1. Husqvarna Automower 315X Robotic Lawn Mower
The Husqvarna 315X is the ultimate tool to integrate your lawn care routine into your smart home. Start or stop your robot mower with just the command of your voice using your Amazon Alexa or Google Home device. The Automower can also be controlled via your cell phone through Husqvarna’s Automower Connect app.
The Automower is ideal for lawns up to .4 acres large and can handle slopes of up to 22 degrees, making it one of the best robotic mowers for larger lawns with uneven terrain. GPS navigation lets you keep track of where your mower is in your yard via the Automower Connect app.
You can program your Automower to cut any time, day or night, as the mower has a guaranteed noise level of below 60 decibels, which is the volume of a normal conversation. No more worrying about mowing too early and waking the neighbors up, and you can even program your Automower to cut the grass in the middle of the night. Don’t worry about the weather, either–the Automower runs just fine in the rain!
The Automower 315X has anti-collision sensors, keeping pets and children safe. The 315X has the best anti-theft technology–a PIN code is required to operate the machine, and if the mower is lifted while mowing, an alarm will sound. Your PIN then needs to be entered to restart the machine. If your machine does get stolen, it can be located using GPS technology.
The Husqvarna Automower 315X comes with everything you need to set up your new robot lawn mower, including a docking station and a kit to install hidden guide wires.

2. Worx Landroid L WR155 20V Robotic Lawn Mower
The Worx Landroid L WR155 was the online top-selling robotic mower in 2021. It is one of the best robot lawn mowers for larger lawns and can handle a lawn up to half an acre in size. Its patented AIA (Artificial Intelligence Algorithm) technology allows it to navigate through tighter spaces than other robotic mowers can.
One thing that sets the Landroid apart is its Power Share battery. The same battery used to power your Landroid is compatible with any Worx 20V, 40V, and 80V tools and products. If you have other Worx products, this feature can come in very handy. You can easily replace the battery yourself at home.
The newest Landroid models feature a floating blade disc, which automatically raises the blade to avoid obstacles and uneven terrain, meaning the Landroid gets stuck or trapped less frequently than many other robotic mowers.
The Landroid has a rain sensor, so it will never mow in the rain. If it senses rain, it will immediately return to its charging station, although its casing is waterproof, so the mower will not be damaged by getting a little bit wet. The idea is that cutting a lawn in the rain can lead to sloppy results. However, if you live somewhere where it rains frequently, it might bother you when your mower stops cutting the moment a light rain begins.
The Landroid features a high-efficiency brushless motor that runs longer, is more powerful, and has a longer life when compared to the brushed motors found in many robotic lawn mowers.
The Landroid L WR155 comes with a charging station, 820 feet of boundary wire, and everything else you need to get started using your new robot lawn mower.

3. MowRo Robot Lawn Mower RM24
If you are looking for a simpler machine and don’t have the desire to be able to control your robotic mower through a smartphone or smart speaker, then the MowRo RM24 might be the best robotic mower for you.
Ideal for small to medium yards, the RM24 is recommended for mowing areas of .25 acres or less. With the capability of handling inclines of up to 30 degrees, the RM24 is the best robot lawn mower on our list for yards with steep slopes.
While the RM24 doesn’t have an app or Bluetooth capabilities, it is quite easy to program. The mower will run every 48 hours at the time you choose. If the mower runs low on power before the job is done, it will simply return to the charging dock and fully recharge before picking up where it left off.
Since you choose the mowing time yourself and the mower will never leave the dock at another time, you can be sure that pets and children are safely inside when it is time for the mower to run. However, if a child or pet does come into contact with the mower, they will be safe. The RM24 features a protective mowing blade guard which only allows grass to pass through, keeping little toes and fingers safe.
The MowRo RM24 has an auto-stop safety bumper, which allows it to find an alternate route if an obstacle is in its path. The mower also comes with a rain sensor which will send the mower back to the charging station if rain is detected. The mower will finish mowing the lawn once the rain has stopped.

4. Robomow RX20 Battery Powered Mower
If you have a smaller yard, a smaller mower like the Robomow RX20 might be the best robot mower for your needs. This compact model has many of the bells and whistles of the more expensive mowers but at a more budget-friendly price.
The RX20 can be easily controlled through your smartphone, the web app, or voice activation through Amazon Alexa. You can manage your mower from anywhere at any time.
The smaller 7-inch cutting width allows the RX20 to easily navigate through smaller yards. This mower is only recommended for lawns up to 1/20 of an acre with slopes up to 8.5 degrees, so it is not for you if you have a larger or hilly yard. However, it is ideal for smaller spaces, and buying a more expensive model engineered for larger lawns doesn’t make much sense if this one can do the job.
The RX20 is very fast to set up and easy to use. Installation is complete in less than an hour, and you are ready to mow! The perimeter wire can be set up so that the mower will mow in two separate zones, each time returning to the base station after completion.
The RX20 has a rain sensor, so it will automatically return to its charging base in the event of rain and continue mowing when the weather improves.
While the RX20 is a bit louder than many other robot mowers at 69 decibels, it does feature an eco-mode, which brings the volume down to 64 decibels.
- Lower price point than most robotic mowers
- Can be programmed to mow different zones
- Long charging time
- Can’t handle large slopes

5. Gardena 4069 R80Li Robotic Lawnmower
Another great option for small- to medium-sized lawns is the Gardena 1069 R80Li robotic lawn mower. Gardena is part of the Husqvarna Group, so you can expect a high-quality product with great features.
One great feature of the R80Li is the SensorControl System, which senses how quickly your grass is growing and adjusts the cutting schedule accordingly.
The R80Li does not have any app controls, which may be a drawback for some, but many will appreciate the simple and intuitive controls of the mower. The mower is easy for anyone to use–just install the included perimeter wires, then program the mower with the size of your lawn and mowing time.
With only a 60-65 minute cutting time, in which the machine can mow approximately 50 square meters on one charge, it will likely take many charges to mow your entire lawn. When the mower is running low on power, it will automatically return to its charging station and continue cutting the lawn when fully charged.
The Gardena R80Li is weatherproof and will run in the rain, a feature that sets it apart from many other robotic mowers and makes it ideal if you live in a region that gets a lot of rain.
The R80Li is one of the quietest mowers on the market, with noise levels at 60 decibels or below. You don’t have to worry about your mower running too early or too late any disturbing your neighbors; they likely won’t even hear this quiet mower!
The R80Li has great safety and anti-theft features. If the machine is lifted while mowing, it will automatically stop. A PIN code then needs to be entered to restart the mower. It also has an alarm that you can set to sound if the machine is lifted, adding an extra anti-theft measure.

How Does a Robotic Lawn Mower Work?
A couple of decades ago, owning a robot that mowed the lawn might have sounded like a science fiction fantasy. Now sales of autonomous mowers continue to climb as technology advances, and these luxury items become more affordable for middle-class buyers.
Robotic lawn mowers use technology very similar to the increasingly popular robotic vacuum cleaners. Most mowers require the user to install boundary wire around the perimeter of the lawn. This ensures that the mower will avoid areas you do not want it to mow, such as flower beds. The robot mower cuts the grass randomly, stopping and turning around each time it comes against the boundary wire.
While the random cutting pattern of a robot mower may seem inefficient, it creates a uniform look free of the stripes left by traditional mowers.
The mower will mow the grass either until it has cut the whole yard or until it runs out of battery. When the battery life is close to depleting, the mower will return to its charging base. Most mowers will automatically resume mowing the lawn once it is fully charged.
You should choose a mower with a mowing area close to the size of your yard. If you have an acre of lawn and you buy a mower with a mowing area of .2 acres, the mower will not be able to cut your whole yard. On the flip side, if you have a .2 acre lawn and buy a mower with a mowing area of one acre, you will probably be paying much more than you need for an adequate mower.
But do robot lawn mowers work? The machines are pretty simple and work very well so long as you choose the ideal machine for your yard.
Factors to Consider When Choosing a Robotic Lawn Mower
Because it’s a big investment, there are several different factors you’ll need to consider before settling on a final robot lawn mower choice.
It’s no surprise that robotic lawn mowers are very expensive. Most models cost well over $1000, although some robotic mowers are in the $600-$900 range. For the most part, you get what you pay for. Buying a robotic mower solely based on price is probably not a good idea.
However, many of the most expensive models are designed to cut large lawns and have advanced technological features like GPS, Bluetooth, and WiFi connectivity. If you have a small lawns and are okay going without some of the high-tech features, you might be able to find a high-quality mower on the lower end of the price spectrum.
The voltage of your mower’s battery will tell you how powerful the machine is. Our top five picks range from 12 to 28 volts, which is quite a difference in mowing power. If your mower will need to cut through thick, overgrown grass, a machine with higher voltage will have a much easier time getting the job done.
The mowing area a robotic mower can cover is probably one of the most important factors to consider when buying a mower. The mowing area listed is the largest recommended area the machine is capable of cutting.
The cutting width refers to the amount of grass the mower will cut in one pass. The wider the cutting width, the more quickly the mower will be able to cut your entire lawn. Of course, since the robotic mower is doing the work for you, the time it takes to complete may or may not matter to you.
Different robotic mowers can handle different slopes. If you have a sloped or hilly yard, you need to pay attention to the incline your mower can handle. In our reviews, we listed the cutting incline in degrees. Be aware, however, that some mowers will list a percentage instead. This number can easily be converted to degrees using an online calculator.
Most mowers have different height settings so you can easily choose how long you want your grass to be. The length of your grass will depend on terrain, grass type, and personal preference. Some robotic mowers have a wider range for cutting height than others or cutting deck sizes, so be sure that you choose a mower that will cut the grass to your preferred length.
All robotic lawn mowers are battery-powered, and therefore are much quieter than gas-powered lawn mowers. A gas mower is typically around 90 decibels, while most robotic lawn mowers range in volume from approximately 60 to 70 decibels.
Although all robotic lawn mowers are relatively quiet compared with gas mowers, if you have neighbors in close proximity or if you would like to run your mower at night, you probably want to buy one of the quietest models with a volume of around 60 decibels.
Additional Features to Consider
Do you want a simple robotic mower that doesn’t have many features and customizable options, or do you want to spend some extra money on a mower with all the bells and whistles? Some robotic lawn mower models lack any of these features, while some mowers have all of these features and more.
Security PIN code
Many robotic mowers have a PIN code that needs to be entered in order for the machine to run. If the mower is lifted while running, it will stop running, and the PIN will need to be entered before it will resume cutting. This feature adds a layer of security as a thief would likely not want to take a machine that they can’t get to run.
Many mowers have Bluetooth connectivity, which allows you to control your machine when you are within close range. However, a mower with WiFi connectivity can be controlled through an app on your smartphone from wherever you are. You could even be on vacation in a different country and be able to adjust your mowing schedule.
Virtual Assistant Compatibility
Some people love having the ability to control different aspects of their life through Amazon Alexa or Google Home. If you use a virtual assistant often, then a robotic mower that’s compatible with your smart speaker can easily integrate into your life.
Some robotic mowers come equipped with a GPS tracking system. This is helpful as an additional security measure; if your mower gets stolen, you might be able to track it down. It is also helpful if you just want to know where your mower is located for whatever reason.
Robot Mower FAQs
How long will my robotic mower last?
The first major part that you will need to replace is your mower’s battery., which will typically last about two to three years. Any other parts, like the blades or wheels, are replaceable, so in theory, your robotic mower could last as long as 20 years. In practice, your new robotic mower should last at least ten years.
How much maintenance will my robotic mower require?
Robotic mowers are low maintenance compared to regular gas lawn mowers. Regularly, all you should need to do is wipe the underside of the mower to keep it clean and be sure that no grass or other debris is caught in the wheels.
You should replace your robotic lawn mower’s blades regularly. The sharper your blades, the more effective your mower will be.
Can I leave my robotic mower out year-round?
While robotic mowers can be left outside in all seasons, if you live somewhere with below-freezing winter temperatures, your mower will last longer if you bring it indoors for the colder months. When temperatures dip in the fall, your grass will stop growing, and at that point, you can store your mower indoors until the growing season begins in the spring.
Whether you have a small yard or a sprawling lawn, a robotic mower can be a simple lawn care solution that gives you time to work on other things or sit back and relax and enjoy your weekend. Although they are expensive, the time and effort that a robotic lawn mower saves you could be well worth it.
Our top 5 picks are a sampling of the best robotic lawn mowers on the market, and we hope one works for you and your lawn.
