1. Worx WR150 Landroid

The best robot lawn mower overall

WORX WR150 Landroid L 20V Power Share Robotic Lawn Mower

Brand: Worx / Cutting Height: 1.6”-3.9” / Cutting Width: 9” / Max Cutting Surface: 0.5 Acres / Max Incline or Decline: 20° / Installation Kit Included: Yes / Price: 💰💰💰

Up first, we have Worx WR150 Landroid Robotic Lawn Mower. Out of all the models we looked at, this was the best-rated robot lawn mower. It’s equipped with what they refer to as AIA (Artificial Intelligence Algorithm) that allows it to successfully learn even the most intricate yards and navigate through them while steadily improving.

The max incline/decline of the Landroid is only 20-degrees, which may influence your decision if your yard contains more dramatic increases in slope. It includes rain sensors that will send the robotic lawn mower back to its charging base during rainfall. It also returns when the battery is low, so you won’t have to go out and drag it back to the charging station.

  • It learns your yard quickly
  • Customizable schedules
  • Great customer service from Worx

  • Gets stuck in tricky spots in the yard
  • Can’t navigate around short items

2. Worx WR143 Landroid

The best robot lawn mower runner-up

Worx WR143 Landroid M 20V Power Share Robotic Lawn Mower with GPS Module Included

Brand: Worx / Cutting Height: 2”-3.5” / Cutting Width: 7” / Max Cutting Surface: 0.25 Acres / Max Incline or Decline: 20° / Installation Kit Included: Yes / Price: 💰💰

Our runner-up is another fantastic, environmentally friendly robot lawn mower from Worx. We highlight this as one of Worx’s best electric robot lawn mowers.

This model is very similar to the other Worx model on our list and comes with most of the same features. If you’re struggling to choose between the two, rest assured that you’re not alone. We had a hard time deciding between the two models as well.

The most significant difference between the two Worx mowers on our list is that this one comes with GPS and the other model covers more ground. We suggest letting the size of your lawn decide for you.

  • GPS included
  • Works well on small slopes
  • Worx customer service unparalled

  • Initial setup was difficult
  • It might take a while to get it to navigate around problem areas

3. Gardena R80Li

The best green pick for robot lawn mowers

Gardena 4069 R80Li Robotic Lawnmower

Brand: Gardena / Cutting Height: 0.7”-2” / Cutting Width: 6.7” / Max Cutting Surface: 0.2 Acres / Max Incline or Decline: 25° / Installation Kit Included: Yes / Price: 💰💰💰💰

Besides being our green pick because of its low energy consumption, we also think the Gardena R80Li is the best lawn mower robot for a small garden. Its size allows it to navigate through small spaces and work around complex structures easily.

One of the things we love about Gardena’s robotic mower goes beyond just the product itself. No matter which model you get from them, their website is chock full of instructional videos and customer support, which might put some first-time buyers at ease about using this new machine. The quality of Gardena’s R80Li is not to be rivaled. It’s considered a midline mower in their books, but for the money, it’s easily among the best.

  • Easy to program
  • Good at navigating small spaces
  • Works well in rainy climates

  • No smartphone app
  • It can’t be programmed remotely

4. MowRo RM24

The best budget robot lawn mower

Mowro 4.0 Ah Lithium-Ion Easy, Safe, Fully Autonomous Robotic Lawn Mower with Install Kit

Brand: MowRo / Cutting Height: 1”-2.5” / Cutting Width: 9.5” / Max Cutting Surface: 0.25 Acres / Max Incline or Decline: 30° / Installation Kit Included: Yes / Price: 💰💰

For a budget choice, the MowRo RM24 has a lot to offer. It’s better at dealing with slopes than most of the other models we came across. It also seems to do fairly well even when the ground is a bit uneven.

This is an excellent option for someone who wants a fully autonomous mower and doesn’t want to bother with using an app. Once you tell the mower the size of your yard and the time of day you want the cycle to start, its algorithm takes over and sets up the rest of the scheduling details for you. It will take one full pass at your lawn every 48 hours to keep it looking fit and trim.

Even though it’s not waterproof, this mower does have a rain sensor that will send it back to its charger to wait out the storm.

  • Can handle 30-degree slopes
  • Navigates uneven ground without a problem
  • You can set it and forget it because it’s fully autonomous

  • No app
  • No ability to create or tweak your own mowing schedule

5. Husqvarna Automower 315

The best robot lawn mower for small lawns

Husqvarna Automower 315 Automatic Robotic Lawn Mower w:Free Small Install Kit

Brand: Husqvarna / Cutting Height: 0.8”-2.4” / Cutting Width: 8.7” / Max Cutting Surface: 0.4 Acres / Max Incline or Decline: 22° / Installation Kit Included: Yes / Price: 💰💰💰

If you’re looking for a Husqvarna robotic lawn mower for a smaller lawn area, the Automower 315 is the option for you. It can handle more than a quarter acre with a tri-blade system that will cut your grass evenly on surfaces up to 22° in slope.

It’s quiet enough to work at any time of day and won’t need to be monitored. It can also handle different weather patterns and adjusts its cutting schedule based on how quickly your grass is growing to avoid over-trimming.

Also, unlike most other Husqvarna models, this one comes with an installation kit.

  • Works well on slopes
  • Navigates complex yards
  • Very quiet

  • Less than desirable customer service from Husqvarna
  • GPS not included

6. Robomow RS630

The best robot lawn mower for large lawns

Robomow RS630 Battery Powered Robotic Lawn Mower

Brand: Robomow / Cutting Height: 0.8”-3.5” / Cutting Width: 22” / Max Cutting Surface: 0.75-1.24 Acres / Max Incline or Decline: 20° / Installation Kit Included: Yes / Price: 💰💰💰💰

Robomow is another brand with multiple models on the market, but we have chosen to feature one of their more heavy-duty releases in our robotic mower reviews. With an installation kit included, the RS630 rivals similar models in both price and durability. Also, it’s great at handling slopes and wet grass.

Depending on how you’d like to monitor your robot mower, you can also have it set to quit operating during heavy rain and even humidity. For places that have higher humidity levels, even without rain, this is a crucial feature. The mowing width is almost two feet meaning it can cover more yard in less time.

  • Does a good job of mulching
  • Lots of customizable features
  • Helpful tech support

  • Expensive replacement parts
  • Some issues with getting stuck

7. Husqvarna Automower 430XH

The best premium pick for robot lawn mowers

Husqvarna Automower 430XH Robotic Lawn Mower

Brand: Husqvarna / Cutting Height: 2”-3.6” / Cutting Width: 9.45” / Max Cutting Surface: 0.8 Acres / Max Incline or Decline: 24° / Installation Kit Included: No / Price: 💰💰💰💰💰

The Husqvarna Automower 430XH Robotic Lawn Mower has one of the broadest acre coverage we’ve seen. The strong battery takes less than an hour to recharge when it’s completely drained.

We do have to note that most Husqvarna robotic mowers do not readily come with an installation kit; this one is the same way. This can actually be beneficial to you because Husqvarna has many different sizes of installation kits available, so you can choose the one that best fits your needs.

One of the neatest features about this robot is its ability to find its way home to you – so to speak. Essentially, it has a GPS feature that enables you to track it from your smartphone in case anyone attempts to steal it. Pretty spiffy.

Plus, if we’re honest, it looks like the robot lawn mower that Batman would use – which is sort of an added bonus.

  • Lots of customizable features
  • Works with a smartphone, Alexa, and Google Home
  • Quiet and safe

  • Doesn’t come with an installation kit
  • Can get stuck in uneven yards

8. Husqvarna Automower 450X

The best robot lawn mower for commercial use

Husqvarna Automower 450X Robotic Lawn Mower

Brand: Husqvarna / Cutting Height: 0.8”-2.4” / Cutting Width: 9.45” / Max Cutting Surface: 1.25 Acres / Max Incline or Decline: 24° / Installation Kit Included: No / Price: 💰💰💰💰💰

If you’re looking for the best, biggest robot lawn mower, the Husqvarna 450X is what you want. With a cutting capacity of 1.25 acres and the ability to run for 270 minutes on a single charge, this model is far ahead of the rest. Also, the typical charging time is only one hour. It’s the best commercial robot lawn mower that goes the distance without raising the price tag too much.

As far as features go, this Husqvarna is almost identical in every way to the other 430XH robotic lawn mower we have featured in our review section. The biggest difference? Size capacity. The battery in this model is just slightly stronger so that it can handle over one acre of mowing area.

If you are okay with it running multiple times in a day, you can likely push the acreage up to 1.5.

  • Works with a smartphone, Alexa, and Google Home
  • Lots of customizable options and features
  • Can handle large lawns and is quiet

  • Less than desirable customer service
  • You’ll still need to clean up larger yard debris for this to work properly

9. Robomow RS612

The best versatile robot lawn mower

Robomow RS612 Battery Powered Robotic Lawn Mower Small Yard

Brand: Robomow / Cutting Height: 0.8”-3.5” / Cutting Width: 22” / Max Cutting Surface: 0.25-.75 Acres / Max Incline or Decline: 20° / Installation Kit Included: Yes / Price: 💰💰💰

This mower offers almost all of the same features as the other Robomow model on our list. This is another situation where deciding between the two models is all about the size of your yard.

If you have a smaller yard, this might be the better choice of the two Robomow options on our list. However, something to keep in mind is that even though this model can handle .75 acres, .25 is what’s recommended. If your yard is closer to the larger end of the allowance, you might want to opt for the other model.

  • Good at cutting thick grass
  • Works with smartphone and Alexa
  • Lean green grass chopping machine

  • Not the best customer support
  • Some had issues with parts needing to be replaced

10. Husqvarna Automower 310

The best value robot lawn mower

Husqvarna AUTOMOWER 310

Brand: Husqvarna / Cutting Height: 0.8”-2.4” / Cutting Width: 8.66” / Max Cutting Surface: 0.25 Acres / Max Incline or Decline: 22° / Installation Kit Included: No / Price: 💰💰

If you’re looking for the best robot lawn mower under 1000 dollars, we think the Husqvarna Automower 310 is your best option. It’s a great mower from a brand with a good reputation for their machines.

Although this model doesn’t come with all the features that some of the higher-end Husqvarna models offer, it still offers a lot. Like the other Husqvarna models on our list, this mower is weatherproof, is low on energy consumption, and has no emissions.

This model doesn’t have the GPS-assisted-navigation, the weather timer, or the larger display that some other models have. However, the smaller price tag makes this model a great value.

  • The smartphone app works well
  • Easier to set up than some other models
  • Lawn is thicker and greener after regular use

  • Doesn’t come with GPS, but it can be installed
  • Short battery life between charges

What to Look for in a Robot Lawn Mower

We try our best to cover the most essential features in our robotic lawn mower reviews and what you might need to consider before buying. We want to help you pick the best home robot lawn mower for your needs. We encourage you to read through the details of the important features below before investing in a mower. Some of them are so crucial that if you neglect to consider them, you won’t be able to properly use your new robotic lawn mower.

Robot Lawn Mowers - What to Look for

1. Cutting Capacity

The size of your yard might be the first thing you’ll want to consider when it comes to deciding on the best robot lawn mower for your lawn. It’s also a great way to start narrowing down your options. Unlike some of the optional features, the cutting capacity of the mower is critical. Going with a model that can handle a larger yard is fine, but don’t opt for a mower that can only handle something smaller.

2. Cutting Height

Cutting height is something important to consider before buying a robotic lawn mower. Know what you want as an end result before you purchase. Likewise, cutting height positions available might also impact your choice. Even if a mower has a wide range of heights, it doesn’t mean that there are enough settings to choose from within that range.

3. Cutting Width

Depending on your lawn’s size and shape, you might require a narrower or wider cutting width on your mower. Wider can mean less time in a traditionally shaped lawn, but narrow robot lawn mowers can fit more easily in tight spaces and cut more intricate lawns.

4. Slope

Some robotic lawn mowers can handle more dramatic slope increases and decreases than others. Measure the inclines of your lawn before buying one if you’re concerned. For robot mowers, the slope is usually expressed as either a degree or a percentage. It’s important to note that these are not the same. For instance, a mower that offers a slope capability of 20° is equivalent to a mower offering a slope capability of 36.4%.

5. Installation Kit

Some of the robot lawn mowers on our list come with their own installation kit so that you can get started hassle-free. However, not all installation kits are made the same. If you need a larger kit, it might be better to have the option to buy the kit separately. This can also help you save money if you already have an installation kit set up and just need to buy a new or additional unit for your lawn mowing needs.

The most frequent complaints we saw from reviewers had to do with the difficulty of the initial installation and boundary wire issues. We wish we could recommend the best robot lawn mower without a wire boundary, but it just doesn’t seem like there are any good options out there yet. Keep checking back with us, though. If any good options become available, you can be sure we’ll add them to our list. In the meantime, for the best results and less time spent through trial and error, we recommend prepping your yard ahead of time and following the installation directions carefully. Maybe even watch a couple of how-to videos.

6. Cost

A big hold up for some people wanting to purchase an automatic lawn mower can be the initial cost. However, even a small yard can cost the average family over $1000 a year if you’re paying for regular mowing services. For some robot mower models, you’ll save more in just one year of using it (including electric charging costs). The key to a healthy lawn is more regular trimmings at a lower setting.

Even if you aren’t outsourcing this task, it might still be eating up too much of your time — especially for those weekend warriors out there. Investing in a robot lawn mower can help keep your lawn healthy, ensuring fewer renovation costs down the road, and it will save you either time, money, or both.

Top Robot Mower Brands

When you start looking for quality robot lawn mowers, there are a few of the best robot lawn mower brands you are likely to come across.

Husqvarna Robotic Mower

A commonly trusted brand name in landscape maintenance is Husqvarna. They have over 3 centuries of power equipment manufacturing under their belts. You didn’t read that wrong. Over 300 Years. And, they haven’t lost their touch. There are plenty of Husqvarna Robotic Mowers available to consumers at reasonable prices.
Even for the pricier models, you are likely going to save more money after just one year of using a Husqvarna robotic mower than you would save paying someone to mow your lawn a couple of times a month. Husqvarna also has the most models currently available on the market.

Worx Robot Mowers

Perhaps a less well-known brand in the average household is Worx, but they’ve already made quite a reputation for themselves in the robot mower game. Their modern looking machines are user friendly and extremely advanced. Aside from just using sensors, units such as their Landroid Robotic Lawn Mower are equipped with AI Algorithms to help it navigate more intricate lawns and cuts. They are much more than good-looking robots, but that’s a bonus as well.

Robomow

Robomow has been working on robotic mowers since 1995. Although they’re known by their brand name, Robomow, the company’s name is actually Friendly Robotics. They make durable machines, with lots of useful features, at a reasonable price. And, with a name like Friendly Robotics, it’s no surprise that these machines are equipped with safety features to keep the whole family safe.

Do Robotic Lawn Mowers Even Work?

Best Robot Lawn Mowers Featured

We have answers for the skeptics out there wondering, “Do robotic lawn mowers work?” Like all tools and robotic machines, robot lawn mowers are not without their faults. But more importantly, they will only work if used correctly. Much like a smaller automatic vacuum cleaner such as the Roomba, these machines work better if used multiple times a week.

The goal of an automatic lawn mower is to maintain, not to do drastic makeovers.

Using a robot mower regularly to cut short lengths will prevent the machine from clogging up. Much like a vacuum, if you only are using it once a week or every other week, then it takes longer to complete and often needs cleaning due to clogging up.

Likely, if you’re interested in investing in a robot lawn mower, you are already in the maintenance game and would like to spend that extra hour or two a week on something more worth your time. After all, lawns are considered a luxury, and we believe they should be treated as one.

Advancements in Robot Lawn Mower Technology

We all probably knew the robot lawn mower wasn’t too far away when we saw the rise of the automatic vacuum cleaners such as the Roomba. With recent technological advancements, automatic lawn mowers, or robotic lawn mowers, have started to make a name for themselves as a regular suburban power tool. However, a mower, as compared to a vacuum requires a lot more power and better visual tech. Manufacturers knew they were playing with fire. They certainly didn’t want to unleash a rogue machine with the ability to chop up anything that crossed its path. Nevertheless, progress has prevailed.

Advancements in Robot Lawn Mower Technology

Here are some of the areas where robot mowers have seen steady improvement:

Mapping. One major difference between a robot vacuum cleaner and a robot lawn mower is how the machine will map out — or “learn” — your yard. Most Robot lawn mowers come with a low voltage wire that you essentially place around the area of your lawn. The mower will not go past this perimeter as long as it is properly installed. Avoiding a runaway lawn mower is obviously crucial, and it seems like the premise of a bad horror movie.

Sensors. Robot mowers also have bumping sensors, and they are much more accurate than they used to be. Even something like a garden hose or lawn ornament, that could quickly be taken out by push or riding lawn mowers, will be enough to stop an automatic lawn mower and send it cutting the other way.

Safety. As previously implied, some of you might be feeling uneasy about the safety of automatic mowers, particularly if you have children or pets. The improvements made to the lawn mowers sensitivity is a step in the right direction. It should also be noted that robotic lawn mowers essentially have a kill switch on the blades that is activated if the machine is lifted or off-kilter. Overall, as long as you spend time properly installing the low-voltage wire perimeter, read all instructions, and spend some time observing your machine during its first few uses, we feel confident that it will be safe for you and your family.

Environment. One of the great things about robotic motors is that they are electrically powered, rather than gas-powered, and their wireless operation makes them even less of a hassle. So, if you’re looking for the best gas robot lawn mower, you won’t find it on our list. If you want to go an extra step in making your robot even more environmentally friendly, it’s possible to set it up to get its charge from a renewable source such as a solar panel charging system. Check the voltage, but there are plenty of compatible panel systems out there that are incredibly affordable.
