How Much Does A Robotic Lawn Mower Cost?

In this post we evaluate how much does a robotic lawn mower cost

Having a beautiful garden is an amazing thing, to look out and see a well-cut lawn is a real treat and makes you feel great about what you’ve done. But unless you’ve got tons of time or the money to hire a landscaper, you’re stuck cutting that grass yourself. This can take hours, depending on the size of your yard.

So, how much does a robotic lawn mower cost?

The robot lawn mower itself will cost between $1000 – $3000, depending on the brand and model. Then there is the installation. You can expect to pay around $300 if you don’t want to do it yourself. Wire fence boundaries will be around $150 – $200 and an optional garage about $95. On top of that, you mush consider insurance, replacing batteries every 2-3 years, cleaning equipment and replacement blades.

Based on the above you can expect a robot mower to be around $500 on top of your initial purchase cost. But you can save a lot of that if you are willing to do the installation yourself.

So is it worth it? Of course, it is. Keep on reading and we’ll break it all down for you.

Interested in a robotic lawn mower?

Given that many of us have kids, spouses, hobbies, and other obligations, it is not feasible to think we can spend hours on one task alone. And you might only have time to mow early in the morning due to time or heat restraints, but waking the neighbours is a huge no-no and quite rude. The solution? 

Get yourself a robot lawnmower. These are quiet machines that can do a pretty good job, and you can let them do the work while you do other things. They are kind of like those robot vacuums if you have a basic understanding of how those work, you will easily understand how the lawn mowers work. 

In this article, we are going to answer how much does a robotic lawn mower cost and discuss all the ins and out of robotic lawnmowers: the purchase, the price of maintaining one, fuel costs, and more.

This is your inside look at what you will be looking at if you choose to pick up one of these helpful robots. 

Part 1: The cost of a robotic lawn mower?

For the lawnmower itself, you are looking at anywhere from $1000 to 3000 and up. 

But why is this?

It’s all about what these helpful robotic lawnmowers feature that makes them so expensive. You might say it is their helpful technology that makes them a bit of a pricey venture. 

Let’s take a look at three of the top-selling robot vacuums and what makes them so special. 

Our top three robotic lawn mowers

Be sure to check out our complete list of the best robotic lawnmowers, but for this post, we thought we highlight three of our favorite models.

Husqvarna Automower 315X

Husqvarna AUTOMOWER 315X Robotic Lawn Mower

With the Husqvarna Automower 315X, you can use your voice to cut the grass. You can manage the schedule of when your lawnmower is to cut the grass and keep track of the exact location of the mower by using the Automower Connect app. You can use your voice to start or stop the lawnmower using your smart speaker-it is Google Home or Amazon Alexa compatible.

This mower runs by using boundary wire to stay in its rightful zone and is easily able to manoeuvre around objects in the yard like kids’ toys and trampolines/ lawn ornaments. 

The machine is quiet enough to run at night, and there are absolutely no fumes or noise associated with running the machine.

Husqvarna AUTOMOWER 315X Robotic Lawn Mower

You can run this robot in the rain, and the clippings this robot creates are absolutely fine to simply leave on your yard as a natural fertiliser. You don’t have to rake up and bag lawn clippings!

One thing we would like to put out there before you buy the mower is to consider going through a local Husqvarna dealer. Some users on Amazon complained that they were not able to access their mower unless they were given a PIN, which they did not get when buying through While Amazon is a great website, we advise that for a purchase this large, it may be best to talk with a local dealer about this particular mower. 

Worx Landroid M 20V WR140 Robotic Mower

WORX WR140 Landroid M 20V Robotic Lawn Mower

The Worx Landroid M 20V WR140 can mow up to a quarter of an acre and is a fully automated robot lawn mower that is pretty smart and capable of learning about the yard you have. It then takes what it has learned to create a schedule based upon the size of the yard. It is quite easy to install, and the setup can be done in a matter of minutes.

This mower cuts just a little at a time, so patience is required. It naturally fertilizes your yard thanks to the grass clippings it creates.  You can use the mobile app right on your phone or tablet to get the mower out and control it, no matter where you are. 

One thing we really liked about this particular mower was the “Find My Landroid” feature. In the event that your Landroid robot lawnmower leaves the perimeter, you can always find out where it went thanks to the device being connected at all times. 

WORX WR140 Landroid M 20V Robotic Lawn Mower

Precision is the name of the game for this particular mower, and it features the ability to “Cut To The Edge.” You can mow close to the edge of the lawn as compared to other robot lawn mowers, meaning less time you will have to spend with your weed eater. 

And, this great device is weather resistant. If the device senses rain, it will go to its charging base until the rain is gone. The battery is interchangeable with other WORX tools, too.

Gardena 4069 Robotic Lawn Mower

Gardena 4069 R80Li Robotic Lawnmower

The Gardena 4069 is a robot lawnmower that features .7″ to 2″ cutting height. You can simply use a rotary knob to set the height. This particular robot vacuum does not have an app to control it, but you can absolutely set the mowing times and days easily by making use of the generously sized panel and display on the front of the unit. 

This device will work during the rain, and produces pretty good results! The device also comes with anti-theft protection and is low noise. You can run it at night or early in the morning, and you will have no worries about waking up the neighbours or bothering other people. This is also a great way to control emissions – it’s completely emission-free. 

All you need to set up this mower is a pair of wire cutters, some pliers, and a hammer. The device comes with all you need to set it up and can be performed on your own. (It will be critical to read the manual and follow all steps for setup, however).

After that, setting up the grass cutter is easy. Just use the display to program it the way you want, set it up, and allow it to go over your lawn. You will find the grass to be neatly trimmed and looking great. 

Largely, the only major “con” with this device is the lack of app, but given its ease of use, it still comes in as a huge winner.

Setup Costs

The biggest cost of setup is going to be putting in the low voltage wire around the outside of your lawn. This is used to create what some might call “an invisible fence.” 

If you already have a fenced-in yard – many of us do thanks to having dogs or kids-you probably don’t need to worry about this. 

However, some of us may want to fence off areas of the yard that don’t need to be mowed, such as a garden or flower patches. 

So, the question is: Is this an actual fence I am putting up? Absolutely not. You will be installing a boundary wire like this one, and your cost will vary based upon the amount of wire you need. 

Some of you are going to need the full 2000 feet, which costs $160 and that’s OK. Some of you may just need 500 feet to block off some spots around the house, and that’s fine-it costs $80.00. There are different price points in between, too. 

The reason we chose this particular brand is that: 

  • It is protected, solid core boundary wire rated at 14 AWG
  • It’s universal and will work with any brand or model of an automatic lawnmower
  • You can install it above ground or bury it up to 18 inches below the surface.
  • The wire is designed to last 20 years including through the rain, snow and all other weather
  • It’s made in the USA
  • You can buy it in varying lengths
  • It is unobtrusive

More often than not, the 20 gauge wire that comes with your robotic lawn mower will wear out faster than this. Some users find this helpful to just buy right along with their robotic lawnmower, as it is crafted with a thick and protective 45 mil polyethylene jacket and is resistant to UV rays.

It is simple to install, too – yard staples placed at 5 feet intervals will keep it in place.

Maintenance Costs

As with any power tool, you will need to perform basic maintenance tasks to ensure your investment stays as helpful as the day you bought it. 

When answering how much does a robotic lawn mower cost, we have to talk about the maintenance costs associated with owning one. 


To clean your robot lawnmower, it is advised you use a bristle brush and some shop towels to clean off the excess grass that builds upon the wheels and underneath. (Side note: Always make sure when cleaning that you turn off the master switch so that the vacuum does not turn on. Some of these mowers turn off when lifted up, but it’s best to be safe).

Another side note: Some people think it may be a good idea to spray down the mower with a hose to clean it. After all, it’s safe in the rain, right? Not so. These mowers are often rated for water resistance but are not waterPROOF. Therefore, do your cleaning tasks by using brushes and shop towels. 

Replacement Blades

You can buy universal replacement blades, or you can buy ones that are specific to your brand. For example, Husqvarna makes replacement blades readily available that retail for around $65 per 45 blades.

You can also buy blades designed to fit other robot lawn mowers, for example, these ones we found are much cheaper than a branded option. The recommendation is to replace your blades on a monthly basis.


The batteries you get in these robotic lawn mowers are Lithium-Ion, which have a lifespan of about 2-3 years or 300 to 500 charges. Your battery will vary and could last longer or shorter.

When it comes time for you to replace your own battery, you could be looking in the region of $50 based upon our findings of the WORX batteries for sale. Pricing will vary from brand to brand, but this gives you an idea of what to expect. 

Garage for Robot Lawn Mower

If you choose to keep your robot outside, you may wish to purchase a little “garage” or cover for the tool. These look stylish and cool and provide a place for your robot to store neatly while you wait to use it again.

They do come at a cost, however, and many of us will probably opt to store our robots in the shed or take them to the garage. But if you like, a wide range of covers are available and they average at about $100.


Of course, in a perfect world, your mower will never break or be stolen, however, we would be fools to not consider the fact that it could be.

Many household insurance policies do not cover a mower unless it’s locked in a garage, which completely defeats the purpose, so it is certainly worth checking with your provider if it would be covered under your current insurance. If it is not, then maybe chose a policy that does.

Other Indirect Costs

  • Electricity: You will have to charge your robot lawn mower after you are done using it. This will increase your electricity usage, and thus drive up the bill you pay each month for electricity. This cost cannot be determined here as the pricing of electricity varies from state to state. The good news is that we can infer from some users that the cost will not be much at all. This Youtube video by a happy Husqvarna user noted that it cost only 5 cents to charge their mower based upon their electricity company’s cost.  

Part 2: What Are the Negative Points About Robotic Lawn Mowers?

Sure, owning a robotic lawnmower has its downsides. Nothing is perfect, so let’s talk about three of the major disadvantages associated with owning a robotic lawnmower. 

You fear somebody could steal it

Many of these have a “find my robot” feature, where you can see where the device went if it goes off the perimeter, but this could lead you to some unsavory places where you’d rather not risk getting your robot lawnmower back. As a result, it may be best to just operate these when you are at home and able to oversee the operation yourself.

The lack of stripes

Perfectionists everywhere love the beautiful and satisfying stripes that appear on the lawn after it has been mowed by yourself or a professional. The robot takes a random path everywhere, so the lack of stripes can really make some people feel like their yard isn’t up to standard. 

It’s pricey

The luxury of having a robot lawnmower will cost you. From base cost to accessories and replacement parts, this is not a cheap venture at all. See our price bottom line at the end of the article. But then again, you will be saving a lot of time.

It Can be hard to use elsewhere

You might have ideas of taking this robot to a family member’s house and cutting their grass. But, if the yard is not fenced off or fitted with the “invisible fence,” you run the risk of having the robot go all over the yard and possibly get lost.

They don’t cut everything

The robot lawnmower is definitely a big help, but it is not going to cut each and every little thing that ends up in your yard. Some users noted that the robots would stop or get stuck on certain weeds in their yard, so be prepared to lend a helping hand to your lawnmower in the event that it gets stuck while working. 

Part 3: Additional Questions and Answers

Do Robotic Lawn Mowers Work? 

These robotic lawnmowers work best when they are utilized a few times each week and are tasked with trimming a little bit of the lawn each time.

By doing it this way, the grass clippings are small enough to sink back into the ground instead of sitting in the sun and turning into brown, crispy grass. 

And yes, they also work on sloped yards, too. The robots work by taking random paths around the yard, similar to how a Shark Ion Robot Vacuum or Roomba operates.

The fact that they do not generate the satisfying parallel lines as humans do is somewhat bothersome but still gets the job done. Some people still find themselves heading outdoors to do touch-ups after their robot vacuum has parked itself.
