My favorite robot mower just got a worthy successor - no boundary wires required

ZDNET’s key takeaways

• The Mammotion Luba robot mower was launched at CES last month.
• The Luba 3 features Mammotion’s Tri‑Fusion Navigation System, combining LiDAR, RTK, and AI Vision technologies.
• The new AWD robot mower is officially on sale, with shipping dates set for March.

Robot mowers were huge at CES, but one model in particular stole the show for me. Mammotion, a booming robot mower manufacturer, released a new lineup of devices last month, including the Mammotion Luba 3, Luba Mini 2, and Yuka Mini 2.

If you’ve read ZDNET’s robot mower coverage, you’re likely familiar with the Mammotion Luba 2 and how it was my best‑tested robot mower, even a couple of years after its launch. That’s why I’m even more excited about its successor, the Luba 3, which features the company’s new Tri‑Fusion Navigation System, promising improved positioning and navigation. It also starts at $3,300, so it should definitely have the latest tech.

Tri‑Fusion Navigation System

Instead of relying on a physical boundary wire or just an RTK antenna, the Tri‑Fusion system combines three technologies to maintain its position while mowing your lawn: LiDAR, NetRTK, and AI for visual recognition.

• The robot captures a large LiDAR field of full 360 ° horizontally and 59 ° vertically, with a range of up to 330 ft. This generates a live 3D map composed of millions of data points, enabling the robot to detect obstacles within 1 cm and adjust its course accordingly.
• The Mammotion Luba 3 also uses NetRTK, which the company claims provides a simpler way to set up your robot by defining boundaries in the Mammotion app, eliminating the need to install base stations.

I’ve used the Luba 2 consistently in my front and backyards, and it’s the only RTK robot mower that has stayed within the perimeter of my property without fences or physical boundaries. I trust it to mow along the sides of my front yard that border my neighbor’s lawn, and haven’t had issues with it veering off course in well over a year.

Two full‑HD cameras capture images of the robot’s surroundings, which are then processed using an AI chip for object recognition. This AI‑powered visual recognition process rounds out the Luba 3’s navigation system, improving accuracy.

The robot features a 10 TOPS (trillion operations per second) processor, providing twice the perception power and decision‑making speed, enabling instant object recognition of various obstacles, even in shaded or low‑light conditions.

Other Mammotion products announced at CES

Mammotion is also adding new robot mowers to refresh its product lineup. Here are the new products showcased at CES:

• Mammotion Luba Mini 2 – An all‑wheel‑drive compact alternative to the flagship robot mower, featuring the same 10‑TOPS AI chip as the Luba 3. It can cover up to 10,760 sq ft, climb 80 % slopes, and uses a combination of tri‑camera AI Vision and NetRTK to navigate.
• Mammotion Yuka Mini 2 – Featuring DropMow technology, the Yuka Mini 2 is a compact, plug‑and‑play robot mower best suited for fenced‑in yards. After plugging it in and adding it to the app, it navigates in “N” patterns using either LiDAR and Vision or a tri‑camera AI Vision suite.

All new Mammotion products are expected to launch later in 2026.
