What does the price gap between Unitree Go2 and Boston Dynamics Spot actually buy?

By the records, the Boston Dynamics Spot is classified Level III: it runs autonomous inspection missions along operator-defined waypoints in mapped environments using LiDAR SLAM. The Unitree Go2 is Level II: it avoids obstacles and follows a person, but where it goes comes from an operator or owner-written SDK routines. Spot carries 30.9 lb of payload against 17.6 lb and lists at $74,500 before payloads, support or training, against $1,600 for the Go2 AIR.

Is the Xiaomi CyberDog 2 the same capability as the Unitree Go2 for less money?

Both are classified Level II and both avoid obstacles in stock form, but the specifications differ. The Xiaomi CyberDog 2 weighs 19.6 lb against 33.1 lb for the Unitree Go2, carries 2.2 lb of payload against 17.6 lb, tops out at 3.6 mph against 8.3 mph, and runs about 90 minutes against 60. Its $1,800 list price sits above the Go2 AIR's $1,600. CyberDog 2 is sold in China only, with Mandarin-primary documentation and no published international warranty or RMA terms.

Can any of these robots autonomously inspect a facility without a human operator?

Only the Boston Dynamics Spot record documents this. Spot is classified Level III: it runs autonomous inspection missions along operator-defined waypoints in mapped industrial environments using LiDAR SLAM, while task adaptation and fallback decisions remain operator-supervised. The Unitree Go2 and Xiaomi CyberDog 2 are Level II. Neither record documents a stock inspection function, and anything goal-directed on either runs through owner-written code against the published SDK or API.

Which of these platforms supports a manipulation arm?

None of these robots' records names a first-party manipulation arm. The Unitree Go2 record describes modular payload mounting for custom sensors and grippers, with a 17.6 lb payload rating. The Xiaomi CyberDog 2 has payload mounting points and a published API for added hardware, with a 2.2 lb payload. The Boston Dynamics Spot record lists a 30.9 lb payload and a base price that excludes payloads, without naming specific attachments.

Can an individual consumer buy any of these robots?

Two of the three, by their records. The Unitree Go2 ships to consumer and developer buyers through manufacturer direct sales and select resellers, from $1,600 for the AIR to $4,500 for the X, with the EDU quoted by sales. The Xiaomi CyberDog 2 ($1,800) is sold by Xiaomi in China only and reaches other buyers through import channels. The Boston Dynamics Spot is sold only to businesses, government agencies and research organizations through a quoted process.
