The best robot lawn mowers do all the hard work for you and give you that freshly cut grass feeling every day.
These outdoor gardening gadgets use boundary wires, which are laid around the perimeter of your lawn where you would like the robot to cut. Whether you want your lawn cut every day or every other day, or even want some areas of your lawn a bit longer than others – the best robot lawn mowers are up to the task.
When it comes to finding the best robotic lawn mower for you, keep in mind the size of your lawn as this will help you determine which machine is best suited. Also, note whether your garden is landscaped or not and how often you will want your lawn clipped. Many of the best robot lawn mowers for hills can manage slopes of up to 30 to 40% – which is pretty steep. Whilst others work best on flat areas of grass. Many of the best robotic lawn mowers are jam packed with safety features to give you peace of mind. This includes the likes of bumper sensors and an automatic shut-off function that stops the blades from cutting if they hit a foreign object.
But of course, the more features a robot lawn mower has, the more money you can expect to part with. We have reviewed a range of the best robotic lawn mowers from the likes of market-leaders Husqvarna, MowRo, and Worx. All of which are priced from around $900 right up to $2,600.

1. Husqvarna Automower 315X: Best robot mower overall
The Husqvarna Automower 315X is our top pick for a great all-rounder robot mower that’s packed full of features. As you would expect from the Swedish manufacturer, this X-line model is loaded with all the features any robotic lawn mower could need. This includes a GPS tracking system, LED headlights, and its own app: Automower Connect. It also has voice control, a spot cutting mode, and anti-theft features.
The Husqvarna Automower 315X is one of the smallest in the brand’s X-line series. But its small size doesn’t mean it has a small capacity. It can cut large gardens up to 1,600m2, plus handle inclines of up to 40% – which is pretty steep!
But all these amazing functions means the model carries a steep price tag. It’s worth noting that this is the most expensive model in our line-up, costing around $2,500. You can find some great other robotic lawn mowers for cheaper, but the price won’t include all the added extras you get with the Husqvarna Automower 315X, like the installation of the boundary wires or LED headlights.

2. MowRo RM24A: Best value robot mower
The MowRo RM24A is the cheapest lawn mower in this guide at $900 but handles the steep inclines (up to 30 degrees). It might not have all the fancy high-tech features other robotic lawn mowers come with, but it does ensure your lawn is consistently cut using its 48-hour cycle.
You could say safety is of the MowRo RM24A’s best features. It has three blades which are tucked away in a protective Mowing Blade Guard. This guard allows grass to pass through but protects against foreign objects. It also has a bump sensor and automatic safety sensors which means the MowRo will reverse and stop the blades if it comes into contact with anything other than grass.
Performance-wise, the MowRo RM24A robotic lawn mower takes 90 minutes to charge fully and can cut for two hours. You can also set a custom cutting height anywhere from 1 inch to 2.5 inches. If you have a medium-sized lawn with some slopes to it, this is the best robot lawn mower for you.

3. Worx WR153 Landroid Robotic Mower: Best robot lawn mower for large gardens
The Worx WR153 is a great choice if you’ve got a medium or large-sized lawn.
Thanks to its clever AIA intelligent navigation technology, this robot mower can cut narrow passageways with ease.
Because this robot mower is smart-enabled, you’ll be able to set it to work via your phone using the app. The Worx WR153 doesn’t mow in straight lines, but instead, works its way across your grass using a zig-zag motion so that the grass is evened out and looks uniform.
Suitable for gardens up to half an acre, this Worx robot mower is also fitted with safety features which mean the blades stop if the mower is picked up or tilted off the floor - great for if you have animals or small children. One fault we did find with this mower, however, is that it’s not great for reaching right to the edges of the lawn.

4. Gardena 4069 R80Li robotic lawn mower: Best quiet robot lawn mower
One of the most talked about features of the Gardena 4069 R80Li robotic lawn mower is its quietness. It operates at 60dB, which is the same level of noise of a normal conversation. The average gas-operated lawn mower operates at 90dB, so if you are looking for a quiet mower, this is the best robot lawn mower for you.
Gardena is a member of the Husqvarna Group – so you can expect many of the high-tech features that come with our top pick model too. This includes: rain sensors, anti-theft protection and SensorControl (SILENO+). The latter monitors how quickly your lawn grows and only mows when it needs to be cut.
However, it is worth highlighting this machine is tailored for small lawns with tricky corners. It cuts a total working area capacity of 8611 sq. ft. and it’s emission-free!

5. Worx WR140 Landroid M 20V: Best robot mower for small lawns
If you are looking for the best robot lawn mower for small lawns that have narrow passageways, you’ll find it in the Worx WR140 Landroid M 20V. That’s because the small device comes with patented AIA technology. This tech enables it to manoeuvre around narrow passageways with a minimum width of 60cm. This lawn mower also doesn’t cut grass in straight lines, but instead, cuts the grass in a zig-zag motion so that the lawn is nice and even. Because of this motion, Worx also claims it can cut your 30% faster than other robot mowers.
The Worx WR140 Landroid M 20V robot lawn mower is also ideal for cutting right up to the edge of flower beds and borders thanks to its 7-inch offset blade. This blade is positioned towards the side of the device meaning that there is less tidying up of the borders for you to do.
With a typical mow time of 50 minutes and a cutting capacity of up to 700m2), the Worx WR140 Landroid is a great option if you have a small lawn with a little incline to it.

How to choose a robot lawn mower
First, consider how big your yard is and make sure the mower can handle it daily. Our best pick can mow up to 0.4 acres of grass – not including your house or other structures on your property – which is the top end of the models we evaluated. Others we reviewed can handle anywhere from 0.25 to 0.33 acres, which is sufficient for small to medium-size lawns.
If you have a hilly yard, pick a model that can climb up and down the inclines with ease. The mowers we reviewed can handle slopes between 22 degrees and 30 degrees, depending on the model. However, the dealers we spoke to say they’ve seen some models handle almost 45-degree inclines with little difficulty.
Even though you generally won’t notice how often your robot lawn mower returns to its base or how long it stays there, you should consider how long it takes to charge the battery, as well as how long the machine runs with a full battery. The best mowers we reviewed last about an hour right off the charger and take a little longer than that to recharge. Battery life doesn’t affect your experience or the results, but it’s a good indicator of how well the machine is designed.
Not all automatic lawn mowers travel to distinct, separate areas to cut grass – for that, you need one with multizone capability. This feature is necessary if your home or business has a small front lawn and larger back lawn that is not directly connected. In this scenario, each lawn is considered a zone. Most multizone robot mowers cover two to four zones.
Programmable mowers can be scheduled to run on particular days at specific times. When buying a robot mower, consider how you program it and what you want it to do. You program some units from the mower base, and others can be set remotely over a Bluetooth or Wi-Fi connection.
As convenient as most robotic lawn mowers are, there are features that put some a cut above the competition. Some models include GPS features that map your yard and track your mower if someone steals it. You can control, configure, and monitor some machines from anywhere you have an internet connection via a mobile app. Some also have rain-detection technology that senses when it’s too wet to mow – a few even continue mowing during a shower.
Considering how expensive these robot lawn mowers are, you should consider the length of the warranty. If a model breaks down early in its life span, you may be able to replace or repair it for free if you’ve registered your warranty properly. Plus, a longer warranty provides peace of mind that the manufacturer is confident the product will last a long time.
Warranty periods vary quite a bit for robot lawn mowers. The shortest warranty in our comparison was one year, for the McCulloch ROB 1000. The Worx WG794 boasts a much longer, three-year warranty. And the five-year warranty for the Denna L600 was the longest warranty in our comparison.
