L12-01
Regular price £599.99
With a larger battery and longer boundary wire than the L10, the L12 takes care of lawns up to 800m2 giving you the freedom to relax or get other things done. The L12 independently mows for up to ten hours a day, leaving a neat finish with minimal effort. When the battery runs low, the mower returns to its docking station to recharge. The L12 cuts grass little and often in a random pattern, returning tiny clippings to the surface, naturally fertilising your grass and creating a lush looking, well-manicured lawn. 3 pivoting blades can be adjusted to cut the grass any height from 20mm to 60mm by turning a simple dial. For safety and security, the mower locks with a PIN code and 'bump and lift' sensors ensure that the blade stops if the mower is lifted or bumps into obstacles on the lawn. Navigates slopes of up to 35% (19º) inside the boundary area, and up to 17% (10º) at the boundary wire. IPX5 rated, the L12 can be easily cleaned with a low pressure garden hose. Once installed, the L12 requires minimal interaction. Installation and programming is straightforward, with supporting quick start guide and step-by-step video found on our LawnMaster Support page. The mower includes a built-in USB port for any firmware updates. Includes charging station, power supply, 180m boundary wire and 300 pegs. L12-01

FAQs
The LawnMaster L12 is a robotic lawnmower that will mow your lawn independently, freeing you up to either relax or get stuff done while the lawn is taken care of. The robot mower will alternately mow and charge, returning automatically to the charging dock when the battery is low. The mower is contained within the lawn by a boundary wire which is connected to the charging station. The charging station sends a safe, low voltage signal along the boundary wire which the mower senses and won’t go past. The boundary wire should be laid around the area that is to be mowed and can be used to exclude the mower from certain areas and obstacles, such as trees, shrubs, raised beds and ponds.
Installation requires a boundary wire to be laid around the perimeter of the cutting area and connected to a charging station. This is simple but may take some time. However, the time spent setting up is one-time only, and is repaid by many hours of effort-free lawn maintenance!
The LawnMaster L12 mows little and often, shaving just the very tips off the grass with 3 sharp metal blades. These tiny clippings are not collected but are instead returned to the lawn surface where the nutrients contained in them fertilise the soil. This means stronger, healthier grass with less need for supplemental fertiliser. It also means no grass clippings to dispose of or compost.
No, the LawnMaster L12 will automatically return to the charging station by navigating anti-clockwise along the boundary wire when the battery is low. If the mower is charging within the mowing duration, it will resume mowing when the battery is fully charged again. If the mower is still charging when the mowing duration has ended, it will remain on stand-by in the dock until the next day.
If you have two lawns which are connected by a corridor or path which wider than 1m and all on the same level, the L12 can navigate this as part of normal operation. We would not recommend that you attempt to allow the robot to navigate a corridor of gravel, as this may damage the cutting mechanism. If you have multiple lawns separated on different levels or separated by obstacles which would prevent the robot mower from gaining access (such as a fence), the machine will need to be moved manually to the secondary lawn. In order to do this, the boundary wire is set up as normal around the main lawn, and the secondary lawn is wired up as an island.
For more details on how to set up the L12 to mow secondary lawns, please refer to the instruction manual.
