Are Robot Lawn Mowers Efficient?

With humankind’s impact on the planet more in the spotlight than ever before, we’re all looking for ways to reduce our carbon footprint and do our bit to protect the environment.

While in many cases this means going back to basics, the same cannot be said for lawn mowing. In fact, modern robotic lawnmowers are among the greenest of them all! Read on to learn how robot lawn mowers are an efficient addition to your garden toolkit. 

What is a robotic lawn mower?

A robotic lawnmower (or automower, or robomower) is a cordless mower designed to patrol your garden and keep the grass at an optimal length. It carefully cuts your grass, dispersing the clippings behind it as a grass mulch

There are many obvious advantages to robot mowers in terms of saving time and effort – especially if you’ve never been overly keen on shoving a heavy lawnmower around the garden by hand – but the benefits of these machines don’t stop at convenience. 

How are robotic mowers eco-friendly?

One of the primary points of appeal of robotic lawnmowers is that they allow you to replace old-fashioned petrol technology with a machine powered by environmentally-friendly lithium-ion batteries. These long-lasting batteries provide more than enough charge to give your little robot buddy freedom to mow even large gardens with ease, but without the noise and fumes associated with a conventional petrol machine.

As such you won’t have to worry about harmful emissions or noise pollution, so your garden will become a place of tranquillity and you won’t find yourself choking on exhaust fumes. 

More importantly, however, is that over the lifetime of your robotic mower this will significantly reduce your horticultural carbon footprint compared to using a petrol lawnmower. Flymo’s user-friendly 1200R, for example, for example, boasts a level of energy consumption roughly equivalent to that of a 10W light bulb, which is far more efficient than any conventional fuel-burning machine. 

Battery power also offers a variety of additional advantages, such as reduced running costs and eliminating the need to refuel (as your robotic lawnmower will automatically return to its charging station to recharge whenever its battery runs low).

Overuse of fossil fuels has influenced the speed at which the global climate has warmed up, and, surprisingly, petrol lawnmowers are partly responsible.Overuse of fossil fuels has influenced the speed at which the global climate has warmed up, and, surprisingly, petrol lawnmowers are partly responsible.Overuse of fossil fuels has influenced the speed at which the global climate has warmed up, and, surprisingly, petrol lawnmowers are partly responsible.Burning World In Human Hand
Overuse of fossil fuels has influenced the speed at which the global climate has warmed up, and, surprisingly, petrol lawnmowers are partly responsible.

This is important because in the past the only alternative to petrol machines were corded electric mowers, which could only be used in small gardens with access to a power source. Until recently, people with larger gardens had no choice but to use a petrol machine (with the only “green” alternative for effective lawn care being adopting a flock of sheep). But research has shown that using a lawnmower for only one hour can produce as much pollution as four hours of driving a car. 

The development of the robot mower and dependable lithium-ion batteries represents a revolution in energy efficiency, as even the most powerful robotic mowers are infinitely better for the environment than petrol-burning machines. And compared to this the fact that you don’t have to lift a finger to keep your lawn looking great is only a bonus!

It’s not just at home that low-noise, emission-free mowing has appeal though, as robotic mowers are also increasingly used for grounds maintenance work at universities, hospitals, schools and in other public places where lawns need frequent mowing

Here the quiet performance of a robotic lawnmower is especially important, as when mowing in public spaces noisy petrol lawnmowers can become quite the distraction. An automatic lawnmower, by comparison, can even be set to work at night without causing a disturbance. An energy efficient robotic lawnmower can thus help businesses and other organisations maintain friendly relations with those nearby, comply with emissions targets and keep grassed areas in great condition all at once.

Robot Relaxing
Don’t worry; your robotic mower won’t be taking it easy, rather working round the clock to keep your lawn in pristine condition.

And as the demand for robotic mowers grows, so does the range of different machines on the market. Now there are robotic horticulturalists tailored for everything from small lawns to expansive estates, with options available with larger cutting widths and longer battery life for the larger garden. For small to medium domestic gardens an entry level machine like Flymo’s 1200R or Husqvarna’s 305 will fit the bill nicely, keeping areas up to 500m2 well maintained by using clever sensors and a randomised mowing pattern to help your mower negotiate trees, tricky borders and other obstacles. 

Large lawns between 1,000m2 and 2,200m2 might need something a little more powerful to ensure even coverage, but with machines like Bosch‘s Indego, Husqvarna’s  220AC (or the newer 330) and Honda’s Miimo 300 all widely available there are plenty of options open to the discerning hands-free gardener. These mid-range automated machines are more powerful than the entry level models too, so they can even be used to replace a ride-on mower when tending to larger lawns.

The biggest gardens, estates and other properties, however, will need a serious machine to get the job done. For such situations we recommend a mower like Honda’s Miimo 500 or Husqvarna’s  265ACX and 330X Automowers. The Miimo 500 benefits from Honda’s years of experience in robotics and lawnmower design, with hi-tech features sitting alongside traditional mowing technology in one compact package. This includes a range of programmable mowing options and pivoting “swing-back” blades which are designed to ensure safety by bending rather than breaking if they hit a stone, while a maximum mowing capacity of 3,000m2 means that all but the most extensive lawns can be happily maintained.

 Husqvarna’s 265ACX and 330X Automowers can tackle even bigger lawns (up to 3,200m2 and 6,000m2 respectively) with impressive efficiency, while both also boast a variety of clever features. The 330X’s GPS system and automatic passage sensors, for example, mean that it can navigate even the most complicated gardens with ease, and the inclusion of a weather timer (which adjusts the mower’s working time to suit the lawn’s growth rate) ensures exceptional results all year round.

The incredible variety of models available means that the right robotic mower for you will depend upon your particular requirements, though any will do an exceptional job of keeping lawns and other grassed areas maintained without requiring hands-on cutting time.

But whichever machine you choose you can feel good that it provides a much more environmentally-friendly method of tackling routine lawn maintenance than any petrol machine on the market, so investing in a robotic mower is at least as good for Mother Earth as it is for you and your lawn.
