Can I unlock a base Unitree Go2 to match the Pro later?

Not officially. The speed limit and SDK restrictions on the base/Air trim are Unitree's product segmentation, and while the community has produced unofficial secondary-development routes, they are unsupported and can be closed by firmware updates. Never pay Pro money for a base unit on the promise it can be unlocked — if you need Pro capability, buy a Pro.

How do I tell a Go2 from a Go2 Pro when buying used?

The two look nearly identical, so verify rather than trust the listing title. Check the model designation on the underside sticker, confirm the serial with Unitree if in doubt, and test top speed in the app — a genuine Pro reaches roughly 3.5 m/s where the base trim tops out around 2.5 m/s. Mislabelled trims are the most common dispute we hear about in this category.

Which holds its value better — Go2 or Go2 Pro?

The Pro, clearly. The Resale Index has the Go2 Pro up 18.4% year on year on developer and education demand, while our base Go2 figure is an estimated +6% from a much thinner set of sales. The base trim's buyers are hobbyists, who are more price-sensitive; the Pro's buyers are labs and developers who need the SDK and will pay for it.

Unitree Go2 vs Unitree Go2 Pro — Which to Buy Used?

Last updated 26 August 2026

The Go2 and Go2 Pro share the same chassis, gait hardware, and 4D LIDAR — which is exactly why buyers get caught out. The gap is in what Unitree lets each trim do: the base/Air version is speed-limited in software and has no official SDK, while the Pro adds faster locomotion, more onboard compute, and supported programmability. New, the gap is around £500; used, it narrows to a few hundred pounds, and the used market for both is thin enough that trim mislabelling is a genuine hazard.

Which should you buy?

Choose Unitree Go2

Choose the base Go2 if you want a quadruped to run, follow, and demo from the app and you never intend to write code for it. You keep the same chassis and LIDAR as the Pro for £500 less new and typically £300–£600 less used — money better spent on a spare battery pack.

★ Choose Unitree Go2 Pro

Choose the Go2 Pro if there is any chance you will program the robot. Official SDK access, the higher speed cap, and extra compute are what the used market is actually paying for — the Pro is the trim rising on the Resale Index, and it will be the easier of the two to sell on.

Bottom line

For pure hobbyist use the base Go2 is the value pick, and the hardware you touch is largely the same. For anyone with development ambitions the Pro is worth the premium twice over — once in capability, and again at resale, where SDK-equipped trims are the ones appreciating.
