Quiet mowing

Our new robot lawnmower is so quiet, you’ll hardly know its 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). Which means the RLM50 can operate quietly at any time, without disturbing your gardens peace and tranquillity.

Easy To Use Technology

Our 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, travelling 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.
