Best Robot Lawn Mower Reviews – Top 6 Picks

1. Flymo 1200R Lithium-Ion (Editor’s Choice)

Flymo 1200 ROut of all of our robot lawn mower reviews, our favourite choice is the Flymo 1200R. For trimming lawns up to 400 sq m, this sturdy mower is perfect for the job, making it ideal for homes with average-sized, small to medium gardens.

Features

The Flymo 1200R robotic lawn mower has an automatic self-charging system. It’s ideal if you are looking for a model that you can install and leave to get on with keeping your garden in shape. You can also adjust the cutting height to a length that best suits your lawns via the handy dial. Length range is between 20 to 50mm with a 17cm cutting width, which is plenty of range for standard lawns.

This model uses a random grass mowing pattern to ensure that all areas of your garden are covered. Suitable for lawns with inclines up to 25%, it also reverses then changes direction if it comes into contact with any objects. These features make this robot lawn mower more efficient, as it spends less time out of action waiting for you to intervene.

Complete with a PIN code and a lift sensor for security, the Flymo 1200R is also extremely discreet with a low 59dB sound volume. Perfect if you live in a built-up area, as your neighbours won’t notice if you schedule it to come on overnight when your garden won’t be in use.

However, according to some reviews, this is not the best robot lawn device for detailed mowing as this couldn’t cut the sides. Thus, you’ll still have to do it manually from time to time. Also, the installation can drag on a bit and you’ll have to very carefully position its docking station. Overall, the Flymo 1200R is one of the easiest to use and gets the job done more efficiently than other robotic lawn mower options.

Pros:
  • Suitable for larger lawns up to 400 m2
  • Powered by lithium-ion battery
  • With docking station for automatic self-charging
  • Variable cutting heights
  • For gardens with inclines up to 25%
  • Works discreetly at 59dB
Cons:
  • Not the best robot lawn machine for cutting edges
  • Lengthy installation process
  • Strict dock location positioning

2. McCulloch ROB 1000 (Luxury Choice)

Mcculloch ROB 1000If you want to really treat yourself, take a look at our luxury choice – the McCulloch Rob R1000. This model makes a great pick for larger gardens, being suitable for lawns up to an impressive 1,000m2 range.

Features

Fully programmable, simply schedule this robot lawn mower to work whenever is convenient for your household. You can also adjust the cutting height to be sure that your garden is always kept to your desired length. It can be adjusted anywhere between a minimum of 20mm and a maximum of 50mm.

This lawn robot mows in almost all weather conditions. It will continue to cut the grass through the rain, unlike other robot mowers which return to base once raindrops appear. The ROB R1000 can tackle slopes of up to 25% and will only pair with its own individual base – an extra security measure aside from the usual PIN and alarm function. There is also a one-year warranty included for your peace of mind.

Even though this robot lawnmower is easy to program and features obstacle avoidance, some reviews found this function to be unreliable. Therefore, if you have kids or pets in the garden, it would be advisable to use it only under supervision or overnight. For this reason, unless you have an extra-large garden that other robotic lawnmowers would struggle with, we can’t justify the extra cost of this particular model for small gardens. Also, like most robot lawnmowers, finding a suitable home base location can be a little tricky.

However, on the whole, this is an excellent quality robotic lawn device. For those who need an easier solution to keep their large lawns looking immaculate, the ROB 1000 is the answer.

Pros:
  • Up to 1,000 square metres lawn area
  • Fully programmable with alarm function
  • Works in any weather conditions, rain or shine
  • Adjustable cutting height with 17cm cutting width
  • With free cutting blades
  • One-year warranty
Cons:
  • Obstacle avoidance can be unreliable
  • Restrictive base station position
  • Expensive

3. LawnMaster L10 (Budget Choice)

LawnMaster L10Easy to use and reliable, the LawnMaster L10 is a fantastic choice for anyone who wants to spend less time on their lawn, and more time enjoying their garden.  With a one-time set up of the boundary wire, you can leave this device to mow the lawn and even expect it to charge itself at timely intervals.

Features

What’s really great about this model by LawnMaster is that once you’ve set your system up, it will automatically operate every day with no need for an external app. The device charges itself, and it’s quiet enough that you’ll barely notice it’s there.

In addition, because the LawnMaster brand only uses the best materials, you also get a tough and durable device that’s rated IPX5 for waterproof performance. There’s even a 2-year warranty.

The L10 comes with mulching action built-in, to return your cut grass back to the lawn to help with growth. For extra security and safety, there are also lift, tilt, and bump sensors included to stop the blades if the mower is picked up. As an extra safety feature, it comes with a PIN code to help protect from unauthorized use.

One downside is that this mower doesn’t collect the grass, which may be an issue for some homeowners. Additionally, the wheels can sometimes get clogged.

Pros:
  • Easy to use and set-up
  • Low maintenance
  • IPX5 rating
  • Durable design
  • With built-in safety and security features
Cons:
  • May not be for those who prefer mowers that collect grass
  • Wheels can become clogged

4. WORX WR142E M700 Landroid (Best Value)

WORX WR142E M700 LandroidThe Landroid M700 by Worx is a popular lawn mower that makes cutting grass a breeze for lawns measuring 700 square metres.

Features

One notable feature of this smart robot lawn mower is that it’s self-programming. Unlike other products that need to be programmed and set up, the Landroid uses Smart Auto Scheduling to cut your lawn more efficiently. It has the ability to learn about your garden over time and create its own specially adapted mowing schedule. Not only does this make for a better lawn as it adapts its mowing to the current grass growth rate, but it also takes the hassle and guesswork out of setting it up.

Another great advantage of this particular robot mower is that it is customisable. It offers an option to add on extras at a later date if required. This keeps the price low while giving you the choice of upgrading – if and when you wish to do so. Additional optional extras include voice control, radio link, off-limits, collision sensors, and a GPS tracker. Also, it is Worx battery PowerShare compatible, meaning you can use it with other Worx power tool batteries. For long-lasting performance, it automatically returns to the charging station to recharge.

Efficient AIA (artificial intelligence) technology allows this lawn robot to efficiently mow your lawns without needlessly going backwards and forwards over the same area multiple times. However, it does not cut to the edge, so you’ll still need to do some trimming yourself once in a while.

Also, note that this robotic lawnmower is not suitable for use with two disconnected lawns. That is if there’s a pathway dividing them. Furthermore, while there is a user manual online, there isn’t a paper copy provided in the box. Nonetheless, minor niggles aside, this lithium-ion battery-powered Landroid makes an excellent choice if you have a continuous lawn.

Pros:
  • For lawn area up to 700m2
  • Battery Worx PowerShare compatible
  • Variable height options with 18cm cutting width
  • Uses a programming assistant – Smart Auto Scheduling
  • Features efficient AIA technology
Cons:
  • Doesn’t cut the edges
  • No paper manual provided
  • Not suitable for two disconnected lawns

5. Yard Force Amiro 400i with Ultrasonic Sensor (Best App-Controlled)

Yard Force AMIRO400iThe Amiro 400i certainly isn’t lacking in technology or performance. It effortlessly tackles sloping gardens, capable of taking on inclines of up to 30%. So, if you have a small to medium lawn area of 400 square metres or less with some steep sloping areas, the Amiro could be the best robotic lawn mower for your garden.

Features

It also presents three different cutting heights to ensure that it leaves your lawn mowed exactly to your preference.

In spite of its modest price, this robot lawn mower can be controlled remotely via its app. A function which some expensive models fail to offer. It also features ultrasonic sensor technology for safer, more effective mowing and better obstacle avoidance.

While these are fantastic advantages to this machine, bear in mind that it does not mow under the rain. Therefore, if your area typically experiences frequent rain showers, you may need to consider a different model that will continue to mow in the wet. Even though it breezes through slopes within the perimeter lines, it can struggle somewhat with uneven lawns. So, you may want to level yours out slightly before using. However, this is pretty much standard advice for all robot mowers.

The main drawback to this smart lawn robot is its poorly translated instructions which lack clarity and depth. However, as this is a seriously good machine that represents excellent value for money, we think it’s well worth spending a little extra time finding out exactly how to use it.

Pros:
  • For lawn sizes up to 400m2
  • Remote control via app
  • Ultrasonic sensor technology
  • Tackles slopes up to 30%
  • Features three cutting heights
Cons:
  • Not the ideal machine for rain or shine mowing
  • Poorly translated guide
  • Can struggle with uneven lawns

6. Bosch Indego S+ 350 with App Function

Bosch Indego S+ 350If your lawn is within 350-square metre range and you are looking for an intelligent lawn robot, check out the Bosch Indego S+ 350.

Features

This robotic lawnmower can be controlled remotely via its app or voice control with an Alexa device for ease of use. With its fast 45-minute charge time, additional coloured covers, and a security PIN code, plus in-app tracking – the Bosch Indego auto lawn mower is one tough contender.

Performance-wise, the Indego 350 uses LogiCut navigation system to calculate the most efficient route around your garden. It then mows methodically, making it not only faster than random navigation models but also more effective. Thanks to its SpotMow and MutiArea features, you can use this smart lawn robot in non-continuous lawns, as well as mow isolated overgrown areas. With automatic docking and charging, the Indego can be left to get on with what it does best – keeping your lawn looking great.

Unfortunately, the docking station’s power socket is not waterproof, meaning you’ll have to be careful where you place it. Also, the power cable is very short at only around three metres long. In terms of the mower itself, we think the drive wheels could benefit from a deeper wheel tread to resist sideways movement.

However, for a highly efficient and intelligent auto lawn mower, the Indego S+ is one of the best robot models that will make light work of your overgrown garden.

Pros:
  • Suitable for lawn areas up to 350 sq m
  • Control remotely via app or Alexa
  • Efficient LogiCut navigation
  • Automatically returns to docking station to recharge
  • SpotMow and MultiArea features
  • With a lithium-ion battery and perimeter lines included
Cons:
  • Power socket not waterproof
  • Wheel tread could be deeper
  • Short power cable

Robotic Lawnmower Buying Guide

With a lot of robot lawnmowers on the market today, it’s indeed a daunting task to go over every option. To make it easier for you to hit a buy button, we have listed certain significant factors and features that you’ll need to consider to reach a more informed decision.

Are Robot Lawn Mowers Any Good?

While the idea behind robotic lawn mowers is appealing, people often wonder do robot mowers work? Are they any good? To get to grips with this question, let’s take a look at some of the benefits of robot mowers – to help you decide whether to buy one for your garden.

a. Saves Time

auto lawn mower at workEven a small garden can take a huge chunk of your leisure time away when it comes down to trimming your lawn with a traditional mower. Not only do you have to get the mower out, but you also have to push and regulate it. Then you have to empty the mower out afterwards, finding somewhere suitable to get rid of all of your cuttings.

If you have a large lawn that you feed regularly, not only will the actual mowing take a long time, you’ll also have to stop several times to empty your mower. However, with a robotic lawnmower, you can simply leave it to get on with keeping your lawn nice and trim. The best robot mower will make sure you reclaim your fabulous weekends without neglecting your garden.

b. Programming Options

Robot mowers are highly convenient. Set yours to mow at night, early in the morning or when you’re out at work – it’ll get the job done, rain or shine. That way, your lawn will always be looking its best when you want to enjoy it.

c. No Grass Cuttings

As a robot lawn mower cuts the grass at minimal amounts, you don’t have any grass cuttings to dispose of, unlike with regular lawn mowers or other garden tools. Once your lawn is cut down to size, your robotic mower will trim only 1-3mm of grass each time. These small clippings will naturally disperse over your lawn where they will disappear in no time.

d. Healthier Lawn

Not only will your garden have that “freshly mowed” look permanently, but the small regular grass clippings will enrich the soil naturally. Hence, it’ll enhance your grass quality and your lawn’s overall appearance.

e. Quiet

robot mower working at nightIf you’ve got neighbours nearby, you’ll likely know just how annoying it is when you’re trying to lie in or enjoy outdoor entertaining, when someone starts up their traditional lawn mower. However, as the best robot lawn mowers are really quiet, you won’t disturb your neighbours or your household – even if you set it to mow overnight.

f. Safe

Traditional lawn mowers can be tricky to use and, if they are corded, you have to be extra careful not to mow over the cable. Robot lawn mowers are much safer, as they are low to the ground. This means they will not mount any obstacles – as you may inadvertently force your traditional mower to do.

Your machine will take care of your lawn without needing to push it around. Thus, it eliminates any risk of accidentally electrocuting or cutting yourself while trimming your lawn.

How to Choose the Best Robotic Lawnmower

When you are choosing the best robot lawn mower, it can be helpful to keep an eye out for certain features. Here are some of the main ones to consider:

a. Lawn Area

You’ll need to first work out the size of your lawn in metres squared. This will enable you to match your lawn size to an appropriately equipped robot lawnmower.

As lawn robots frequently cut very small amounts of grass, you must pick a machine that is suitable for your garden size. If you pick one with a lower capacity then you’ll risk ending up with an overgrown lawn.

On the other hand, if you pick a model with a much greater capacity, then you’ll end up spending a lot more than necessary.

b. Programmable

Chances are you’ll want to have the option to program your lawnmower to cut the grass at a time that’s convenient for you, preferably when your garden is not in use.

Before purchasing your robotic lawn mower, check what scheduling alternatives are available and how easy it is to set up. Most manufacturers provide user manuals on their websites. It can be useful to check out the manual of your preferred models to see exactly what set up entails.

c. Perimeter Wire

setting boundary wiresAlways double-check exactly what is included with your lawn robot. This is especially important if you have a large or awkwardly shaped lawn with plenty of areas that will need to be avoided.

Be sure to pay attention to the amount of perimeter wire or boundary wire and the number of pegs and connectors that are included. A quick measure of your lawn boundaries will give you a good idea of whether or not you will need to order extra supplies.

The length of perimeter wires included can vary between products. Some have a 100-metre boundary wire included, so it’s definitely worth checking out first.

d. Navigation Model

Smart robot mowers use navigation technology in cutting the grass effectively and efficiently. Mowing your lawn using systematic navigation is faster. Moreover, it stops certain areas from becoming muddied from the unnecessary passage of your mower during wetter times of the year.

However, random navigation models are generally cheaper in price and have the ability to manage awkwardly shaped lawns with a lot of obstructions.

e. Cutting Length

Most robotic mowers have adjustable cutting lengths. Selecting a height that looks good for your lawn and its regrowth rate will help you to make sure that your garden looks in prime condition.

It is recommended that you mow your lawn slightly longer at the beginning of spring, then slightly shorter once your grass is growing lush and green. If summer is very dry, it’s better to allow gardens to grow a little longer by raising the cutting height. This will help your grass to recover better from the dry spell.

Having the option to adapt your cutting height to the seasons will ensure your lawn thrives and looks great all year round.

f. Power Cord

You’ll need to carefully consider where to locate your charging station so that it’s near to an electrical socket while remaining in accordance with the manufacturer’s dock location guide.

In some cases, you may need to install an outdoor socket or provide extensions to achieve this. The former is often preferable and you should always ensure that any outdoor electrical installation is fully waterproof.

g. Battery Runtime and Recharging Period

a robot mower's charging stationYou should check how long your battery will last before it returns to its charging station and how long the recharging takes. This is especially important if your lawn is near to the mower’s upper lawn size recommendation. It’ll need to run back to its station to recharge more often to keep large lawns neat and tidy.

Typically, most lawn mowers will have a maximum battery runtime of between 45-60 minutes. Check the manufacturer’s information to learn about your robot lawnmower’s battery life.

While an extra 15 minutes may not sound that much, it can soon add up when a mower spends several hours cutting the grass for large gardens.

h. Incline Capacity

If your lawn slopes, be sure to look out for a lawn robot that features a good slope capacity. Many robot mowers function best on level lawns. However, some of the best robot lawn mowers have been optimised to tackle inclines of up to 30%.

i. Wheels

Wheels are often overlooked when making a model selection. However, they are extremely important for your mower’s stability and manoeuvrability. A set of wheels with a greater surface area and a deep tread invariably mean better performance when turning or avoiding obstacles, and will give better all-round functionality cutting the grass even if it’s wet.

j. Sensors

Sensors help your mower to avoid obstacles and to find alternative routes when its path is blocked. Some of the best robotic mowers have more advanced sensors that detect obstructions sooner and plot a mowing plan, thus they don’t get stuck.

k. Connectivity

app controlled robot mowerNot all robot mowers are connected. If you want to control your mower remotely, be sure to keep an eye out for a product that offers connectivity and a smartphone app. Otherwise, you will have to go out to your robotic mower if you want to make any changes to your existing installation and set up.

l. Security

Many robot mowers feature standard security measures such as a PIN code. This code has to be entered when your mower is disrupted. It is an effective deterrent for thieves as stealing your robot mower renders it unusable. Some robotic lawnmowers also sound an alarm if they are lifted up for several seconds.

If your mower is connected, you may also be able to follow it via its GPS trace in its app. Since the best robotic mowers are expensive and remain outdoors for much of the year, additional security measures are well worth considering when making your purchase.

m. Noise Level

Lastly, check the decibel of your robot mower prior to purchase. This will not only keep your neighbours happy, but it will also allow you to set up your mower to work at night or early in the morning when you’re less likely to want to take advantage of your garden.

Final Thoughts

a lawn robot at workAll of the robotic lawn mowers we have seen make undoubtedly great choices. But if you are still unsure which mower to go for, we recommend the Flymo 1200 Rour editor’s choice.

Suitable for lawns up to 400 metres square, this model is the best robotic lawn mower – thanks to its self-charging system, quiet operation and adjustable cutting height. So, not only can you get your lawn looking pristine, but you also won’t have to worry about disturbing your household!

Furthermore, the Flymo 1200 R is suitable for gardens with slopes of up to 25% and features an effective obstacle avoidance system. Thus, you can rest assured there’ll be no accidents. After considering this robot lawnmower review, we’re sure you’ll agree that this is a great, easy-to-use mower for keeping an average-sized garden looking its absolute best.
