing and stocked distribution are not yet published, it does not qualify as a cheapest-you-can-buy answer for a global reader.

5. DEEP Robotics Lynx M20, quadruped with wheels

The DEEP Robotics Lynx M20 is a smaller wheeled-legged sibling of the Lite3, marketed toward hobbyists and outdoor delivery experiments. Public pricing is not consistently listed at retail, so it cannot be verified as a low-price winner. Assume it slots above the Lite3 rather than below it.

6. Kit-form builds (MangDang Mini Pupper 2, Hiwonder PuppyPi)

If you are willing to treat a build-it-yourself robot as "buying a quadruped," the MangDang Mini Pupper 2 lists at $899 on Amazon and Hiwonder's PuppyPi and ROSPug range from about $577 to $1,017. These are legitimate walking quadrupeds. They are also the size of a housecat, use hobby servos rather than the brushless quasi-direct-drive actuators in a Go2, and are sold as educational STEM platforms. Treat them as a separate category, discussed below.

7. Boston Dynamics Spot, $74,500

For scale on the top end: Boston Dynamics has priced Spot publicly at $74,500 for the base unit since its 2020 commercial launch, and enterprise packages with the arm and additional sensing run well into six figures. Spot is 46x the price of a Go2 Air. It is a serious industrial inspection tool; it is not in this comparison for value shoppers.

8. ANYbotics ANYmal, quote-only enterprise pricing

ANYbotics, the ETH-Zurich spinout behind the ANYmal, does not publish a list price. Every deployment on record is a large-industrial customer (Petrobras FPSO platforms, BASF chemical plants, Equinor and Aker BP in the North Sea, Woodside in Australia, Petronas in Malaysia, Siemens Energy, GE Vernova, and hyperscale data-center inspection). This is enterprise-quoted equipment sold with a service contract, not a shelf product.

What "beats" the Go2 Air but doesn't count, and why

Mini Pupper 2 and PuppyPi at $577 to $899

If price is the only criterion, these win: a MangDang Mini Pupper 2 is roughly 56 percent of the Go2 Air's price, and a bare Hiwonder PuppyPi is closer to a third. They are also, in payload and capability terms, in a different weight class.

Mini Pupper 2 weighs on the order of 700 grams, uses hobby-grade PWM servos, and is intended as a ROS teaching platform: a walking Raspberry Pi with legs, not a robot you deploy. The Go2 Air is a 15 kg field-capable quadruped with the same drivetrain architecture as its Pro and EDU siblings.

The honest read is that "cheapest quadruped robot" has two answers depending on what a buyer means. If the question is "cheapest thing shaped like a robot dog that walks," it is a Mini Pupper 2 at $899. If the question is "cheapest quadruped that behaves like the robots people show in videos" (autonomous stand-up, real navigation, outdoor terrain), it is the Go2 Air at $1,600. Most people asking the question mean the second one.

Used Spot on secondary markets

Occasional used Spot units surface on secondary markets at deep discounts to the $74,500 list. Those are private transactions without warranty support, and Boston Dynamics gates software updates and repair to accounts in good standing, so a bargain used Spot is a risk profile, not a purchase channel. Not a fair "cheapest available" comparison.

The Unitree Go1, discontinued

Unitree's previous-generation Go1 sold for as little as $2,700 at launch in 2021 and drifted lower over its life. It is no longer the current SKU, is not stocked at Unitree's global store, and does not receive the Go2's firmware line. Historical prices are not shoppable prices.

Gotchas and caveats

"From $1,600" is the Air trim, not a fully loaded Go2. The Air drops voice control, follow mode, the 4G module, some collision-avoidance sensors, and has a reduced top-speed cap versus the Pro at $2,800. Buyers expecting the LiDAR-mapping, obstacle-dodging demos from Unitree marketing videos are looking at Pro or EDU footage. If those features matter, the honest price of "a Go2 that does the video things" is $2,800, not $1,600.

Battery, spares, and accessories are extra. A second battery pack, a hardshell case, and a payload mount together add several hundred dollars. Budget for at least one spare battery if the robot is doing anything beyond desk demos.

Regulatory scrutiny is real and rising. Chinese-origin quadrupeds have drawn export-control and procurement attention in Western markets over the past year, and Unitree Go2 units in particular have shown up in incident reporting: one Unitree Go2 security vulnerability documented remote-hijack exposure in 2024, and a July 2026 FCC filing queued a foreign-robot incident line for Unitree. Buyers using the platform for anything sensitive should air-gap it and treat the vendor cloud as untrusted. This does not change the price; it changes the total-cost calculation.

Warranty and repair for direct-imported units. Buyers outside Unitree's serviced regions may find that a warranty claim requires shipping the unit back to China. Factor that into total cost of ownership if reliability matters.

Prices move. All figures here are as of August 2026 from vendor pages and published launch prices. Unitree in particular has re-priced the Go2 line more than once, and Chinese-market prices in RMB do not always convert linearly to US retail. Reconfirm at checkout.

Bottom line

For a global buyer clicking "add to cart" on a manufacturer-supported quadruped in August 2026, the Unitree Go2 Air at $1,600 is the cheapest option. The Xiaomi CyberDog 2 is nominally cheaper at its Chinese domestic price but harder to actually purchase; the DEEP Robotics Lite3 is the next real step up at roughly $2,890 and up; hobbyist kits like Mini Pupper 2 undercut everything but are a different class of machine; and enterprise platforms like Spot and the ANYmal are not competing for this price bracket at all.
