New Robot Lawn Mowers Can Trim Edges on Their Own

Two companies, Eufy (owned by Anker) and Mammotion, used the IFA 2026 tech show to announce robot lawn mowers that do more than just cut grass on their own. These new models can trim the edges of your lawn and navigate around obstacles, getting closer to replacing manual lawn care entirely.

Eufy Robot Lawn Mower S2 Max

The Eufy Robot Lawn Mower S2 Max uses two blades for cutting and has an extendable arm that trims grass right up to the edge of the lawn — something older robot mowers could not do (The Verge; CNET).

To find its way around, the S2 Max uses built-in cameras to scan the yard and build a 3D map as it moves. This means you do not need to lay buried wires around your lawn or set up a separate GPS antenna in the yard — the mower figures out where it is on its own (The Verge).

It can handle lawns up to 3.7 acres and steep slopes up to 38 degrees. It has all-wheel drive and will go on sale in Europe in May 2027 for €3,999 (The Verge; T3). No US price or release date was announced.

Mammotion Luba 4 AWD

Mammotion's Luba 4 AWD solves the edge-trimming problem differently. Instead of a trimming arm, it uses a snap-on attachment that cuts grass against walls, fences, and garden borders. To navigate, it combines four cameras, a 360-degree laser sensor that detects objects by bouncing light off them, and a high-accuracy GPS system that pinpoints its position to within a few centimeters (The Verge).

The Luba 4 AWD also has front wheels that steer independently, so it can change direction without making U-turns. That should reduce the patches of uncut grass that show up when a mower turns around at the end of each pass.

It comes in three sizes. The 3000F covers up to 0.75 acres, the 6000F up to 1.5 acres, and the 12000F up to 3 acres. The two smaller models use a 17.3-inch cutting width, while the 12000F uses three cutting discs spanning 20.9 inches. One catch: the largest model, the 12000F, does not support the edge-trimming attachment — so the biggest mower lacks the very feature that makes this generation interesting (The Verge). Mammotion plans to open preorders later in 2026 but has not shared pricing yet.

Two Different Approaches

The two products take different paths to the same destination. Eufy's S2 Max relies entirely on cameras to navigate, with no wires or GPS. Mammotion layers cameras, a laser sensor, and high-accuracy GPS together, betting that combining multiple systems covers each one's weaknesses. Eufy's earlier E18 model already used a camera-only approach for smaller yards up to 0.3 acre (eufy), and the S2 Max scales that up to much larger properties.

The shared headline feature is edge trimming. Older robot mowers, including Eufy's own E15 and E18, always left a strip of uncut grass around the edges that owners had to finish by hand with a string trimmer. Both new models aim to eliminate that extra step. When two competing companies show up at the same trade show with different solutions to the same problem, it usually means the industry has agreed that problem is the next thing worth solving.

On price, the two are not yet comparable since Mammotion has not released figures. But Eufy's €3,999 puts the S2 Max well into premium territory — more than many people would pay for a traditional riding mower for a mid-size lawn.

The open question is how well camera-only navigation holds up in tough conditions: low light, heavy rain, and yards with lots of trees that block the visual markers the mower relies on. Mammotion's choice to keep GPS alongside its cameras and laser sensor may be a deliberate safeguard against exactly those situations. Until these mowers have been tested through a full mowing season in varied conditions, buyers are weighing promises against real-world scenarios that robotic lawn care has not fully solved yet.

The bigger picture is clear. Each generation of robot mowers has removed a manual step: first the buried wire, then the GPS antenna, and now the hand-trimming pass around the edges. The category is heading toward a product that handles a lawn from start to finish with no human help beyond the initial setup. The S2 Max and Luba 4 AWD are not the final word, but they close a lot of the gap.
