Buyer’s Guide

When shopping for a robotic lawn mower, please consider the following:

• How Robotic Mowers Work
• Battery Voltage
• Mowing Area
• Cutting Width
• Cutting Incline
• Cutting Heights
• Noise Level
• Special Features
• Prices

How Does a Robot Lawn Mower Work?

Having a robot do your yard work for you might sound too good to be true, but how a robot lawn mower works is quite simple; they are similar to robot vacuums. All robot lawn mowers run on rechargeable batteries, so you never have to worry about refueling them. 

How do they find their way around your yard? 

Most models respond to a perimeter wire, much like a dog with a shock collar responds to an invisible pet fence. 

How does the perimeter wire work?

To set up a robotic lawn mower, you install a wire around the area you want the robot to mow. Sometimes you bury the perimeter wire, and sometimes you secure it to the ground with pegs.

The wire sends out a signal, which the mower receives. The mower will turn around when it gets close to the boundary wire. That way, it doesn’t leave your property or damage landscape features like flower beds. 

When do they mow?

Depending on the mower, it might run a pre-set amount of times per week, or you might be able to set up a completely customized mowing schedule.

Either way, when the robot mower is out working and the battery runs low, it will return to the docking station on its own to recharge. This is a standard feature, so you won’t have to worry about it dying in the middle of the lawn. 

Where do the grass clippings go?

Robotic mowers finely mince grass clippings to just a few millimeters. The fine mulch degrades into the soil, fertilizing your lawn. Mulched grass clippings are one of the best lawn fertilizers. They are nitrogen-rich, inspiring dense green grass growth.

Battery Voltage

Most robotic mowers run on lithium-ion batteries. The higher the battery’s voltage, the higher your mower’s power output will be. More power means the mower will be able to take on thicker and longer grass. 

Mowing Area

Please pay attention to the model’s mowing area because this is the maximum yard size it can handle. If your yard is a full acre and you buy a robot mower with a mowing area of ¼ acre, only part of your lawn will get cut.

On the other hand, if your yard is ¼ acre and you buy a mower suited for an acre or more, you’re probably spending a lot more money than you need to. Robotic mowers for smaller lawns tend to cost less than those for larger lawns, as shown in the table below.

Max Yard Size	Average Price
< ¼ acre	$1,000
¼ acre	$1,135
½ acre	$1,300
1 acre	2,250

Cutting Width

Like with any other lawn mower, the cutting width (the size of the cutting deck) tells you how much ground a robot mower will be able to cover in one pass. Mowers with larger cutting widths finish mowing quicker.

Of course, the speed of the job doesn’t matter as much with a robot lawn mower as it does with other mowers; you won’t be doing any of the work yourself. However, mowers with larger cutting widths tend to handle larger yards. On the flip side, smaller mowers fit better through narrow passages.

The table below shows robotic mowers’ typical max yard size by cutting width. 

Cutting Width	Typical Max Yard Size
< 8 in.	⅓  acre or less
8 – 9 in.	¼ – ½  acre
10+ in.	¾ – 1 ¼ acres

Cutting Incline

A robotic lawn mower’s maximum cutting incline is how steep of a slope it can climb. If you have any incline in your yard, make sure you know its slope so you can choose a robot mower that will be able to climb it.

We measured the slope in degrees, but you’ll find that some product pages give a percentage instead. You can easily convert the percentages to degrees with an online calculator.

Cutting Heights

Lawn mowers have multiple cutting height adjustments, so you can choose how tall you want your grass. However, some mowers have a wider cutting height range than others.

The table below shows ideal mowing heights for common turfgrasses. You want a mower that manicures your lawn to the perfect height.

Grass Type	Ideal Mow Height
Bahiagrass	3 – 4 in.
Bentgrass	0.25 – 1 in.
Bermudagrass	0.5 – 1.5 in.
Buffalograss	2 – 4 in.
Centipedegrass	1 – 2 in.
Fine Fescue	1 – 3 in.
Kentucky Bluegrass	2 – 3 in.
Perennial Ryegrass	1 – 3 in.
St. Augustinegrass	2 – 4 in.
Tall Fescue	2 – 4 in.
Zoysiagrass	1 – 2.5 in.

Noise Level

If you live close to your neighbors, you probably don’t want to burden them with a noisy machine. The good news is that all robotic lawn mowers are battery-powered, thus much quieter than gas mowers.

While gas lawn mowers tend to produce about 90 decibels (dB) of sound, most robot mowers produce 60 to 75 dB. 

Special Features

It’s fine to focus on the mower’s main specs, but don’t forget to consider these special features:

• GPS tracking: GPS in a robotic mower serves a few purposes. It can help the mower navigate your lawn more accurately, but it’s also helpful for security. If someone steals your mower, you can track it down quickly.

• All-wheel drive: All-wheel drive isn’t common in robot mowers. If your yard has a lot of rugged terrain, steep slopes, or other complications, you might need to spend a little extra for a machine with all-wheel drive. 

• Wi-Fi connectivity: When a mower connects to Wi-Fi, you’ll usually be able to access it from anywhere in the world. However, you may be able to buy an extra attachment to connect to the Internet even if a mower doesn’t come with it. 

• Virtual assistant compatibility: Some robot mowers can connect to “smart home” virtual assistant systems such as Amazon Alexa or Google Home. With this feature, you can give a voice command like “Alexa, mow the lawn”.

• Security PIN code: For extra security, some robot lawn mowers only run after you’ve entered a PIN. It’s like unlocking your phone with a passcode. Just like a thief can’t use your phone without the passcode, he won’t be able to use your mower without the PIN. 

Price

Most robotic lawn mowers cost $700 to $2,650 and the models on our best robotic lawn mower list cost $1,000 to $2,650. Robotic mowers cost significantly more than a standard push mower but less than many of the best lawn mowers for large lawns.

Average Cost of Robotic Mowers	$1,500
Typical Price Range of Robotic Mowers	$700 – $2,650
Average Cost of the Best Robotic Mowers	$1,845
Price Range of the Best Robotic Mower	$1,000 – $2,650

For comparison, most push lawn mowers cost $115 to $370, while the best push mowers cost $90 to $575. Most self-propelled lawn mowers cost $450 to $1,500, and a typical lawn tractor costs $1,350 to $4,000. The best zero-turn mowers are the most expensive, costing about $4,000 to $6,100.

FAQs About Robot Lawn Mowers

1. How long do robot lawn mowers last?

It’s hard to know how long robot lawn mowers last since modern ones have only been around for a few years. With proper maintenance, there’s no reason a robot mower shouldn’t last for ten years or more.

The batteries will go out much sooner, though, and you’ll probably have to buy replacements every two to three years.

2. What maintenance does a robot lawn mower need?

You want to keep your robotic mower clean with sharp blades:

• Cleaning: Like other lawn mowers, you’ll need to clean the underside of your robot mower regularly. Ensure that grass clippings, caked-on dirt, and other debris don’t build up around the wheels and other moving parts. Improper cleaning can slow down your mower or cause malfunction. 

• Blades: You’ll also need to replace the blades regularly for maximum cutting performance. How often you replace them will depend on the specific model. 

3. What are the best cordless electric lawn care tools?

If you’re sick of smelling gas fumes, you can try using cordless electric lawn care tools. Here are some of the best ones:

• Leaf Vacuum: The best cordless leaf vacuum is the Ryobi RY404150.

• Leaf Blower: The best cordless electric leaf blower is the Ego Power+ LB7654.

• Hedge Trimmer: The best cordless electric hedge trimmer is the EGO Power+ HT2400.

• String Trimmer: The best cordless electric string trimmer is the WORX WG191.

• Lawn mowers: Robotic models aren’t the only cordless electric mowers. If robotic mowers are outside your price range or too new-fangled for your taste, you can take a look at the best battery-powered lawn mowers.
