Robot Lawn Mower Buying Guide – What to Look For When Buying A Lawn Mower
Before we identify the key features that you should look out for when choosing a robot lawn mower, it’s best first to understand how this lawn-friendly machine works.
How Does a Robot Lawn Mower Work?
The working principle of a robot lawn mower is pretty simple. All robot lawn mowers use rechargeable batteries to operate their motors; hence there’s no need to worry about refueling. Robot lawn mowers also come with an AC-powered base station where it recharges the battery and a perimeter wire.
First, you’ll lay the perimeter wire at the edge of the area you intend to cut. The perimeter wire has a sensor that the mower responds to help it find its way around the lawn without wandering off. You can install the perimeter using ground pegs or by burying it in the ground according to the mower brand’s specification.
Once the mower senses the perimeter wire’s signals, it changes direction to avoid going off your property or damaging delicate landscape features. Robot lawn mowers also have obstacle detectors or collision sensors such that when they bump into an obstacle, they automatically change direction.
Once the mower finishes working or runs out of battery, it automatically returns to the docking station to recharge.
Factors To Consider When Buying a Robot Lawn Mower
Since robot lawn mowers are not precisely what you’ll call “popular,” it’s understandable that most people are unsure of the essential features they must check for before buying them. These features are what we used to compile this list of the best robot lawn mowers.
Mowing Area/Lawn Size
Before buying a robotic mower from the store, you’ll need first to determine the size of the area where you wish to use the mower. A mower’s mowing area refers to the maximum size yard it can mow.
Knowing the mowing area will guide you to choosing the best robotic lawn mower for large areas. Note that the larger the mowing area, the more expensive the robot lawn mower will be.
Typically, residential robot mower models have a mowing area of 0.20 acres to 1.25 acres.
If your property is located in a quiet environment or you have close neighbors, it’s essential to keep them in mind when choosing a robot lawn mower. Fortunately, all lawn mowers use batteries, making them quieter than other lawn mower types like gas mowers. Their noise generally ranges between 60dB to 75dB.
If you intend to use your lawn mower at nighttime, you should get one with the least possible noise level, unless you don’t mind interrupting your sleep and that of your neighbor.
Cutting Width and Height
Your mower’s cutting width determines how much ground it can cover in one pass. Mowers with larger cutting widths will cover much ground at once and finish mowing your lawn faster than one with a small cutting width.
It’s possible to adjust your mower’s cutting height according to your preference. Changing the mower’s cutting deck is as simple as turning the dial or lever accordingly.
Another vital feature to consider in robot lawn mowers is the battery voltage. Robot lawn mowers that have higher battery voltage will generate more power output than those with small battery voltage.
The power output determines how much grass thickness your mower can handle. Hence, a mower with a 26 volts battery will be better for an overgrown lawn than an 18 volts mower.
Robot lawn mowers are generally more expensive than other types of self-propelled or push lawn mowers. Their price usually starts from $1000 and some can cost as much as $4000 or even more. However, the more expensive the mowers are, the more sophisticated they’re likely to be.
Other Special Features
Aside from the basic features we’ve discussed above, here are some additional and more advanced features you may consider. But remember that the more sophisticated the lawn mower is, the more expensive it’ll be.
Most robot mowers have dedicated mobile apps that they connect to via Bluetooth, but it’s impossible to control your machine when you’re not at home because of the range of the connectivity. On the other hand, if your mower has Wi-Fi capability, you can control it from anywhere you are in the world.
Robot mowers usually have an in-built GPS tracking system that helps the mower navigate the lawn more accurately and provides security for the machine. Therefore, if your device gets stolen, it’s easy to track it anywhere in the world and retrieve it.
Security PIN Code
Security PIN codes provide an extra security layer for your machine. Robot mowers that have this feature will only work after you enter the correct security PIN. Hence, the device will not be useful to any thief who decides to steal it.
This feature is helpful if your lawn has a steep slope or rugged terrain. Hence, it’s not common with all robot lawn mowers. However, you can get a premium model with this feature for extra money.
Bottom line- Best Robot Lawn Mower For Your Home
So if you decided to stop wasting time pushing your gas or fuel-powered mower, you can either hire a professional lawn care service or buy a robot lawn mower. We prefer the latter. With the information we’ve covered in this guide, choosing a lawn mower should not be difficult. You can order your choice lawn mower online or visit a local store near you.
