You'll be left with loads more time to spend enjoying your garden as the Gtech Robot Lawnmower takes care of your lawn trimming needs for you.

It will keep your lawn in perfect shape, leaving you to relax, light up the BBQ or focus on the flower beds. With 3 cutting modes and seven cutting heights ranging from 2.5cm to 5.5cm, the Gtech Robot Lawnmowers three sharp carbon steel blades will give you an even, greener lawn.

With this fully automatic Robot Lawnmower RLM50, you can look forward to more free time to relax. This robot mower is fully automatic, continually cutting as it travels across the lawn, up and down slopes avoiding obstacles to create a smooth even lawn surface. The robot mower is also smart, checking for changes to the design of the lawn and monitoring its battery status, automatically returning to base to recharge itself, so you don’t have to lift a finger.

Features and Benefits

Gtech's new robot lawnmower is so quiet, you'll hardly know it's there. With a 65 dBA sound level, it is much quieter than regular petrol, corded, or electric lawnmowers (89-96 dBA) and only slightly louder than a regular conversation (60 dBA). This means the RLM50 can operate quietly at any time, without disturbing the peace and tranquillity of your garden.

  • Easy To Use Technology – The technology is very user-friendly, simply enter the choice of cutting program and when to start. Each day, the robot lawnmower navigates the lawn, cutting within the perimeter. Each week the lawnmower performs a perimeter check, traveling around the circuit to check for any changes. The cutting technology is very effective, cutting small pieces of grass every day ensures all the lawn maintains a smooth result.
  • Safety & Security – The Gtech Robot Lawnmower comes with an anti-tamper 4-digit PIN code to avoid any unwanted use that will trigger an alarm if lifted when in use. For safety, the robot lawnmower uses built-in motion sensors to detect obstacles and will auto-stop if it encounters an issue. You can also access the emergency stop button if needed. When it rains, the robot mower will stop cutting and return safely to its base to recharge until the weather brightens up.
  • Simple Set Up – To allow your new Robot Mower to work automatically, you will need to set your garden border with the boundary wire provided using our easy-to-follow Set Up Video Instructions or Instruction Manual. Once the charging unit is installed and powered up the Robot Lawnmower will park in the docking station and charge itself before leaving to follow the programmed mowing schedule. A built-in carry handle allows you to easily pick up and move the unit as required.
  • Runtime – Our RLM50 Robot Lawnmower will manage its own cut cycles, simply program the robot when to start and end each day and leave it to do the rest. The robot lawnmower monitors its own battery use, never letting it go below 30% state of charge. It will cut your lawn for up to 90 mins before returning to base and recharging itself within 120 mins. Once charged it will return to mowing the lawn using a different route, ensuring an even cut.
  • Simple Controls – Access the features of the mower via the LCD panel to schedule your cut 24 hours a day, with a choice of 3 cutting modes. 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 or prevents repeat mows of problem areas. Spot mode will start from a chosen point and cut radially. Using the control knob, you can also select cut heights between 55 and 25mm, for the perfect look.
