Keeping your garden in check can be time-consuming and not everyone has the money to pay for a professional landscaper to ensure the area looks its best year-round. One of the easiest ways to make sure your garden looks neat and tidy is to keep the lawn in check, but time can quickly get away from you and before you know it, it’s overgrown and looking a mess. Investing in a robotic lawn mower takes the effort out of maintaining the lawn, meaning you can programme it to run whenever you like without having to lift a finger – it will even charge itself when it’s low on energy, returning to its docking station to recharge before starting up again whenever it’s scheduled to run.

Robotic lawnmowers are available for gardens of all shapes and sizes and are easy to set up and install. They’re quieter than a standard lawnmower and often, so discreet that you won’t even realise they’re doing their job. Some at the higher end of the price bracket also come with additional features, such as Internet connectivity, apps and scheduling capabilities. Depending on the size of your lawn, you may need to choose a model than can cope with a larger area and inclines, as well as one with a sensitive collision sensor if your garden has a lot of ornaments, flower beds and other obstructions. These are ten of the best robotic lawn mowers on the market to suit all different needs, from the basic to the highly customisable.

How to Buy the Best Robotic Lawnmower

Selecting a robotic lawnmower is not the easiest of tasks. The difficulty in selection could be due to a variety of reasons, primary being the expense incurred during purchase. There are several model and variants available in the market today that could be further confusing. All these aspects can make the selection process a bit overwhelming. The unique benefits of buying a robotic lawn mower are plenty with large household and landscaping companies spending as high as USD 1000 to acquire a top of the range product.

The universal benefits to a robotic lawn mower are safety, time-saving, and precision of cutting. This cutting ensures you don’t have to rake the clippings after mowing the lawn. Robotic lawn mowers are also equipped with smart devices and sensors that allow them to navigate around obstacles and different gradients of grass automatically. Most models also come with an auto shut option when the machine comes in contact with a human and an auto-off switch when lifted from the ground.

With all these benefits it may become very confusing to select the best and most viable option for your lawn or garden. We are here to help take the confusion off your minds. With a few excellent qualities, you will be able to gauge the best robotic lawn mower for your gardening needs.

Weight of robotic lawnmowers: Heavy mowers can be difficult to transport and fit in cars. They are also very bulky and can become a hindrance and cause accidents. Heavy robotic lawn mowers tend to leave excessive track marks in the lawn once the butting is done and might make the lawn look untidy or unkept. This pattern is especially visible during humid conditions when the soil and grass might be a little damp.

However, smaller and lighter robotic lawn mowers do not leave visible track marks on the grass. They are also much more comfortable to cartload than heavier ones. Easy to stow and transport, lightweight robotic lawn mowers are a valuable addition to almost any garden.

Best Robotic Lawnmowers Buyer Guide

Robotic lawnmower topography: While purchasing a lawnmower, it is crucial to consider the topography of your garden. Steep gradients and sloping lawns can be slightly challenging for regular lawn mowers. Select a robotic lawnmower that can quickly climb and descent changes in lawn gradients easily. Ensuring your robotic lawn mower is capable of handling different types of areas can help get a precise and elegant cut.

Almost all robotic mowers can conquer flat lawns. However, hilly and uneven gardens need specialized lawn mowers that can deliver outstanding performances despite the gradient or humidity.

Type of robotic lawnmower blade: Robotic lawn mowers come with two primary blades – pivoting and fixed. Fixed blades do not have the scope to move around a lot and are excellent for flat lawns. They are most suited for gardens that are free of obstacles and unevenness. Pivoting blades, on the other hand, tend to work around objects and obstacles allowing the robotic lawn mower to deliver a fantastic performance.

Pivoting blades are more expensive than fixed blades since they perform multiple tasks at the same time. Fixed blades need manual restarting while pivoting blades do not. Before finalizing a robotic lawnmower, it is crucial that you take stock of the need of your garden and plan according to the objects, obstacles, humidity, and topography.

Performance of your robotic lawnmower: At the end of the day, when you invest in an expensive machine, you would want to see a superior quality of performance and precision. Cheap models can run on a charge for approximately an hour and a half before dying out, while the slightly expensive ones can last up to 7 hours on a single charge.

If you require precision cuts in a shorter time, you would need to choose a robotic lawnmower that has a high-performance rate in the first cut. Many models do require re-cutting for an even and precisely manicured lawn.

Lawnmower noise: Noise is another important criterion while opting for a robotic lawnmower. Most robotic lawn mowers can be timed to start and stop the function when you are away from home and help you avoid the noise altogether, but the decibel levels might become a nuisance to your neighbors.

A good quality robotic lawn mower will be able to do the job in the middle of the night (with minimal noise) while you sleep without disturbing your neighbors. Select a robotic lawn mower that automatically keeps the noise to a minimum even an hour after trimming.
