Why the manufacturer's store says $100,000

This is the single most misleading number in industrial quadruped procurement, and it is repeated in roundups and quoted back to us in buyer conversations. Here is exactly what we saw when we checked on August 25, 2026 (on October 11, 2026 both pages still showed $100,000.00 and still had no checkout):

• The manufacturer's product pages for the A2 and the B2 both display $100,000.00 USD.
• Both pages also state “Contact us for the real price” and show the product as unavailable.
• Neither page offers an add-to-cart or checkout path. The buying route given is an email to the manufacturer's global sales address.

In other words, $100,000 is a round contact-sales stand-in used on a storefront that is not selling these two models to you. Treating it as MSRP produces a false anchor in both directions: it makes a genuine $76,900 quote look like a 23% discount, and it makes a $31,900 A2 look implausibly cheap for what it is. The transactable prices are the ones below.

Unitree A2 prices, by configuration

The A2 is the lighter, faster of the two lines. Prices read in a US dealer's cart on October 11, 2026 (first read from the live listings August 25).

The A2 listing we read stated: one LiDAR unit, an HD camera, an 8-core CPU with Intel Core i7, a carrying capacity of up to 100 kg, 45° slope climbing, and over five hours of runtime per charge. We reproduce those as the listing stated them. The listings did not spell out, line by line, what the Pro step-up changes — so we do not invent a spec delta for it; that is a question for a written quote.

Unitree B2 prices, by configuration

The B2 is the heavier industrial platform and roughly 2.7× the price of a base A2.

The B2 listing we read stated: real-time gait switching, multiple depth cameras, a 20 kg continuous load carried over 15 km, a 40 kg maximum load, the ability to climb 40 cm stairs, and a 5 m/s top speed.

A note on comparing the two spec sheets: the A2 listing quotes a 100 kg carrying capacity while the B2 listing quotes a 40 kg maximum load. Those are the numbers each listing publishes, measured and defined differently, and we have not normalised them into a single comparison. If load capacity decides your purchase, get the definition — static versus continuous, and over what distance — in writing before you compare the two.

The part most quotes leave out: spares and consumables

For a facility deployment, the configuration decision is usually cheaper to get wrong than the spares decision. A single spare battery for a B2 costs more than a mid-range laptop, and a wheeled conversion package costs more than a whole entry-class robot dog. Prices read in the same dealer's cart on October 11, 2026:

Two practical consequences. First, a realistic B2 line item is not $76,900 — a working deployment with one spare battery, a charger and a protective bracket comes to over $83,000 before any sensing add-ons. Second, several accessory listings publish no price at all (navigation kits and leg packages among them), so a quote that itemises them is worth more than one that does not.

A2 or B2: which one matches the job

• Research, teaching and mobile manipulation platforms — the A2 class. It is the entry point into industrial-grade quadrupeds at roughly a third of the B2's price, and its listing is the one quoting long runtime and steep slope capability.
• Heavy patrol and industrial inspection duty — the B2 class. You are paying for the load platform, the stair capability and the sensing options built around it, including the Helios LiDAR as a separate line.
• Smooth floors, ramps and distance — the wheel-leg variants (A2-W, B2-W). They cost $5,000 to $12,000 more than their legged siblings and trade rough-terrain versatility for speed and endurance on prepared surfaces.
• Multi-unit fleets — ask about spares ratios before unit price. At these prices the spares package, not the robot, is where a fleet quote goes wrong.

What an Industrial Inspection Quadruped Actually Costs in the US — Every Tier, Verified by November 4, 2026

Read at live US listings on October 11, 2026, with the A2 and B2 lines confirmed in the dealer's cart and the B2 line re-read there on November 4, 2026, the ladder looks like this. A wheel-leg platform starts at $13,000 and reaches $32,299 in its inspection build. The A2 class runs $31,900 to $46,900 across its configurations. The B2 class is $76,900 for the legged build and $88,900 for the wheeled one (dealer cart, Nov 4, 2026).

A figure that circulates without a date, a channel or a configuration is not a price you can pay until a seller confirms it: check whether it sits above every configuration actually on sale, and whether the listing behind it is sold out or never says what is included. A price attached to a listing nobody can buy is not what the robot costs, which is why every figure on this page carries the date it was read and the channel it was read on. The cause is the one that distorts the consumer tier as well: figures gathered from different channels, different dates and different currencies get restated as a single US price.

There is a second problem the category guides do not disclose. Some of the most frequently quoted inspection quadrupeds — the DEEP Robotics X30 and M20 families among them — are listed with dollar ranges labelled as estimates. We read their vendor product pages first-hand on August 29, 2026 and found no price published at all. Rather than repeat someone else's estimate, we removed those figures from our own comparison rows the same day and marked them price on request, which they remain. A number we cannot re-verify tomorrow is not a price.

For a budget line, the tier matters more than the model. Wheel-leg platforms in the low five figures cover indoor and paved-route inspection. The A2 class is the outdoor-patrol and payload tier, in the thirties and forties. The B2 class is the IP-rated heavy-duty tier, where the robot alone clears $85,000 before the spares, batteries and sensing listed further up this page. Every figure here was read from a live US listing on the date shown, and is re-read on the schedule at the top of this page.

Frequently asked questions

How much does a Unitree A2 cost?

In a US dealer's cart on October 11, 2026: $31,900 for the A2, $36,900 for the wheel-leg A2-W, $40,900 for the A2 Pro and $46,900 for the A2-W Pro.

How much does a Unitree B2 cost?

In a US dealer's cart on November 4, 2026: $76,900 for the B2 and $88,900 for the wheel-leg B2-W. Add spares — a standard battery is $4,200 and a charger $1,200 — before comparing quotes.

Why does Unitree's own store show $100,000 for the A2 and B2?

Because it is a contact-sales placeholder rather than a price. On October 11, 2026 both manufacturer pages still displayed $100,000.00 USD with no checkout: the A2 page asks buyers to email sales, and the B2 page reads “Contact us for the real price” and marks the product unavailable. The transactable US prices are $31,900 and $76,900 respectively.

What is the difference between the A2 and the B2?

Class and price: the A2 is the lighter platform starting at $31,900, the B2 the heavier industrial one starting at $76,900. Their listings publish load figures defined differently — 100 kg carrying capacity for the A2, a 40 kg maximum load and 20 kg continuous over 15 km for the B2 — so confirm the definition before treating either as a like-for-like number.

Which industrial quadruped is right for inspection duty?

The B2 class, chosen around its sensing rather than its base price: LiDAR is a separate line item at $12,400 for the Helios 5515, and the wheels package that converts duty to prepared surfaces is $23,400. Both belong in the quote, not in a footnote.

What is the lead time?

The listings do not commit to one for a given configuration and quantity, and we do not estimate delivery dates we have not confirmed. We will get a written lead time for a specific configuration and quantity on request.

How we verified this page

Every price on this page was first read on August 25, 2026, and the A2 and B2 configuration figures are re-read automatically every morning. On October 11, 2026 every robot and accessory price on this page was confirmed in the dealer's cart, unchanged, and the cart was emptied without checkout. The B2 and B2-W were re-read the same way on November 4, 2026. The A2 and B2 figures were read directly from their own live product listings that day; the remaining configurations and the accessory prices were read from the same seller's live listings on the same date and cross-checked against our automated daily price capture, which reads each listing independently. The $100,000 manufacturer figures were read from the manufacturer's own storefront pages on that date. We did not copy figures from a price sheet, a press release or another publication, and we did not convert them from another currency. Specifications are reproduced as each listing stated them; where a listing was silent, this page says so. Prices on this class of hardware move, so this page carries a verification date and a review date rather than a claim to be permanently current.
