What is a Robot Lawn Mower?

If you haven’t encountered one of them before, you’re probably wondering what they are and how they work. Essentially, these are battery-powered electric lawn mowers that trundle along your lawn clipping it down to your preferred height.

They are fully automatic, use sensors to avoid hazards like flowerbeds, trees, or even bad weather conditions, and work on a schedule that you set manually or via an app.

When their power runs low, they automatically make their way back to a charging station where they recharge and then head out again to complete the job.

They work within a perimeter that you set out yourself, either using a low-voltage wire that you install around the edges of your lawn or, in more advanced mowers, using an app and smart technology that sets different zones for lawns, flowerbeds, patios and so forth.

The Benefits of Having a Robot Lawn Mower

Still need a little more convincing before you buy? Here are more benefits why so many people prefer robot lawn mowers.

Time saver  

There’s no need to spend your weekend morning mowing your lawn yourself, so you can sit back and relax. You can also set your mower to work during the week while you’re at the office, so your lawn is looking pristine on the weekend.

Neat and tidy lawns  

Because robot mowers can be set to work as often as you would like them to, it’s easier to keep your lawn trimmed to the perfect height.

Most people don’t manage to mow their lawns manually once a week, whether due to other commitments, the need to relax, or bad weather.

This means it gets long, leggy and overgrown, and then it gets cut back severely, causing lawn damage. This way, your lawn gets mowed every week, keeping it thick and healthy. 

Simple and hassle free  

Because they are electric and use rechargeable battery packs, there’s no maintenance, no need to fetch and store fuel and oil, and no need to service your mower.

Most of them are easy to set up and then they simply run in the background without you having to think about it. More advanced models even have apps, so you can control them regardless of where you are.

Cost-effective  

Robot lawn mowers are not very cheap to buy – yet. But in the long-term, they are very cost-effective because you don’t have to pay for fuel, servicing or maintenance. Not to mention the saving on your time and energy!

Environmentally-friendly, quiet technology  

These mowers run very quietly, emit no fumes, and don’t use fossil fuels. Most are about as quiet as an air conditioner, which means they can run any time of day or night without bothering you or your neighbours.

Boosts lawn health – and no grass clippings  

Because they work continuously, these mowers make very small clippings that simply fall through the lawn onto the soil. This helps to provide nutrition to your grass while saving you the hassle of dealing with full bags of grass clippings

Features to Look for in an Automatic Lawn Mower

As with more traditional lawn mowers, it’s important to get one that is properly suited to your garden and needs. Here are some features to look out for in the best automatic lawn mower.

Battery capacity 

The mower will keep running back to the charging station to recharge itself automatically until the job is done, so battery capacity isn’t as important as you might think.

However, if you have a larger lawn then it’s worth looking at something with larger capacity, as this reduces how much time the mower spends recharging and how quickly the lawn is trimmed as a result. 

Gradient  

Not everyone has a perfectly flat lawn, and the steeper the gradient is, the more powerful the motor has to be to drive up and down the lawn.

Most good quality robot lawn mowers can handle a 20-degree gradient easily, and some can handle even steeper slopes. Not sure what your lawn gradient is?

Here’s a guide on how to calculate lawn gradient accurately.

User-friendly controls  

Control panels allow you to adjust the cutting height and cutting schedule. Wi-Fi capability will allow you to control the mower through a smartphone app remotely and even set perimeters without the need for installing boundary wires. 

Weather sensors  

This is a great feature that is becoming standard, preventing the mower from working if it is wet or rainy. Most models will even shift their schedule automatically to another time or day so that your lawn gets clipped when it’s dry again.

Safety features  

Since they work automatically in spaces where you potentially have delicate plants and belongings as well as pets and young children, safety features are a must!

The best robot lawn mowers have tilt and lift sensors that automatically shut down the cutting blades if it is toppled or lifted up, recessed blades to make sure curious fingers don’t get cut, and sensors to detect obstacles in front of them to prevent damage to the mower as well as plants and belongings. 

Security features  

Good security features will work with the safety features (for example, sounding an alarm if the mower is tipped over or picked up), and help prevent your mower from being stolen.

These features include PIN code locks, alarms and GPS trackers.

These are the Best Robot Lawn Mowers of 2021

WORX is well-known for its award-winning robot mowers, and this is a great example. This is a trimmed-down version of the more advanced options from WORX, but it still has some very advanced features, including auto-scheduling, Cut-to-Edge technology for neat lawn edges, speedier mowing and advanced motor technology to handle slopes and uneven bumps more easily.

It’s very quiet while running and the charging station is unobtrusive. This small model is ideal for small gardens with 500 square meters of lawn, and although it comes with perimeter wiring, it can pair with a virtual fence so there’s no need to install wire boundaries.

It uses a boundary wire that is easy to install, the battery can last up to 3 years (offering 45 minutes of cutting time per charge), and the blades can even handle thicker, longer grass automatically without a problem.

The only downside for some is that there is no app or remote programmability, and it uses a traditional perimeter wire to mark off the lawn space. It's also one of the more expensive options.

If you are looking for hassle-free installation and operation, this is a great robotic lawn mower. It comes pre-installed and doesn’t need a perimeter wire, so it can get to work right out of the box.

Although the lack of automation is something that a lot of people enjoy, the one downside is that you do have to recharge the mower manually – there’s no charging station it can use to self-charge.

It does have bumpers to sense obstacles, it can tell the difference between grass and anything that isn’t grass, and it has 4-wheel drive to maneuverer as easily as possible on tougher slopes.

It has the same sensor technology, performance, safety and security features as it’s bigger cousin, is easy to set up and install, and weighs just 7kgs.

A great option for medium to larger lawns is this robotic mower from Husqvarna. It will mow up to 3200 square meters of grass, handling narrow passages and obstacles easily thanks to advanced sensor technology, and can operate on slopes of up to 24 degrees.

It’s a well-designed and sleek machine that has great smart tech features, including its ability to synch up with Alexa or Google Assistant.

Weather resistant and quiet, it can be scheduled to run at night, mowing for up to 145 minutes before returning to self-charge for 50 minutes.

Able to cut lawns of up to 1000 square meters, this is an affordable and powerful robotic lawn mower with some great technology. It cuts quickly, quietly and efficiently, and can handle slopes of up to 20 degrees easily.

It doesn’t have a rain sensor, so if you only want it to cut your lawn when the grass is dry, you’ll have to fetch it in. With a mow time of 50 minutes before needing a recharge, this unit has slightly less capacity than other models, and there’s no app for remote control.

It does have powerful blades, however, and uses an intuitive Logicut navigation technology to save power, maximise efficiency and even learn routes through your garden.
