One of the concerns you have when buying a robotic mower is that it will create a lot of noises as it works.

Robot mowers take a long time to mow a lawn and sustained loud noise from the robot may be become a nuisance.

A loud conventional mower is to be expected, but they dont mow from several hours at a time. 

In This Article – We explain how loud you can expect a robotic mower to be and share some great models of robotic mower with ultra-quiet functioning. 

Compared to a spluttering petrol mower robotic mowers are virtually silent

With automated mower technology, loud intrusive noise is a thing of the past.

Almost all robotic mowers for residential use have relatively quiet functioning, meaning you can let them work in your garden for long periods without disturbing you or your neighbours. 

Noise levels vary between models of robotic mower

Some robot mowers are louder than others.

This is because they vary in specifications, engineering and the power of their motor.

Professional robot mowers, or mowers suited to large areas have much more powerful motors, with some models being gas powered, meaning that they will generate much more noise.

As your robot mower ages, you may notice an increase in volume

Despite these robots being whisper quiet, over time, the aging and wear of components may mean that the mower becomes louder.

A prolonged mowing session can also increase the sound level of a robot mower.

Loud noise like rattles and bangs indicate a problem.

If you hear these noises, switch off your lawnmower and take it in for professional servicing.
