Know the warranty rules before anything else
Unitree’s published service terms are strict: coverage is voided by unauthorized disassembly, opening, or modification; out-of-warranty work is billed for testing, parts, labor, and shipping; you pay inbound shipping even on warranty claims (Unitree pays the return only if the defect is confirmed). Their published commitment is repair or replacement within 20 days — documented real-world cases have run ~3 weeks just for parts shipping. Warranty terms are short to begin with: 6–18 months depending on model and tier.
Translation: don’t open the robot, and factor shipping time into any repair plan.
Option 1: RoboStore (official US partner — in-house US repair)
The most significant recent development for US owners: RoboStore performs in-house US repairs for G1, Go2, and B2 — no trans-Pacific shipping. The published structure:
- Remote diagnosis: free for RoboStore customers, $250 deposit otherwise
- Ship-in diagnosis deposits: $600 (Go2) / $1,000 (G1) — covering two-way shipping and diagnosis, credited toward the repair, with a quote before any work
Option 2: third-party shops
- Robotopian (US company, repair center in Shenzhen/HK): G1 and Go2, 90-day parts + labor warranty, claims 24–48-hour repair turnaround vs 30–45 days going through the manufacturer; quote-based pricing.
- Reboot Hub (mail-in, repairs performed in Shenzhen) publishes the only component-level G1 price list we’ve found: sensor recalibration $150–300, actuator replacement $800–1,500, main controller board repair $449–577 (replace $1,538), with a 30-day parts + labor warranty. Those are that shop’s list prices — useful as the only public benchmark for what humanoid repair costs.
Parts
There’s no public Unitree parts catalog. Batteries and accessories are sold directly (Go2 battery from $500, remote $300); everything else goes through a contact-form inquiry. Foot pads are official consumables — wear isn’t warranty-covered, so keep spares.
Our read
For a robot under warranty: RoboStore or your selling dealer, always — third-party work voids what coverage you have. Out of warranty, the calculus opens up, and the published Reboot Hub component prices tell you the stakes: a single actuator can cost 15–30% of a G1’s purchase price to replace. That gap between machine price and repair cost is exactly why we grade serviceability — and why BigBot Garage exists.
