The best robot lawn mowers take care of your most major gardening task for you, leaving you with plenty of time to focus on your other pursuits. Yes, these nifty garden robots can take care of all the hard work with you still in control, thanks to the ability to program it from your phone. All you need to do is define the boundary lines for where your mower can reach, and then sit back and relax while it gets to work. 

When buying one of the best robot lawn mowers, it’s a good idea to consider just how big your garden is, so that you can buy a model with an appropriate range. You should also factor in any inclines in your outdoor space, as each robot has a different range of slopes they can tackle, with some being best suited to mostly flat surfaces.

In terms of safety, many of the best robot lawn mowers have precautions built-in, so you don’t have to worry about any potential hazards. That includes automatic shut-off, a clever feature that prevents the blades from turning in the event of a foreign object being discovered. Other handy features include GPS tracking, so you can keep track of your new garden companion, and bumper sensors. 

As you might expect, the best robot lawn mowers can be quite costly, with offerings from top brands including MowRo, Worx, and Husqvarna all designed to make your life a lot easier. If you’re looking for a less expensive way of keeping your garden in shape, why not check out our guide to the best lawn edgers or the best electric weed eaters

1. Husqvarna Automower 315X: Best robot lawn mower overall

The Husqvarna Automower 315X is the best robot lawn mower for added high-spec features.

Reasons to buy
+GPS tracking +Can take on slopes up to 40%
Reasons to avoid
-Expensive -Have to pay more for extras

The Husqvarna Automower 315X is our top pick of the best robot lawn mowers as its 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 affordable robot lawn mower

Also the best robot lawn mower for large hills

Reasons to buy
+Good value+Lots of safety features
Reasons to avoid
-No GPS-Not suitable for large lawns

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 Landroid is a great choice if you have a big lawn

Reasons to buy
+ Ideal for medium to large lawns + Customizable 
Reasons to avoid
-Long charge time-Not great for edges

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: Best robot lawn mower that's quiet in use

This robotic lawn mower works quietly and does a thorough job

Reasons to buy
+Anti-theft protection +Quiet
Reasons to avoid
-Expensive -No app controls

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 lawn mower for small lawns

This superb robot lawn mower is built to tackle tight corners

Reasons to buy
+AIA technology  +Good value
Reasons to avoid
- No remote-control capabilities -Can't be used in the rain

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 robot 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 good 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.

Multi-zone capability
Not all automatic lawn mowers travel to distinct, separate areas to cut grass – for that, you need one with multi-zone 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 multi-zone 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.

Advanced features
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.

What warranties do robot lawn mowers come with?

As with all appliances that you come to rely on, with robot lawn mowers, it’s essential to have a sturdy warranty in the case of any accidents or damage. This is especially important given the high price of robot lawn mowers, as you don’t want your robot to break down early in its life span and end up being a total waste of cash. 

Within this round-up of our top robot lawn mowers, there’s a variation of different warranties, so if peace of mind is essential to you, be sure to factor a longer one in. The shortest guarantees will probably only last one year from your date of purchase, though the cost of the robot will likely be lower. Other warranties could stretch as far as five years, which gives you an indication of how much the manufacturer believes in the longevity of its product. 

Which is the best robot lawn mower for small gardens? 

If you have an outdoor space that’s on the smaller side you’re probably looking for a robot mower that’s more specialized in tidying up corners. If that is the case, then the model that you should primarily be looking at is the Gardena 4069 R80Li. This quiet, well-designed robot lawn mower is ideal for tackling the complexities of smaller spaces, as well as providing top-tier cutting results. 

The Gardena 4069 R80Li is ideal for keeping on top of your smaller garden all on its own, with a sensor that can detect how quickly your lawn is growing and how frequently it needs a trim. It also only takes 50 minutes to charge up, meaning even if it can’t manage your whole garden in one session, it can easily be charged up before it’s sent out for another mow.
