Are you looking for the best lawn mower but hate pushing around the heavy options that always seem to top the list? Are you looking for a climate-friendly option that’ll save you time and effort? If the answer is yes, you might be in the market for a robot lawn mower. 

Not only is it light, compact and completely hands-free, but it’s also whisper-quiet and produces zero emissions.

This article will show you how robotic mowers work, why they’re growing in popularity and how to choose the right one for your lawn.

What is a Robot Lawn Mower?

Robotic lawn mowers are not too different from robotic vacuum cleaners. They’re powered by batteries, move on their own and require minimal supervision. Depending on their size, they can cut continuously for 30 minutes or even two hours. When they run low on charge, they return to their docking stations to ‘refuel’ before they finish the job.

Robot mowers are able to track where they’ve been and where they’re going. This ensures that no blade is left uncut. They also come in single-zone or multi-zone models, depending on the size and shape of your garden. Most homes have multiple grassed areas, so multi-zone robot mowers are preferable in these instances.

PRO TIP: Robot mowers also have sensors to detect and avoid obstacles like trees, toys and even pets.

While robot lawn mowers tend to be more expensive than traditional mowers, their compact size and easy operation make them perfect for busy families, seniors or those with mobility issues. The use of battery power is also a climate-friendly option. The Australia Institute’s Climate of the Nation survey revealed that 81 per cent of people between 18 and 34 years old and 67 per cent of people over 55 were worried about climate change [1]. So it’s no surprise that more homeowners are turning to clean lawn mowing options.

‘The shift to battery generates value for many reasons. It delivers opportunities to use renewable energy sources, it improves safety and versatility, and creates no direct emissions, less vibration and lower noise levels.’ - Anders Johansson, Senior Vice President, Innovations and Technology, Husqvarna [2]

The only effort involved in using a robot mower is the setup. This means installing a perimeter wire to protect your garden beds and programming the unit. But once this is done, you can sit back and watch the robot do its thing. When it’s finished, the robot returns to its docking station until its next scheduled mow. As for maintaining robot mowers, it’s as simple as cleaning the blades and buying a new battery every few years. What’s more, robot mowers have weather-proof covers and theft protection, which means you can store them outside all year round.

What to Consider When Buying a Robot Lawn Mower

There’s no doubt that the demand for robotic lawn mowers is increasing. According to a recent report, the market for these units is expected to grow at an annual rate of more than 12% between 2020 and 2025 [3]. In the last year alone we’ve seen more robotic mowers enter the market, many of them with smarter features, longer cutting times and lower prices. If you’re thinking of buying a robotic mower, here are some factors to consider.

Lawn Size

Before making a purchase, measure your lawn. Some robot mowers only cater to small gardens of up to 500 square metres, which means that a small or entry-level unit will suffice. If your lawn is large and full of obstacles, your mower will use more power. This requires a high-capacity battery. Try to find one that is at least 20V so your robot mower can spend more time cutting and less time recharging.

If you’ve got lawns in the front, back and sides, you might need more than one mower. Alternatively, you can get a multi-zone robot mower that can be programmed to scan and cut different areas. For lawns with a gradient, look for large, grippy wheels that prevent slippage.

Cutting Diameter

Robot mowers come with different cutting diameters, but they tend to be smaller than traditional mowers. Generally speaking, a large diameter reduces cutting time, while a smaller diameter increases it.

 If you’ve got narrow pathways, a small diameter might be more suitable. This ensures that ground cover or overhanging plants don’t get damaged. But despite the size, robot mowers have sharp, small blades that cut the grass cleanly and turn it into mulch.

PRO TIP: ‘This can result in a finer mow, and the less drastic cutting can be more beneficial for grass in the long term.' - Harrison Astbury from Canstar Blue[4]


Robot mowers are weather-resistant and can be kept outside all year round. Some also come with covered docking stations, protecting them further. While robot mowers can tolerate wet conditions, try not to don’t operate them during or after rain. Blades can get clogged and give you an uneven finish. Look out for units that have rain sensors. This tells the lawn mower robot to return to its docking station and wait out the storm.

Cutting and Recharging

Cutting and charging times can vary depending on the size of the mower and the condition of the lawn. Smaller units can operate for up to 30 minutes before they need to be recharged; larger units can go for up to 2 hours. Cutting and charging times aren’t really a problem unless you’re in a rush, so even if your mower has a short running time, it’ll travel to the docking station, charge up, then continue the job.

As for cutting styles, many units will mow in a random or even erratic pattern, while others will do it in straight lines. Either way, your mower knows exactly where it’s been – and it won’t stop until the entire lawn is done! 

Smart Capabilities

Thanks to recent advances, robot mowers are getting smarter. While many are programmed through an LED control panel, newer models have Wi-Fi or Bluetooth, making them easy to control remotely with an app. This means you can use your mobile phone to monitor the robot’s progress or schedule a new mowing cycle – even when you’re on holiday. Some robot mowers even have GPS, which can tell you exactly where the mower’s been and where it’s going. It can even help you find it if it’s lost.

You can also deploy safety features like PINs and alarms to prevent theft or use algorithms that calculate how quickly your grass is growing and how often it should be cut. Of course, not all robot mowers have these smart capabilities. When buying a mower, think about the features that suit your lifestyle, tech ability and lawn mowing needs. Just remember, the more high-tech the mower the higher the price!

No growth rate calculations or GPS. Just automatic mowing, self-charging and collision control. Like other robotic mowers, you still need to set up boundary lines to protect your garden beds, but once this is done, you need to do is program it with the Amazon Alexa app and let it get to work.

Equipped with a 20V battery, the MoeBot 800 gives you 45 minutes of cutting time before it needs to recharge. While this isn’t the best time we’ve seen, it isn’t a dealbreaker. It just means that the unit needs to recharge a few times before it finishes the job.

On the plus side, the unit uses an automatic spiral cut pattern, which saves energy and prevents track marks, and it has an anti-theft function that gives you peace of mind when the unit is left outside. It can also handle slopes of up to 24 degrees, and its treaded wheels make light work of slopes and uneven lawns.

Want to learn more about lawn mowers? Check our below guides:


1. Do robotic mowers cut as well as petrol mowers?

The cutting mechanisms in robot and petrol mowers are slightly different. Robot mowers have smaller cutting widths and blades, which means that they take longer to cut, but you should still get the same finish. In fact, the Wall Street Journal tested three popular robotic mowers in 2016, and while they didn’t provide 100 per cent coverage, they came pretty close [5]. However, it’s important to know that robot mowers perform better on short lawns, and the frequent cutting and self-mulching can keep your grass healthier. If your lawn is overgrown or you don’t mow very often, a petrol mower might be more suited to your needs.

2. Can I leave my robotic mower unattended?

Robot mowers are designed to mow and recharge autonomously. After setting up your boundary lines and programming the unit, you can pretty much leave it to its own devices. If there are obstacles in the way, robots can detect them and find alternate routes. However, if the robot hits a boundary or is lifted, the unit will stop. This means you need to move or restart it. But this shouldn’t happen too often if boundary lines are correct and you keep an eye on children and pets in the yard.

3. Are robotic mowers safe?

Lawn mower robots tend to be safer than traditional mowers. If the unit is lifted, the blades immediately stop turning, preventing injury. What’s more, the blades are weaker than traditional mowers and tucked under the body, making them difficult to access. The perimeter wire has a current running through it, but the electrical signal is the same as what you’d find in a telephone cable, which means it poses no risk to adults, children or pets.
