The LawnMaster OcuMow® 18 robotic lawn mower saves you time and effort from the moment it’s yours. Fusing High Dynamic Range camera and sensor technology, with our latest Optical Grass Recognition (OGR™) vision software, OcuMow® 18 detects your lawn and edges for you, so you don’t have to train your robot where to go or laboriously map out your boundaries in an app. For small to large gardens up to 800m2 with mostly well-defined borders and outdoor power.

OcuMow® 18 independently mows from dawn until dusk and automatically recharges itself with the supplied, minimal install, plug-and-play charging station. Simply connect the station to an outdoor power socket and let the mower do the rest. OcuMow® 18 uses a combination of GPS positioning and vision software to return to the charging station when its battery is low, or it’s scheduled to stop. With the plug-and-play charging station and camera navigation, you have the ultimate in low-effort set up and operation.

For OcuMow® 18 to perform at its best, you need a clearly defined border around the perimeter of your lawn, such as dark mulch, paving or gravel, or a raised edge at least 6cm high. Adjustment of lawn borders may be required. See instructional video for more information.

In Schedule mode, using a simple dial and LCD screen interface, you can customise when and for how long you want your robot to be active during daylight hours. OcuMow® 18 has a sophisticated algorithm that cuts your lawn in a randomised pattern. This ensures your whole lawn is cut gradually and evenly, nurturing a healthier lawn over time.

Developed with a detachable LawnMaster MX 24V lithium battery, OcuMow® 18 can also be used in drop-and-mow mode for cutting other lawns, in other locations. Simply take the fully charged mower to the other lawn and choose the spiral or random cutting pattern. OcuMow® 18 will mow until the battery is low and wait on the lawn to be taken back to its charging station. 

OcuMow® 18 cuts and finely mulches grass clippings, depositing them onto the lawn. This returns nutrients to the soil, further encouraging a healthier grass condition. 

No-Go strip can temporarily or permanently cordon off sections of your garden that you do not want OcuMow® 18 to go, such as recently re-seeded patches of grass, steep slopes, ponds or rewilded areas of your garden. The mower detects the strip using on-board sensors and navigates away. 10m of No-Go strip is included in the box.

For slopes up to 35% (19°), high specification, deep-tread wheels provide additional grip. 

Choose your desired grass length from 7 cutting heights between 20mm and 80mm. For best performance, and to encourage healthy lawn growth, use 60mm for longer grass and then gradually reduce the cutting height.

For safety, lift, tilt & bump sensors stop the blades immediately if the mower is picked up or bumps into objects, and a PIN code prevents unauthorised use. Operating only during daylight hours, OcuMow® 18 helps protect nocturnal wildlife, such as hedgehogs, allowing them to roam safely at night.

Supplied with one detachable 4.0Ah MX 24V lithium-ion battery. Every MX 24V 4.0Ah battery is fully compatible with the LawnMaster MX 24V cordless range, including lawnmowers, hedge trimmers, grass trimmers, chainsaws and leaf blowers.
