The short version

A robot dog in 2026 costs anywhere from $1,600 to a six-figure quote, and the honest answer depends less on the robot than on which trim, which seller, and which week. Every price below was re-checked against a live product page on 2026-07-29.

Unitree Go2 — $1,600 (AIR) to $4,500 (X) direct; EDU is quote-only from Unitree, or $11,200–$13,250 at RoboStore.
Deep Robotics Lite3 — $2,890 (Basic) direct or at RoboticsSelect; other trims run $4,950 to $18,000 depending on the reseller.
Xiaomi CyberDog 2 — ¥12,999 in China (roughly $1,800); the US gray-market price is $2,999 and currently out of stock anyway.
Boston Dynamics Spot — no published price at all. Quote-only, and the last public number was $74,500 in 2020.

The price table, by trim

Robot / trim	Direct	US reseller	Verified
Go2 AIR	$1,600	$2,100 clearance (Top 3D Shop, 1 left)	2026-07-29
Go2 PRO	$2,800	$3,750 sale (RoboStore — sold out)	2026-07-29
Go2 X	$4,500	—	2026-07-29
Go2 EDU	quote-only	$11,200; EDU+ $13,250 (RoboStore)	2026-07-29
Lite3 Basic	$2,890 (sold out)	$2,890 in stock (RoboticsSelect); $4,995 (Robots International); RC bundle $4,950 backordered (Maverick)	2026-07-29
Lite3 Venture	quote-only	$5,995 (Robots International); $6,500 backordered (Maverick)	2026-07-29
Lite3 Pro	quote-only	$9,995 (Robots International); $12,000 (Maverick, 1 in stock)	2026-07-29
Lite3 LiDAR	quote-only	$14,500 (Robots International); $18,000 (Maverick, 1 in stock)	2026-07-29
CyberDog 2	¥12,999 (China only)	$2,999 gray import (Giztop — out of stock)	2026-07-29
Spot	quote-only	not sold through resellers	2026-07-29

Two patterns worth naming. First, the reseller spread on the Lite3 is still wild: the same Basic robot is $2,890 at RoboticsSelect and $4,995 at Robots International, verified the same day. Second, availability is the real constraint on the Go2 right now — shop.unitree.com shows the PRO backordered with about a month to ship, and RoboStore’s Go2 Pro page has shown sold-out on four consecutive weekly checks. The prices are stable; the stock isn’t.

What sits on top of the sticker

Shipping and import. Unitree’s own shop quotes $399–$1,000 shipping on a Go2, and buying direct from China means you handle customs. Deep Robotics’ US shop currently advertises free international shipping (plus a 5% EDU5OFF code on the Lite3 series), and RoboticsSelect ships the Lite3 free curbside — on a sub-$3,000 robot, that difference is real money.

Batteries are the recurring cost. A spare Go2 pack is $500 direct from Unitree (both the standard BT2-05 and long-endurance BT2-06 showed $500 at our check) or $560 at RoboStore. Deep Robotics publishes no Lite3 battery price at all — budget blind or ask before you buy. And at the far end, IEEE Spectrum’s launch-pricing report put a Spot battery at $4,620 — the accessory costs more than a Go2 X.

Controllers and chargers. Go2 remote controller: $300 direct, $375 at RoboStore. Spare charger: from $100. Small numbers, but they’re how a “$1,600 robot” quietly becomes a $2,500 order.

Warranty is part of the price. The Go2 AIR carries only a 6-month warranty; PRO, X, and EDU get 12 (and RoboStore backs its EDU units for 12 months in the US). The Lite3’s official manual gives electronics a year but joints, legs, and the battery just 6 months — cut to 3 if you unlock AI Motion Mode. One caveat on a tempting listing: Top 3D Shop’s $2,100 clearance Go2 Air advertises a 1-year warranty, which is more than Unitree itself offers on that trim — get that in writing before you count on it.

The CyberDog 2 asterisk

It’s on this page because people search for it, but in 2026 it is not really a US option. Xiaomi sells it in China at ¥12,999 — we could not reach mi.com’s product pages from the US this week to re-confirm, and third-party trackers report it still on sale there — and the one established gray-market channel we track (Giztop, at $2,999) has been out of stock since at least early July. No official US channel, no US warranty. If you want a sub-$3,000 robot dog you can actually receive and get supported, the Go2 and Lite3 are the list.

The Spot asterisk

Spot has no public price and hasn’t since Boston Dynamics retired its online store. The product page routes you to a sales team, full stop. The reference points that exist are historical: $74,500 bought the 2020 Explorer kit (robot, two batteries, charger, tablet, case, shipping), with launch-era add-ons like the Enhanced Autonomy Package at $34,570 and the premium Spot CARE service plan at $12,000/yr. Today’s Spot CARE brochure still spells out the service terms — 10-business-day repair turnaround, batteries and chargers excluded — but prices everything as contact-for-quote. Treat Spot as a procurement conversation with a five-to-six figure answer, not a purchase.

Our verdict

For a first robot dog with a price you can actually see, the Go2 AIR at $1,600 remains the floor for the whole category — just know the 6-month warranty and the shipping line push the real number toward $2,000+, and stock is tight this summer. Developers should price the Lite3 at $2,890 from whichever seller isn’t marking it up — and check two, because the spread is a factor of 1.7. Skip the CyberDog 2 unless you’re in China, and approach Spot with a budget conversation, not a credit card.
