The LawnMaster OcuMow® AMB16-400 is a fully automatic, wire-free robotic lawn mower designed for true plug-and-play mowing straight out of the box. No wires. No apps. No antennas. Simply plug the charging station into an outdoor power socket, place the mower on the lawn, and press start. This OcuMow® automatically manages its mowing cycles and returns to charge as needed, saving you time and effort week after week.

Designed for gardens of up to 400m², this OcuMow® robot lawn mower independently navigates your lawn using a sophisticated combination of High Dynamic Range (HDR) imaging, ultrasonic sensors, and Optical Grass Recognition (OGR™) software. This enables the mower to clearly distinguish between grass and borders, avoid obstacles, and maintain consistent coverage without boundary wires.

For best results, lawns should have clearly defined or raised borders, such as paving, sleepers, or distinct edging, that the camera system can recognise. As with all of our vision-based robot lawn mowers, edge trimming will be required.

OcuMow® AMB16-400 makes frequent, light cuts that promote a healthier lawn. By mulching clippings back into the turf, it recycles nutrients, strengthens roots, and helps suppress weeds, while a random cutting pattern delivers gradual, even coverage.

Operation is refreshingly straightforward. A simple onboard keypad allows you to select pre-set cutting schedules with no complex interfaces to learn. Daylight-only operation supports wildlife-friendly gardening while keeping your lawn looking neat.

For greater control over your garden layout, 5 metres of “No-Go” strip is included. This allows you to easily exclude areas such as newly seeded lawns, ponds, flower beds, or rewilded zones. The mower detects the strip automatically and navigates away without additional setup.

Need to cut a separate area? Simply move the mower to another lawn and activate Drop & Mow mode. It will operate independently until the battery runs low, without requiring extra accessories or installation.

To suit different lawn conditions, the mower offers five adjustable cutting heights between 20mm and 60mm. High-specification, deep-tread wheels provide added grip, allowing it to handle slopes of up to 35% (19°).

Safety features are built in as standard. Lift, tilt and ultrasonic sensors stop the blades immediately if the mower is lifted, tipped, or makes contact with objects, and a PIN code helps prevent unauthorised use.

Compact, capable, and deliberately uncomplicated, the LawnMaster OcuMow® AMB16-400 Robot Lawn Mower proves that smarter mowing doesn’t require more features, just better ones.

Simply smarter mowing.
