| WHICHBOT SCORE | 7.2 / 10 | 7.5 / 10 |
| OUR TAKE | The cheapest way to own a real humanoid right now. Smaller and more of a developer platform than a housekeeper — but it ships. | China’s answer to Optimus — an EV maker converting its car-factory muscle into humanoids, starting on its own production lines. |
