Anker is adding an edge-cutting feature to lawn mowers with the Eufy Robot Lawn Mower S2 Max, which it introduced at IFA 2026. Its extendable trimming arm cuts grass around driveways and flower beds. The dual-blade model uses vSLAM navigation to create a 3D map of the garden with built-in cameras; it does not require a boundary wire or a real-time kinematic (RTK) base station. According to Anker, the device can map and mow areas of up to 3.7 acres and operate on slopes of up to 80% (38 degrees). The all-wheel-drive model will go on sale in May 2027 for €3,999; US pricing and availability were not disclosed.
Mammotion also announced the Luba 4 AWD, featuring an attachment that cuts along walls, fences and garden boundaries. The device uses front, side and rear cameras, as well as 360-degree lidar and network RTK, which relies on the cloud for navigation. The company said the triple-sensor system provides “zero blind spots and zero slippage.” Independent front-wheel steering helps the mower change direction without U-turns that could leave tracks.
The 3000F model of the Luba 4 AWD has a capacity of 0.75 acres, the 6000F model 1.5 acres, and the 12000F model 3 acres. The edge-cutting attachment is available only on the 3000F and 6000F. Preorders are expected to begin later this year; pricing was not disclosed.
Why it matters
The addition of edge-cutting attachments aims to reduce the need for manual trimming along walls, driveways, and flower beds with robotic lawn mowers; this makes them particularly relevant to owners of gardens with numerous boundaries. Anker’s approach, which does not require a boundary wire or an RTK base station, offers an option that could influence installation preferences, while Mammotion’s combination of cameras, lidar, and network RTK represents a different navigation approach. The differences in area capacity between the models will require users to also consider garden size and which versions include the edge-cutting feature when choosing a device. However, the prices of Mammotion’s models, the regional sales coverage of both brands, and the practical cutting accuracy of these systems are not yet clear.
