Owing a home with a nice yard is a dream come true for millions of families worldwide.

After a while though, keeping our lawns maintained becomes just another tedious chore and one we often put off for a week or two until we can no longer look at our overgrown yards. Unfortunately, when we let our grass get to the over grown stage, it becomes more difficult and time consuming to mow which in turn gives us the uneasy feeling of dread when we just think of having to do it all again next week, or the week after.
To save you from this weekend misery, we’ve looked at some of the best robot lawn mowers with a variety of features that will keep your lawn looking permanently immaculate so you can free up your precious time on the weekends and pursue more enjoyable activities like hiking with your family, going fishing or soaking up some sunshine as you relax at home while your lawn looks like it is being maintained by a whole crew of gardeners.
The Best Robot Lawn Mower
We’ve already featured a couple of Husqvarna robot lawn mowers on this list. They’re getting a reputation for being some of the most efficient, connectable, and easy-to-use robot lawn mowers on the market. The Husqvarna Automower 310 sits nicely in the middle of their range, designed for yards a quarter of an acre or smaller. It can also work on slopes up to 22º, which is impressive for a robotic lawnmower at this price.
Like all robot lawnmowers, it’s guided by hidden boundary wires. This mower knows how to navigate within the space and automatically returns home when it needs charging. You can control it using the [email protected] app, which allows you to set and adjust until your mower’s schedule is perfect. The Bluetooth connectivity works up to 100-feet. Plus, it’s quiet enough to run at night, so you don’t have to worry about waking your neighbors up.

One of the drawbacks of owning a machine (any machine) is the number of hoops you have to jump through to get it working. Some devices come with manuals, but these are sometimes difficult to understand, meaning that you take a long time setting it up and could even give up in frustration halfway through. This is an experience you will never have to face with the WORX WR140 Landroid M 20V Robotic Lawn Mower, which doesn’t present you with hoops to jump through. The mower is easy to set up with convenient steps laid out for you to get it up and running, and once you do this, there is no turning back. This super-smart robot lawnmower can learn about your lawn and will, after some time, suggest optimal schedules based on the size of your yard.
Additionally, the WORX WR140 Landroid lawn mower can cut up to ¼ of an acre, and with its steady work rate, it ensures that naturally fertilizes your land. If you are unsatisfied with the recommended mowing schedule set out by mower, you can always adjust it to your liking with the help of the mobile app, which is easy and convenient to use. Not only that, the app allows you to control the robot mower to do your bidding remotely. Beyond that, it also comes with a cut to edge feature that enables the device to cut closer to your lawn’s border, which, in turn, leaves you with very little work to do once the mower is done with the yard. Robot lawnmowers aren’t cheap, which is why the security feature on the WORX WR140 Landroid M is so appealing. It contains a ‘find my Landroid’ module that alerts you as to when the machine is leaving its designated area in cases of theft.

The Robomow RX20 is one of the best-loved robot lawn mowers on the market. It’s the mid-range option in Robomow’s RX range, which means it doesn’t have all of the same premium features as the really high-end models, but we still think it’s one of the best options on the market.

Thanks to its smart navigation system and small seven-inch cutting width, it can fit down narrow paths, negotiate tree stumps, and much more.

Robot Lawn Mower Buying Guide and FAQs
How We Chose Our Selection of Robot Lawn Mowers
Quality - The best robotic lawn mower is one that is built to last. Yard work is hard work so we looked at mowers that are robust and can handle continuous use over lengthy periods. A good quality mower will see your lawn neat and tidy for many years, especially if you check it from time to time and change the blades when necessary.
Reviews - We checked the robotic lawn mower reviews on dozens of sites in our search of the best models so you don't have too. Word of mouth has always been an effective tool for consumers and now, thanks to the internet, we can get a much broader insight into the products we want to buy. There is no better way to check a products reliably than to read the reviews of people who already have some experience with the product.
Brand - We stayed away from cheap and inferior imitations and looked at the brands that have an international reputation of producing superior quality machines. The brands in our guide are reliable and known for thorough quality control.
Price - The average battery powered lawn mower is not exactly cheap but even so, we checked the best models in a variety of price ranges. The price varies depending on things like warranty periods, special features and the size of the yard it is capable of mowing. At the end of the day, it is better to pay a little more for a reliable quality machine to avoid frequent repairs and replacements in the future.
Features To Look For In Robot Lawn Mower
Ease-of-Use - The initial set up of your battery powered lawn mower may take a bit of time because you will either need to install a boundary or perimeter wire, or configure your property's boundary into the mower's GPS navigation. But once you do this, you really want to be able to sit back and relax with minimal effort required on your part. We chose models that require a little bit of work in setting up when you first bring your mower home, but then you want to let the mower do its job while you only check on it once in a while.
Quality of Cut - This is the whole purpose of purchasing any lawn mower but in particular with robot lawn mowers, you want a model that shreds the grass cuttings into fine particles that stay on the ground and act as a natural fertilizer that will promote a lusher greener lawn. You definitely don't want to have to run after your mower to rake up the cuttings. Furthermore, you want a uniform cut of your lawn so that it looks impeccable all the time.
Slope - Okay, so your automatic lawn mower will not climb mountains, but if you live on a larger property, chances are you don't have a completely flat yard. While most automatic mowers can handle slight inclines or slopes it's still a good idea to check for a model of lawn mower that can handle any slope or incline you have on your property to make sure it will do the job right for your whole yard.
Smart Perimeter Control - Depending on the brand and model of robotic lawn mower you choose to buy, your mower will either have GPS so you will be able to program the mower to only mow the lawn within the boundary of your yard, or your mower will come with a perimeter sensitive wire that you will place around your yard and secure with pegs or staples. Either way, you can be sure that your mower will not be crossing into your neighbour's territory.
Safety - Kids are naturally curious and it only takes a second of distraction and you will miss seeing them getting into all sorts of trouble, and animals may want to attack this foreign intruder that is running around the yard. While it's always best to keep the kids and pets away from any type of mower, the best robot lawn mower should have a safety feature that automatically stops the blades from spinning the moment the mower is picked up or flipped over.
Price - It's always natural to want to save money but at the end of the day, you get what you pay for. The old-fashioned mower is a lot cheaper, but it involves you pushing it to get the mowing done. The cost of your robotic lawn mower will depend on the size of your yard, the type of grass you have and the features you want or need. Of course, your budget is also an important consideration too. It's simple economics to decide what you are prepared to pay and also get as many of the features you want.
Robot Lawn Mower FAQs
Q: What is a Robot Lawn Mower?
A: The simplest way to describe a robot lawn mower is that it is an autonomous robot that has been specifically designed to mow your lawn. All it takes is a little bit of programming and the robotic lawn mower will automatically and periodically do the rest of the hard work for you.
Q: How Often Should I Use a Robotic Lawn Mower?
A: How often you use your robotic lawn mower will depend on many factors. The first one being the type of grass you have and the height you prefer your grass to be. Keep in mind that some types of grass grow faster than others and all grasses will most definitely grow a little faster over the warmer months of the year. You can program a schedule into your mower and it will automatically set out to work accordingly, but many mowers also come with an override feature so you can get it working if your grass needs an earlier mowing. Some manufacturers recommend allowing your mower to do its job everyday as this will keep your grass at a consistent height making it easier to maintain and looking pristine every day of the week.
Q: Can I Use a Robot Lawn Mower While It Rains?
A: Some models of robot lawn mower work perfectly well in all weather conditions and that includes rain. This is a must have feature if you live in an area known for its frequent showers. Fortunately, even if your mower isn't compatible for wet weather mowing, it should still come with a sensor that will send it back to its base when it detects rain. The convenience of this is that either way, you don't necessarily need to sit around at home to keep an eye on your mower.
Q: Do I need to Buy Any Accessories For My Robotic Mower?
A: Some makes and models of robotic mower come with everything you need to set up and install your mower and get it working immediately. Other models require some accessories to be purchased such as the perimeter wire and staples. Check the specifications to see what, if any, accessories will be necessary to be purchased before you decide which mower you want to buy.
Q: Can I Control Robot Lawn Mower Remotely?
A: Smart technology is everywhere these days. We can operate and control so many of our modern conveniences using our smartphones like the heating in our homes or opening garage doors before we get home. Some brands and models of robot lawn mower also take advantage of this technology so you can control your mower remotely with the use of your smartphone. This would be a particularly useful feature if you are at work, on vacation or simply not at home while your mower is in operation.
Q: How Long Do Robotic Lawn Mower Batteries Last?
A: Once the robotic lawn mower batteries are fully charged they should be able to mow your lawn for anything from 60 to 90 minutes. Some models may even have a longer mowing time. This, of course, depends on the mower you have, the type of grass you have and how level your grounds are. In terms of the life expectancy of the batteries, they average about 2 years. The factors that determine the batteries life are the size and type of yard you have, frequency of use, and the type of mower you own.
Q: Does a Robot Recognise Obstacles and Objects On the Lawn?
A: Most of the newer robot mowers have sensors that recognise or detect obstacles and objects on the lawn and will, in most cases, simply go around them. However, some smaller objects, like small branches or fruit from trees, etc., may not be detected and the mower will simply mow over them. While this is not a problem for the mower, if you have harder objects like branches or pine cones that frequently fall on your lawn, it's a good idea to rake them up and remove them before the mower is in motion. Again, it's not such a big problem for the mower, but it could result in you needing to change the blades with a little more frequency.
Q: If I Don't Have a Fence, How Will a Robotic Lawn Mower "Know" Where the Edges of My Yard Are?
A: The perimeter control features of a robotic lawn mower will keep your mower working only in your yard. Depending on the make and model of your mower, it will either come with GPS technology that will be programmed into your mower so it "knows" when to stop at your property's boundary or, your mower will come with a perimeter wire which will send a signal to your mower to not go any further. If you decide to share your robot mower with a neighbour or family member, keep in mind that you will need to change the coordinates if you have a mower with GPS, but it's a lot more complicated and inconvenient if your mower uses a perimeter wire to control its movement.
