Create a smooth, even lawn surface, without lifting a finger. The RLM50 continuously cuts as it travels across your lawn, even over slopes, whilst avoiding obstacles. It navigates the lawn, cutting small pieces of grass every day for a smooth finish, and performs a perimeter check for any changes each week. It also monitors its own battery level and automatically returns to base to recharge. Smart, right?

Smart power.

Our Robot Lawnmower manages its own cut cycles. Just program when to start and end each day, and leave the RLM50 to do the rest. It monitors is own battery use too, never letting it go below 30%, and will cut your lawn for up to 90 minutes* before returning to its base to recharge within 120 minutes. Once charged, it will start mowing the lawn using a different route, ensuring an even cut.

Enjoy the peace
and quiet...

“I love the peace and tranquillity of being in my garden, which can be taken away with the noise of a lawnmower. Our Robot Lawnmower is so quiet, you’ll hardly know it’s there. At just slightly louder than a regular conversation, it’s much quieter than regular petrol, corded, or electric lawnmowers”



Simple set up.

To get your robot lawnmower up and running, you'll need to set your border with the boundary wire provided (check out our Video Instructions or Instruction Manual). Once the charging station is installed, the RLM50 will park up and charge itself, before leaving to follow the programmed schedule. Our technology is super user-friendly too, just enter the choice of cutting programme and when you want it to start.

your cut.

With the mower's LCD panel you can schedule your cut 24 hours a day, with 3 cutting modes to choose between. Standard Mode allows the mower to move randomly across the lawn, cutting in different directions for a universal lawn in a few weeks. Zonal Mode focuses on specific areas and prevents repeat mows of problem areas, and Spot Mode starts from a chosen point and cuts radially.

Technology you can trust.

For safety, the RLM50 uses built-in motion sensors to detect obstacles, and will auto-stop if it encounters an issue (you can also use the emergency stop button if needed). Our automatic lawnmower will stop cutting when it rains heavily and return to its base to recharge until the weather brightens up. And for safety, the RLM50 will trigger an alert if it's lifted off the ground when in use, requiring an anti-tamper 4-digit PIN to turn it off.
