When looking for a robot lawn mower, you must consider several key factors. You have to consider the lawn mower’s total area capacity, battery life, ability to handle slopes, power, smart features, ability to withstand weather conditions, etc. Finally, you have to compare all of these features against your budget to find a lawn mower suitable for your specific needs.Robot lawn mowers are the perfect garden technologies in 2020. Most of us handle household chores like lawn-mowing on our days off work, spending our precious leisurely hours on some more work! But robot lawn mowers can be programmed to automatically mow the lawn before you’re even awake, so you wake up to find a perfectly-trimmed lawn without having to lift a finger.

That’s a lot of work to tackle! But that’s what we’re here for.

At Smart Home News, we’ve handled all the research and comparison work, so you don’t have to. We compile our research and findings to recommend the best robot lawn mowers in five categories — best overall, best value, best budget, best for small lawns (<8,000 sq. ft.), and best for large lawns  (>8,000 sq. ft.).

If you can’t be bothered with the complete article and want a quick recommendation, we suggest checking out Worx WR153 Landroid or Flymo 1200R. The Worx lawn mower is our pick for the best overall robot lawnmower, suitable for medium-sized lawns up to 21,000 sq. ft. The Flymo lawn mower is our budget pick, equipped with basic features and suitable for smaller lawns up to 4,000 sq. ft.

However, we highly recommend going through all the selections in this article carefully. Purchasing a robot lawn mower is a big investment, and you should carefully weigh your options.

Best Overall Robot Lawn Mowers

Worx WR153 Landroid is one of the most advanced Worx robot lawn mowers, capable of cutting up to half-an-acre of lawn with a single charge. It comes with a boundary wire that you can place around your lawn’s periphery and possible obstacles to ensure the lawn mower doesn’t wander off to places it’s not supposed to.

We’re calling it the best overall robot lawn mower because it includes some of the most advanced features, including an impressive cutting height. This lawn mower is suitable for medium-sized to large lawns up to half-an-acre, and it has some pretty amazing terrain mapping skills. It also comes with a Find My Landroid GPS, which is independently priced at $150. If money isn’t much of a factor, this is one of the most impressive and reputable lawn mowers around.

worx best overall robot lawnmower

Specs Overview

  • Battery: 20V
  • Cutting Capacity: up to 1/2 acre (21,780 sq. ft.)
  • Cutting Diameter: 9”
  • Cutting Height: 1.6” to 3.9”
  • Cutting Incline: up to 20°
  • Anti-Collision: ✔
  • Rain Sensor: ✔
  • GPS Tracking: ✔
  • Smartphone Control: ✔
  • Voice Control: x
  • Noise Level: 63 dB

Features

  • Charging: It runs on a 20V battery pack, the same as all other Worx devices. The length of time it works on each charge depends on several factors, including the quality of your terrain. However, the length of time is irrelevant because it automatically goes back to the charging station, recharged within 90 minutes, and then completes the task.
  • Cutting Area: It has a 9” cutting disc that can cut up to half-an-acre of grass (approx. 21,780 sq. ft.). You can easily adjust the robot lawn mower’s cutting height, turning the dial to adjust it between 5 cutting heights, ranging from 1.5” to 4”. You have to simply lay down the boundary wires, select the route through your smartphone app, and let it go!
  • Terrain Mapping: It includes an advanced inertial sensing technology that adjusts its progress according to the terrain. It gets real information on dirt and inclination to adjust the speed and torque accordingly, with the ability to climb slopes up to 20°.
  • Smartphone Control: The smartphone app allows you to monitor the mower’s progress, start and stop it, change its course, and receive updates. You can also create a customized schedule for lawn mowing, either once a day or once a week, according to your preference. The lawnmower can also analyze your lawn and recommend a maintenance cycle.
  • Narrow Paths: It includes a patented AIA technology that allows it to handle narrow spaces that most mowers can’t tackle.
  • Obstacle Avoidance: The Worx WR153 can also sense obstacles that are 5” high and 8” in front of the mower, allowing it to veer away. You can also use the boundary wires to ensure the lawn mower doesn’t bump against smaller obstacles.
  • Rain Sensor: It has a rain-resistant body, but it still avoids the rain because you should ideally cut the grass when it’s dry. When it senses rain, it retreats back to the charging station and waits until the grass is sufficiently dry.
  • Find My Landroid GPS: This robot lawnmower has an inbuilt Find My Landroid GPS cellular module. If your mower is ever stolen or taken off the property, you’ll get notified immediately, and you’ll be able to track it through your phone.

Pros

  • Easily replaceable battery
  • Comes with an inbuilt GPS tracker
  • Has anti-collision sensors
  • The off-limit boundary wires allow you to set a perimeter
  • Works automatically based on personalized or auto-recommended schedules
  • Skilled at terrain mapping
  • Automatically recharges

Cons

  • The cutting height doesn’t go lower than 1.6”
  • Relatively-higher cost because of the included Find My Landroid GPS, which can also be purchased independently at a cheaper rate
  • Lacks voice commands
  • Vague user manual

Ratings

  • SMARTHOME News Rating: 4.5/5
  • Amazon Rating: 3.9/5
  • Worx Rating: 4.1/5

Buy if you…

  • Have a small or medium-sized lawn up to 21,780 sq. ft.
  • Want a single lawnmower that has the most advanced features.
  • Don’t mind paying a little extra for the GPS tracker.

Don’t buy if you…

  • Your lawn is larger than 0.5 acres or 21,780 sq. ft.
  • If you’d rather buy a cheaper lawn mower and get the GPS tracker separately for a lower cost.
  • You like your lawn to be extremely close-cropped.

Runner Up: Robomow RS612

Robomow RS612 is the ideal alternative to the aforementioned Worx mower if you want to trade some of the cutting capacity for smarter features. This robot lawn mower costs about the same as the Worx 153 mower, but it has better features, including Alexa voice integration and rain sensors. You can control this lawn mower using voice commands, without your smartphone. While it’s an advanced voice-activated robot lawn mower, it has a cutting capacity of up to 1/4 acres (10,890 sq. ft.), making it suitable for smaller lawns. So, you have to decide which feature matters more to you — voice activation or greater cutting capacity.

Cost: $1,581.99 on Amazon

Best Value Robot Lawn Mowers

Worx WR150 Landroid provides the best value among robot lawn mowers because it has all the core features as the Worx WR153, but it’s available at a significantly lower price point. This lawnmower also provides great terrain mapping, is suitable for mid-sized or large lawns up to 21,780 sq. ft., and it has advanced obstacle collision and rain sensor features. So, you may wonder how the WR150 is different from the WR153 — why is it cheaper?

Well, Worx WR150 doesn’t come with an inbuilt Find My Landroid GPS, which is used to establish geo-location and warn you when the lawn mower is moved away from the established perimeter. This feature prevents theft and allows you to track the device if someone steals it. However, even though it doesn’t come with an inbuilt GPS tracker, you can purchase and install Find My Landroid GPS separately, which will still be more reasonable than purchasing the WR153.

worx best value robot lawnmower

Specs Overview

  • Battery: 20V
  • Cutting Capacity: up to 1/2 acre (21,780 sq. ft.)
  • Cutting Diameter: 9”
  • Cutting Height: 1.6” to 3.9”
  • Cutting Incline: up to 20°
  • Anti-Collision: ✔
  • Rain Sensor: ✔
  • GPS Tracking: x
  • Smartphone Control: ✔
  • Voice Control: x
  • Noise Level: 63 dB

Features

  • Self-Charging: Worx Landroid is a cordless robot vacuum cleaner that runs on a 20V battery pack. While the amount of time it runs depends on the terrain quality, it automatically retreats to the charging station, when necessary, and resumes cutting once it’s fully charged. It takes 90 minutes to charge completely.
  • Cutting Capacity: The Landroid WR150 has a 9” cutting disc, with which it can be used to mow medium-sized lawns up to 1/2 acre or 21,780 sq. ft. The blade consists of a rotating disc with 3 unique blades, used depending on the terrain quality. It can go up slopes up to 20°.
  • Navigating Narrow Paths: It includes a patented AIA technology used to navigate through narrow passages. It also includes a cut-to-edge feature, allowing it to cut close to the edge of walls, so you don’t have to trim much.
  • Obstacle Navigation: It’s automatically programmed to avoid obstacles that are 5” high or 8” in front of the robot. When it does bump against an obstacle, it automatically moves back and around the object. You can also use the smartphone controls to establish off-limits digital fence that the robot lawn mower avoids. Finally, you can also use boundary wires to establish a perimeter and prevent it from going to forbidden areas.
  • Smartphone Controls: You can access the robot’s cutting routes through the smartphone app, allowing you to detect the cutting path, obstacles, etc. You can also set your own cutting schedules, or ask the robot to analyze the terrain and recommend the ideal cutting schedule for optimal maintenance.
  • Rain Sensors: The Landroid WR150 is rain-resistant, but it still retreats to the charging station when it detects rain. It waits out the rain and only resumes once the lawn is dry.

Pros

  • The battery is easy to replace
  • Automatically charges when the battery is running low
  • Several advanced anti-collision options
  • Off-limit boundary wires to create a safe perimeter
  • Advanced scheduling and smartphone app features
  • Automatically retreats when it’s raining

  • Want a reasonable robot lawn mower with advanced terrain mapping and obstacle avoidance features.
  • Have a small or medium-sized lawn up to 1/2 acre or 21,780 sq. ft.

Cost:

$1,200 on Amazon

Husqvarna Automower 115H is one of the most valuable lawn mowers for people with a small or medium-sized lawn up to 0.4 acres (17,424 sq. ft.). This lawn mower is perfect for people who want something attractive and sleek. While the aforementioned Worx lawn mower looks like a typical garden equipment, this Husqvarna lawn mower looks like a sleek bat-mobile, with an all-black and metallic exterior and large chromatic wheels.

Besides the attractive appearance, Husqvarna Automower can work comfortably while it’s raining, making it suitable for people who live in wet areas with high amounts of rainfall. However, this lawn mower comes second to Worx because it has only the most basic features, such as anti-collision and customizable schedules. It has a lower incline capacity, lower cutting capacity, and it’s not as good at terrain mapping. However, it’s one of the most valuable robot lawn mowers at the $1,200 price point, bringing a good combination of essential features and cutting capacity.

Cost: $1,199.61 on Amazon

Best Budget Robot Lawn Mowers

WINNER: Flymo 1200R

Flymo 1200R is one of the most affordable and bare-bones robot lawn mowers on the market right now, designed for small to medium-sized lawns. It can mow lawns up to 400 sq. meter (4,305 sq. ft.). Besides costing half as much as most other robot lawnmowers, it’s also incredibly easy to install, so you don’t need to spend any additional amount on professional installation. Everything you could possibly need is included in the package — the robot mower, the charging station, a 150-meter boundary wire, and pegs to hold the wires.

However, the low cost means you have to sacrifice several features, including the smartphone controls. Yes, this smart lawnmower doesn’t come with smartphone integration, so you can’t simply turn it on/off or engaging with it remotely. Instead, you have to set the schedules and controls from the LCD screen on the mower’s body. You can set the schedule for the mower, and then forget about it. It has an automatic charging feature, so it automatically retreats to the charging dock when it’s low on battery.

It’s also suitable for slopes, but only with a 14° incline capacity.
  • Automatic Charging: Flymo 1200R mows the lawn independently, without your manual input. When it’s about to discharge, it automatically retreats to the charging station and resumes the task once it’s done.

  • Schedules: You can set the lawn cutting schedules through the LCD screen on the lawnmower’s body.

Runner Up: Worx WR140 Landroid

Worx WR140 Landroid is a smaller and more affordable version of the Worx Landroid series of robot vacuum cleaners, suitable for smaller yard measuring up to 1/4 acres or 1011 sq. ft. This is the runner up in our selection of the best budget robot lawnmower because it’s still steeply-priced, costing nearly $1,000. However, it’s the perfect lawnmower for someone who wants all or almost all the most advanced automation features at the lowest cost possible.

This lawnmower is completely automated, and it includes advanced scheduling features, smartphone integration, rain sensors, and advanced obstacle sensors. The AIA technology allows it to navigate through narrow paths, cut close to the edges, and perform most of the tasks that other advanced robot lawnmowers can do. You can also add a Find My Landroid GPS if you’re concerned that someone may steal it.

Best Robot Lawn Mowers for Small Lawns (<8000 sq. ft.)

WINNER: Robomow RX20

Robomow RX20 is an extremely small and compact robot lawnmower — it measures only 26 x 22 x 12 inches and weighs 27.9 pounds. Since it’s a tiny lawnmower, it’s only suitable for small lawns, measuring up to 1/20 acre (2,180 sq. ft.), and with an incline of maximum 8.5°. It also has a fairly small cutting width of 7”, which means it also takes longer than most lawnmowers.

However, we’re calling this the best robot lawnmower for small yards because it’s also extremely affordable, and it includes all the latest smart features. It’s a compact lawnmower with advanced features available in a relatively-cheap price point. Even though we’ve given it the title of the best robot lawnmower for small laws, it would have been equally deserving of the best value title. It costs less than $1,000 but gives you access to features like Alexa voice commands, rain sensors, and mowing zones.

It has an incredibly low incline capacity of 8.5°, making it suitable for flat terrains only. And the adjustable cutting height of 0.5” to 1.7” ensures you get closely-cropped grass and lawns.
  • Multi-Zone Feature: You can set up different mowing zones with your boundary wires, and it easily travels between up to 5 different zones to complete the mowing action.

  • Bump Sensors: Whenever this robot bumps against obstacles, it moves back, stops cutting, recalculates the path, and swerves around the obstacle.
  • Lift & Tilt Sensors: You can safely lift the robot if you want to clean the blades. The moment this lawnmower leaves the ground, even a little, it automatically turns the blades off.

Runner Up: Lawnmaster L10

Lawnmaster L10 is better than the Robomow RX20 in several key aspects. It is suitable for yards measuring up to 400m2 (4,305 sq. ft.), so it certainly has a greater capacity than the aforementioned Robomow lawnmower. It’s also cheaper than the RX20, costing about half as much. And it charges in 40 to 45 minutes, while the RX20 takes 16+ hours. That may beg the question — why is it a runner up instead of the winner?

Well, we’ve chosen Lawnmaster L10 as the runner up because it lacks advanced smart features. It’s great at cutting your lawn, it comes with an auto-charging feature, and you may also argue that its better at the core lawn mowing features. However, it doesn’t come with smartphone controls, voice controls, or advanced terrain mapping and obstacle avoidance features. So, the choice between whether you should get the L10 or RX20 depends on your priorities — how important are smart features to you?

Best Robot Lawn Mowers for Large Lawns (>8000 sq. ft.)

WINNER: Robomow RS630

Robomow RS630 is our pick for the best robot lawn mower for large lawns because it can effectively mow yards measuring up to 3/4 acre (32,760 sq. ft.). It has one of the largest cutting blades amongst robot lawnmowers and incredible terrain mapping skills that allow it to cover vast swathes of land with uneven surfaces.

This lawnmower isn’t merely great at cutting large lawns. It’s also one of the most feature-rich lawnmowers, complete with rain sensors, Alexa voice capabilities, anti-theft features, and different mowing zones. Sure, it’s also one of the more premium-priced lawnmowers, but it’s well worth it considering the wide range of advanced smart features, speed, battery power, and cutting capacity.

The cutting height can be adjusted between 1.3” to 3.5”, making it suitable for most lawns, but it doesn’t provide a close-cropped look that some prefer.
  • Multiple Zones: You can create up to four autonomous mowing zones. The lawnmower will automatically move from one zone to the next, stopping the blades when crossing the region between the mowing zones. Once it’s done, it will automatically return to the charging station.

However, you can also engage the rain sensor to make the mower retreat to the charging station, and resume mowing once the lawn has dried.
  • Anti-Theft Alarm: It comes with an inbuilt alarm that gets triggered whenever the mower is manually removed from its designated spot. When that happens, you have to stop the alarm by entering a PIN code. This ensures no one can steal your lawnmower.

Husqvarna Automower 450X is currently one of the most advanced robot lawnmowers, suitable for vast estates and commercial properties. It exceeds the aforementioned Robomow lawnmower both in terms of cutting capacity and cutting height. It has a cutting capacity of 1.25 acres (54,450 sq. ft.), and a cutting height ranging from 0.8” to 2.4”. Besides an extremely powerful cutting blade that ensures you maintain closely-trimmed lawns in large estates, it also has advanced smart features.

The Automower 450X includes a GPS system, remote object detection, Alexa voice controls, lift & tilt sensors, advanced scheduling, and advanced anti-theft features. To top it off, it’s also incredibly sleek and attractive. The only reason we’ve placed this in a runner up position is that it’s incredibly expensive, costing over twice as much as the RS630, which is already a premium-priced product in its own right. You should only consider purchasing this robot lawnmower if money and budget aren’t an issue at all.

Conclusion

We’ve recommended a bunch of lawnmowers in this article, divided across various categories and utilities. However, you should consider our picks as guidelines rather than hard-and-fast selections.

For example, we’ve chosen Robomow RX20 as the best lawnmower for small lawns because it’s affordable and has awesome features, but you may prefer Lawnmaster L10, which is cheaper and better at mowing but lacks smart features.

Selecting the best and runner-up mower for the various categories is ultimately fairly arbitrary. It’s all a matter of trade-offs. Do you want to pay more for smart features? Do you prefer a mower that’s better at its core functions, or one that has more features but weaker core functions?

Based on how you answer these questions, your personal idea of what’s the best mower may be completely different from ours. So, consider all your options carefully, and make an informed purchase decision.
