> – Why it matters: Wire-free, steep-slope mowing could finally make robot mowers hassle-free for tricky yards
Mammotion’s booth at CES 2026 became an impromptu proving ground when the Luba 3 AWD series scaled a steep ramp and dodged a fake hedgehog without human help.
Hill-Climbing Showstopper
The demo rig looked more like a rock-climbing wall than a lawn, yet the Luba 3 scampered up and down the 38.6-degree slope. CNET home-tech editor Ajay Kumar admitted he’d hesitate to walk the same angle.

> Kumar said after watching the course-correction.
Wire-Free Boundary Tech
Every 2026 Mammotion mower ditches buried perimeter wire for a triple-sensor stack:
- Lidar that scans “from ground to treetops”
- Dual-camera AI vision
- Real-Time Kinematic beacons for centimeter-level fixes
The Luba 3 AWD, Luba Mini 2, and Yuka Mini 2 all share the same boundary-free brains.
| Model | Slope Limit | Boundary Wire | Pre-Order Price |
|---|---|---|---|
| Luba 3 AWD | 38.6° | None | $2,399 |
| Luba Mini 2 | TBA | None | TBA |
| Yuka Mini 2 | TBA | None | TBA |
Shipping for the flagship Luba 3 AWD is slated for early March.
Key Takeaways
- 38.6° slope rating beats most residential needs
- No trenching or wire repairs required
- Quick recovery after tapping the demo hedgehog shows smarter obstacle handling
- Real-world testing still needed to validate CES performance
If the production units mirror the booth demo, Mammotion’s 2026 line could reset expectations for what a robot mower can tackle without human prep work.
