Having a fresh, luscious lawn is a great luxury, but one that’s pretty time-consuming. Robot lawn mowers can be a wise investment for anyone wanting the benefits of grass without sacrificing hours of their lives keeping it trimmed.

Why should I get a robot lawn mower?

Robot lawn mowers aren’t cheap, but they can actually save some cash in the long run. Standard gas-powered mowers need to be refilled, naturally, and even if you go with a manual electric, you might sometimes be tempted to hire someone to save labor — whether it’s your kid or someone from Taskrabbit. 

Robot lawn mowers free up time

According to the Bureau of Labor Statistics, Americans spend about 0.19 hours per day performing lawn and gardening tasks. That’s about 11.4 minutes, or 69.35 hours per year. I don’t know about you, but I could do a lot in nearly 70 hours. So enjoy your day, spend time with the family, take on a new hobby, or focus on your job. Chances are you can make quite a bit of money if you work those 70 hours.

Robot lawn mowers save the world!

We’re exaggerating a little bit here, obviously. You can’t save the world with a robot lawn mower, but you will be helping a bit. Robot lawn mowers are uniformly electric, which means no emissions.

Gas-powered mowers are not only worse for the environment than electric ones, they’re also worse than many other thing using gas engines. According to EPA statistics, operating a traditional lawn mower for one hour produces as much pollution as 11 cars (each driven for the same duration).

Bragging rights

You can’t deny robot lawn mowers are pretty cool to have around. They’re a great conversation starter, and your visitors will be jealous when they see them in action.

Being one with nature

While an autonomous mower saves plenty of time and keeps your grass looking neat, it might also keep you indoors. There are plenty of psychological and health benefits from yard work. If you feel botanical chores are improving your life, you might be better off staying manual.

Tech can still help you improve your gardening, though! There are plenty of apps for that. Check the link below to get some great resources.

High starting prices

The upfront cost of robot lawn mowers is painful. It may indeed save you money in the long run, but a single mower can set you back hundreds (or thousands) of dollars. For many people, that can be an insurmountable barrier.

The cut

The cutting quality of a robot mower must be as good (or at least, nearly as good) as a traditional one to be viable. Furthermore, some types of grass are better cut at certain heights. Even if it doesn’t affect your lawn, you might have preferences. Make sure a mower meets your grass height needs.

Battery life

Do you have a tiny lawn, or acres of grass? Battery life is an extremely important factor. If a mower can’t cover the full extent of your lawn in a single charge, you’ll need multiple cutting sessions, which might mean setting multiple boundaries or moving them around.

Setting boundaries

All robot lawn mowers have a system for setting boundaries, i.e. where they can travel. Some are buried, others placed above ground.

Some mowers have additional sensors that help them dodge obstacles and avoid dangerous situations. You might want to look at models smart enough to learn their terrain.

Do robot lawn mowers return to charging stations?

Not every mower is equipped to charge itself like a Roomba. Do you mind plugging in after every mowing session? You should also consider how long it takes to charge a battery, though this is more an issue if you can’t cover the whole lawn in a single go.

Can it handle the weather?

Your mower will likely live outdoors, so it has to be rugged. Does it rain much where you live? There’s not much point to an expensive robot if it breaks down in a rainstorm.

Robot lawn mower noise pollution

As with manual mowers, some robot models are noisier than others. You’ll want to consider sound levels if the neighbors might complain. Regardless, avoid running your robot late at night or early in the morning.


Mower blades are dangerous and potentially lethal. Most robot mowers should have protection and auto shut-off functions, but some aren’t as smart, and you’ll want to ignore those models if you have kids or pets.

What about the hills?

Depending on your lawn, this can be a huge factor. There’s a difference between mowing a straight patch and battling through slopes. Some robot mowers can handle steeper inclines than others.

Ideal robot lawn mowers can be programmed and do everything on their own. Others may require a little help, which is acceptable, but they should never be confusing. You don’t want to spend precious time just trying to decipher a machine.

Bang for the buck

Pricing depends on multiple factors, such as brand, build quality, ruggedness, features, battery life, and power.

The cheapest robot lawn mowers start around $800, sometimes less. The most expensive ones can lay waste to your bank account, topping $4,000.

1. Robomow RX20

Robomow RX20

No robot lawn mower is cheap, but this is one of the best in the “budget” range. It’s good for a 2,800 square foot yard, and can handle 8.5-degree inclines. It even works with Amazon Alexa, and will automatically return to its dock when it senses rain.

2. Worx WR155 Landroid L

Worx WR155 Landroid L

Pay more and you’ll be rewarded with significantly better specs. The Worx WR155 Landroid L can handle up to a half-acre. It can be controlled remotely through a mobile app, and supports both Bluetooth and Wi-Fi. It can navigate narrow paths, and handles uneven terrain via a floating blade system.

3. Gardena 15101-41 Sileno Life

The Gardena 15101-41 Sileno Life can handle lawns up to 8,100sqft,  charging in 60 minutes for a 65-minute runtime. Bluetooth connectivity makes it simple to control and schedule. The unit can also handle rain, and slopes up to 35%, which is pretty steep for any lawn.

4. Robomow RS630

A leap from the RX20, the Robomow RS630 can handle three-quarters of an acre on a single charge. It’s also able to mow at 20-degree angles. Like its sibling, it has rain detection, and you can use it with Amazon Alexa, not to mention the included app. It costs near $2,000, but more demanding users will appreciate the upgrade.

5. Honda Miimo HRM520

Honda is a well-known car brand, so it might surprise you to know they do robot mowers, too. The Miimo HRM520 can handle up to 2 acres, and slopes up to 25%. A 60-minute charge gets an equal amount of runtime. It’s costly, but definitely one of the best robot lawn mowers around.

6. Husqvarna Automower 435X AWD

The Husqvarna Automower 435X AWD covers 0.9 acres, which is less than some (much) cheaper alternatives, but it makes up for this in other areas. It has all-wheel drive, manages 35-degree slopes, and uses GPS-assisted navigation. Grass height can be set anywhere between 1.2 and 2.8 inches. It also supports both Alexa and Google Assistant.

7. Husqvarna Automower 450X AWD

If the 435X somehow isn’t enough, Husqvarna has another option with even more capabilities. The Automower 450X covers 1.25 acres on a charge, cutting lengths between 0.8 and 2.4 inches, and slopes up to a whopping 45%. Get this: it even has LED headlights!

8. Ambrogio L400i Deluxe

Ambrogio L400i Deluxe - The best robot lawn mowers

If you have vast amounts of grass to cut, it doesn’t get much better than the Ambrogio L400i Deluxe. It resembles a race car, and performs about as amazingly as it looks. It mows up to 5 acres, and runs for 11 hours on a single charge. The unit can also handle 24-degree hills. It’s controlled via Bluetooth or GSM (cellular) with smart assistant support. Expect to pay as much as you would for a new sub-compact car.
