6 Benefits of a Robotic Lawn Mower

Pushing a lawn mower, even a self-propelled one, can be tedious, time-consuming work. But what if the mower pushed itself? Think Roomba for your yard. In this article, we’ll introduce you to the five benefits of a robotic lawn mower as an alternative to traditional push or riding mowers.

In this article, we will cover the six reasons to switch to a robot lawn mower:

  1. They’re convenient
  2. They cut consistently and efficiently
  3. They are better for the environment
  4. They are quiet
  5. They promote a healthy lawn
  6. They require little maintenance

1. Robot lawn mowers are convenient

Importantly, robotic lawn mowers don’t cut into your free time. They operate at night, or while you’re at work. You set the mowing schedule. Besides the occasional edging, you won’t need to spend any time worrying about the state of your grass so you can spend more time entertaining or relaxing outdoors.

The initial installation will likely take the better part of a day, but once everything is set up, your mower is almost entirely self-sufficient. Simply select the mowing schedule you wish on the onboard control panel and it will handle the rest. Many mowers connect to your home WiFi or use a Bluetooth signal, allowing you to program and control them from your mobile device. This lets you set your mowing hours and weather protocols with almost no effort at all.

Because the mower makes frequent, shallow cuts, your robot will maintain a consistent cutting height throughout your turf’s growing season.

2. Robotic mowers cut efficiently

Yes, robotic mowers really work. Grass grows at different rates, depending upon the nutrient content in different areas of your lawn. Mowing just once a week can lead to inconsistent patches of thick and sparse growth, especially during the warmer months. A robot mower gives you that clean, even look by mowing more frequently.

Many autonomous mowers have an automatic spiral-cut feature that identifies thicker patches and dedicates extra mowing time to that area. This keeps your grass even and presentable all week long.

Consistency is key when it comes to keeping your lawn looking great. The random mowing pattern of a robot mower is designed to cover the whole lawn without leaving streaks or tire marks from following a set path. There’s no easier way to cut grass evenly than by trusting your lawn’s care to a robot.

3. Robo mowers are better for the environment

Like all other electric tools, robotic mowers are an eco-friendly way to cut grass. Gasoline-powered mowers present a range of problems that are solved by going electric. The emissions from gas-powered tools contribute to atmospheric carbon buildup and are harmful when breathed in. Leaks and condensation can pollute your lawn and your local watershed.

Electric mowers present an eco-friendly alternative to gas tools. While they aren’t always carbon-neutral (the electricity from your home still has a carbon footprint), they greatly reduce the environmental impact on your lawn and its immediate vicinity.

Electric motors, such as those found in robotic mowers, are also far easier to operate than their gas cousins. Engine maintenance is a thing of the past – no burning fuel means no residue or buildup. Starting a robotic mower takes a simple button press; gas engines require an air purge, choke, and cord pull to get up and running. And they are cordless, unlike many of their electric push mower cousins.

Whether or not you’re planning to switch to a robotic model, electric mowers are a much healthier and greener alternative to gas tools.

4. Robot mowers are quiet

Robotic mowers have another advantage over traditional lawn mowers. Their smaller cutting decks and lightweight razor blades require less motor power than full-size electric mowers and allow them to operate virtually silently. Some models, like the Gardena Sileno series, operate with as few as 56 decibels of sound output, quieter than a window-unit air conditioner.

Because you don’t have to worry about disturbing the neighbors, you can let your robo-mower run at night without losing sleep. For homeowners that want a beautifully manicured lawn without ever having to see or hear the mower, this option is invaluable. Most autonomous mowers come with built-in anti-theft features, so you can sleep soundly while your mechanical mower pulls a graveyard shift.

5. Robotic lawn mowers promote a healthy lawn

Many lawn mowers on the market include a mulching option. Whether included or available as an optional kit, mulching systems are a great way to reuse the grass clippings generated by mowing. Mulching mowers use airflow to keep the clippings airborne inside the cutting deck for a long enough time that the cutting blades slice them into fine particles.

Because robots work more frequently than traditional mowers, they cut smaller clippings. The small, lightweight razor blades on a robotic mower are sharper and spin faster, resulting in powdered clippings that are finer than most traditional mulching mowers.

Mulching your grass clippings can benefit your yard’s health greatly. Leaving full-sized grass clippings in your yard contributes to thatch buildup, a layer of dead grass that sits atop the soil and can prevent nutrients from sinking in. Finely mulched grass returns the nutrients from the blade tips to the soil, seeping in with the rain to deliver valuable nitrates directly to the roots.

6. Robo mowers require little maintenance

There is no oil to change, no gas to refill, there are no plugs to replace. In short, robot mowers require little maintenance: Hose off the undercarriage occasionally, change the blades once or twice a year and replace the battery every 2-4 years, and you should get 10-plus years out of your unit, and perhaps as much as 20 years. 

Because of the robot mower’s convenience and utility, traditional push mowers may soon become extinct on smaller urban and suburban lawns. One important caveat: Robotic lawn mowers are still limited by the size of your lawn. Some models, like the Husqvarna 450XH, can handle yards well over an acre, but that extra capability comes with a higher price tag. The vast majority of robotic mowers are designed to cut between a quarter acre and half acre of grass.

FAQ about robotic lawn mowers

1. How does a robotic lawn mower work?

Though it’s been improved upon considerably since, the basic technology that powers a modern robot mower was invented in the late 1960s. Most mowers are guided by a lightly electrified perimeter wire that marks the mowable area. The mower cuts often in random patterns to create consistent streak-free grass. Modern mowers will use an algorithm or GPS tracking to create a digital map of your yard to ensure complete coverage.

2. What is the best robot mower to buy?

Lawn Love’s independent research has shown that the WORX WR155 Landroid L has the best-value mower available today. If price is no object, the most advanced mower is the Husqvarna Automower 450XH.

3. How much does a robotic lawn mower cost?

Mowing robots aren’t cheap, but some are more affordable than you might think. The main factor in a robot’s price tends to be the size of the lawn you plan to mow. Robots that mow between a quarter acre and a half acre tend to run between $1,000 and $1,500. Small urban and suburban lawns, especially those around 5,000 square feet, can find adequate robo-mowers for well under $1,000.

4. Does a robot mower really eliminate all yard work?

While you’ll certainly see a drastic reduction in the amount of time you spend thinking about your lawn, a robot won’t perform every task you need. You’ll likely need to go out every once in a while with a string trimmer to clean up the edges, especially along fences and walls. Some robots, namely the WORX Landroids, have a cut-to-edge feature that reduces or eliminates the need for extra weed wacking.

If you’re still not sold on the idea of robots, you can still take the hassle out of maintaining a beautiful lawn. Lawn Love pros are always on-call to deliver gorgeously manicured lawns at affordable prices. Until there’s a robot built for tree-trimming, leaf-raking, or weed control, nothing can beat a professional touch.
