I’d Struggle to Walk Up That Hill. Mammotion’s Robot Mower Scaled It With Ease

You can usually count on CES 2026 for some exciting new developments in robot lawn mower technology, and this year is no exception. None have been more intriguing than Mammotion’s 2026 lineup, which includes the Luba 3 AWD, Luba Mini 2 and Yuka Mini 2. CNET’s home tech expert, Ajay Kumar, stopped by the Mammotion booth at CES 2026 for a firsthand look at their latest models. 

The Luba 3 AWD series stole the show, seamlessly navigating obstacles and extreme inclines at the Mammotion demo. (OK, we did see it lightly bump the fake hedgehog on the lawn, but it course-corrected pretty quickly, which isn’t always the case for robot lawn mowers -- something we learned the hard way during testing.)

“I think there's more credibility to the claims that navigation on these is improving,” said Kumar. Maybe the most impressive feature on display was the Luba 3’s hill-climbing abilities. The Mammotion demo had a wall-like incline set up to showcase the Luba 3’s ability to mow steep inclines. “The incline is enough that even as a person with two legs I'd hesitate to climb it,” said Kumar. We watched the Luba 3 run up and down it with ease. The Luba 3 AWD Series has a maximum slope capability of 38.6 degrees -- far steeper than anything you’re likely to need mowed, according to Mammotion.

Going wire-free is another major innovation for robot mowers, and none of the three new Mammotion mowers require physical boundary wires. Instead, the new Mammotion mowers rely on a combination of lidar sensors that scan “from the ground to the treetops,” dual-camera AI vision, and Real-Time Kinematic positioning, which uses beacons to correct a mower's coordinates to improve accuracy. 

We’ll still have to get our hands on the new Mammotion mowers to see how they perform under real-world conditions, but the early returns at CES 2026 were promising. The Luba 3 AWD is currently available for pre-order for $2,399 with an estimated delivery date of early March.
