If you have seen a robot dog trotting through a viral video or a trade show, there is a good chance it was a Unitree Go2. It is the cheapest genuinely capable legged robot you can buy in Britain, and with Christmas coming, more people are asking: can I just order one? Yes, from UK dealers, today. But which version you choose, and where you buy it, makes a difference of thousands of pounds.
What is the Unitree Go2?
The Go2 is a four-legged robot made by Unitree Robotics of Hangzhou, the Chinese firm behind many of social media's dancing robots. It weighs about 15kg with its battery, measures roughly 70cm long and 40cm tall, and moves on 12 joint motors, three per leg. A laser scanner on its head, Unitree's own 4D LiDAR, gives it an almost all-round view so it can spot and step around obstacles, and a wide-angle camera sits on its face.
It comes in three main versions. The Air is the entry model: up to 2.5 metres a second (a brisk jog), about one to two hours from its 8,000mAh battery and around two hours to recharge. The Pro adds a faster processor, voice commands, a "side-follow" mode that keeps it trotting at your heel, 3D mapping, a 4G module and a top speed of about 3.5 metres a second. The EDU is the research model, with a depth camera, force sensors in its feet, an Nvidia Jetson Orin computer on board, a bigger 15,000mAh battery for two to four hours, and full access for writing your own software.
What can it actually do?
Out of the box, the Go2 is a superb piece of motion engineering that you drive from a phone app or a games-style controller. It walks, trots and climbs slopes of up to about 30 degrees, rights itself after a tumble, and performs a repertoire of tricks: sitting, stretching, shaking hands, jumping, pouncing and even walking upside down. Unitree says it learned these gaits through large-scale AI simulation, and over-the-air updates keep adding to them. It can carry roughly 7kg on its back.
What it does not do is very much on its own. The Air and Pro will follow you and avoid obstacles, and the Pro can follow a route you have mapped, but neither will fetch your slippers, guard your house in any meaningful sense or replace a pet. If you want it to do new things, you need the EDU and real programming skills: Scan describes only the EDU as supporting full "secondary development", and The Robot Radar notes there is no official upgrade path from an Air. Think of it as a remarkable remote-controlled machine with some autonomy, not a robot that runs errands, although it is serious enough kit that Nottinghamshire Police began testing one in 2025.
UK price and where to buy
Unitree sells through authorised UK dealers, which is the easiest route. These are the prices we found on 1 November 2026, all including VAT:
| Version | Scan | iRed | Availability at Scan |
|---|---|---|---|
| Go2 Air (with controller) | £2,199.98 | £2,394 | Low stock, next-day delivery |
| Go2 Pro (with controller) | £3,119.99 | Not listed | Pre-order, 6–8 weeks |
| Go2 EDU | £7,478.99 | £7,494 | Low stock |
| Go2 EDU Plus | £9,499.99 | From £12,600 (with extra LiDAR) | In stock |
Bolton-based Scan was the cheapest place for the Air when we checked. Its bundle includes the remote controller and a pre-delivery inspection, with specialist DPD delivery at £11.50. Other authorised routes include RoboSavvy, which calls itself Unitree's first authorised UK distributor, and The Robot Group, whose published UK guide prices start at £2,389.98 for the Air and £2,999.99 for the Pro. Prices move, so compare dealers. We found no Go2 sold by Amazon UK.
Buying direct from China: is it cheaper?
Unitree's own online shop lists the Go2 from $1,600 (the Air without a controller), but that is before freight, which Unitree says costs between $399 and $1,000, and before UK taxes, which the store makes the buyer's responsibility. Under GOV.UK rules, goods worth more than £135 sent from abroad attract import VAT, charged on the goods, postage and any duty, plus Customs Duty at whatever rate the UK Trade Tariff sets. The courier bills you before handing the parcel over.
At the European Central Bank's rate on 30 October ($1 = about £0.75), a $1,600 Air plus the cheapest $399 shipping comes to roughly £1,490, and 20% import VAT takes that to about £1,790 before any duty or courier fees. That saves perhaps £400 on paper, but you would wait for a back-ordered robot, handle customs yourself and face shipping a 15kg machine back to China if anything went wrong. Unitree also warns that if a parcel is returned because customs clearance was not completed, you pay the freight again. A UK dealer is worth the extra.
Warranty, plugs and other catches
Read the warranty before you buy. Scan lists the Air with a six-month return-to-base warranty; The Robot Radar, a UK price tracker, reports 12 months on the Pro and EDU. UK dealers supply the robot ready for British sockets; if you import, check that the charger is rated for 230V mains and fit a proper UK plug rather than relying on a travel adaptor.
Security deserves a thought too. In September 2025, researchers disclosed a flaw nicknamed UniPwn in the Bluetooth set-up system of several Unitree robots, including the Go2, that could let an attacker nearby take full control. Unitree said it had completed most of the fixes and would roll out updates. Keep the firmware current, and security experts quoted by IEEE Spectrum suggest keeping the robot on an isolated Wi-Fi network.
Finally, a 15kg robot with fast-moving legs is not a toy for small children, the battery lasts an hour or two, and spares are expensive: Unitree lists Go2 batteries from $500. If you plan to take it out in public, check whether your home insurance covers damage or injury it might cause.
Cheaper alternatives
If £2,200 is too much, there is no like-for-like rival in UK shops; the alternatives are far smaller. Petoi's Bittle X is a palm-sized, open-source robot dog kit for teenagers and adults who want to code, which we cover in our coding robots guide. KEYi Tech's Loona is a wheeled "petbot" with plenty of personality, around £519 in our October gift guide, although Amazon UK was not selling it directly on 1 November. Sony's aibo, the most famous robot dog of all, is not sold in the UK: Sony ended Japanese sales in June and now sells it only in the US, at $3,199.99. At the other extreme, Boston Dynamics' Spot, the robot McLaren uses on UK building sites, is a business tool costing many times more.
Our verdict
The Unitree Go2 is the most capable robot dog an ordinary UK buyer can actually order, and the Air at about £2,200 from a UK dealer is the sensible starting point for enthusiasts who want to marvel at how it moves. Skip the Pro unless voice control and following really matter to you, and buy the EDU only if you plan to write code, because you cannot upgrade later. Do not import to save a few hundred pounds. And go in with clear eyes: this is an astonishing gadget and a brilliant teaching tool, but not yet a useful household helper.
