Xiaomi Says Its Humanoids Worked 8 Hours Sorting Console Parts, Then Withholds the Success Rate

Xiaomi posted a video on November 3 that it says shows humanoid robots working a full eight-hour shift sorting centre console side covers at its Beijing electric vehicle factory, according to Electrek, which reported it on November 4. The clip is labelled "Autonomous, 100x Speed". Xiaomi says the robot covered the station's whole day of production needs.

The number that matters here is not the eight hours but the denominator behind it. Xiaomi has not said how many parts were sorted, what share were sorted correctly, or how often a person stepped in.

What the video shows

Per Electrek's description, the robots pull side covers from bins, carry them to storage racks and place them in slots at the Center Console Side-Cover Sorting Workstation. A cumulative-time clock runs through the footage. Around 1:37 a segment labelled "Dropped Material: Multi-Robot Collaboration" shows a wheeled humanoid upper body assisting two legged robots, and autonomous mobile robots carry the parts bins.

Xiaomi says the robots detected and corrected anomalies on their own and coordinated with the line's control system. It released the video as the company collected awards at the World Internet Conference in Wuzhen, Electrek reported.

From three hours to eight

The earlier milestones came with numbers. On March 2, CnEVPost reported that a humanoid ran three consecutive hours, fully autonomously, at a self-tapping nut installation station in the die-casting workshop. It reached a 90.2% success rate and met the line's fastest cycle requirement of 76 seconds. CnEVPost named the controlling model as Xiaomi-Robotics-0, an in-house vision-language-action model of 4.7 billion parameters.

By July, Electrek's history shows, the success rate on that station had risen to 98% and two harder stations were added, one of them the side-cover job.

The eight-hour run has no equivalent figure. That is the gap.

What Xiaomi has not said

Question	Disclosed?
Parts sorted over 8 hours	No
Success rate over 8 hours	No
Human interventions	No
Power for the shift (swaps, tether, charging breaks)	No
Robot count	Not stated

The power question carries weight. A shift of eight hours on one battery would be a hardware claim; a shift with swaps or charging breaks is a logistics claim. The video and Electrek's account do not say which one this is.

How this compares with Tesla

Electrek notes that Tesla's Optimus robots at the 2024 "We, Robot" event were remotely operated by humans, which Tesla did not disclose at the time. Xiaomi's "Autonomous" label addresses that failure mode directly, but a label on a video is Xiaomi's own statement, not an independent audit. Electrek's verdict is that the demo would be a real milestone if fully autonomous, that Xiaomi deserves credit for publishing real numbers earlier, and that it will wait for more detail.

Electrek also argues that wheeled bases suit factories better than legs because of efficiency, stability, room for larger batteries and fewer actuators. Xiaomi's own footage mixes both forms.

What would change this read

A parts count and an intervention log for the eight hours would settle it. Xiaomi's chief executive Lei Jun has said large numbers of humanoid robots will work in its factories within five years, a timeline Electrek dates to December 2025. The next evidence to look for is a station count and a success rate over a full shift.
