If your conventional lawnmower is becoming covered with overgrown grass in some shady and forgotten portion of your garden, an automated lawnmower could be just the solution.

These ingenious robots can automatically mower your lawn, keeping it healthy and carpet soft at a height. 

For the amount of work they do, these bots can look rather small and do not have an onboard receptacle for grass clippings.

If you have a large lawn, you may be sceptical that these little bots are up to the job. 

But in this article, well reassure you that robotic mowers are capable of covering gardens of any size.

We will outline how much area robot mowers cover, providing examples of some great mowers for gardens of every size and tips for selecting the ideal robotic mower.

Robotic mowers can cover all sizes of backyard

Robotic mowers are designed to automatically cut the grass they encounter, irrespective of the size of the lawn. They have powerful motors and ultra-sharp cutting decks that cut a specific width of grass as they roll around your garden. 

Once programmed they will continue to progressively cut until they reach the lawn boundary and change direction to cut another area. This zig-zag process continues until the total lawn area is covered.

You can select a robotic lawnmower for a specific size of the lawn as manufacturers specify the maximum lawn area that can be mowed.

With the average lawn size in the US being 10,871 square feet (or just over 1000 square meters), your backyard can be readily mowed by a standard domestic lawnmower. 

Were confident that robotic mowers can cover any of the 40 million-plus backyards in the United States with ease!

This is because robotic lawnmowers come in a vast range of models that can handle everything from a small front garden to expansive grounds of multiple acres in size areas up to 5,000m².

These can also achieve full coverage of complex lawns that have remote, narrow passages using advanced technology and a range of high-specification features.

While you are evaluating robotic mowers for their working area capacity also check for these essential features

The size of your lawn is not the only factor to consider when evaluating a robotic mower to buy. Also, look out for these three features that can make all the difference to the performance of a robotic mower on your lawn:


Slopes, inclines and hills can be a major challenge for some models of robotic mower, which will simply give up and stop cutting your lawn.

If you have uneven or hilly grassed terrain, check the maximum gradient of any robotic mower you opt for. Most mowers have a maximum gradient of at least 8.5% and some as much as 40% which is ideal if your lawn is sloped. 

Mowing time

Getting the lawn mowed by a robot is a far more laid back affair than using a regular push-mower or ride-on.

These mowers can take ten hours or more to complete mowing their maximum lawn area. Check the amount of time, the mower will mow before requiring recharging and its speed to get an idea of how quickly it will get your lawn done. 

Rounding up

Robotic mowers deliver exemplary grass-cutting performance on lawns of almost any size. They are an extremely useful invention that will save you hours of yard work and provide you with a carpet soft lawn.
