Worx WR142E M700 Landroid
Robotic Lawnmower Review (2020)


Worx WR142E M700 Landroid is meant for lawns up to 700 m² (or 0.17 ac.) that has slopes no steeper than 20° (or 35 percent). It’s otherwise an autonomous robot lawnmower using a 20V 4 Ah lithium-ion rechargeable battery and running on electric power. It’s got 3 pivoting razor-like blades underneath the mower mulching grass fairly quietly (up to 67 dB) and maintaining your lawn at a cutting height of 30-60 mm (or 1.18″ to 2.36″).

Apart from that, this mower is making use of cloud computing AI (AIA technology) to optimize the mowing pattern, mowing scheduling, and so on, over time automatically when it’s connected to the internet over Wi-Fi. Also, by using the Worx Landroid app, you can control things remotely as well. It’s got all the essential mowing, safety, and security features by default, and offers additional features for extra cost. Also, the mower comes with a warranty of up to 3 years.

You can forget about disturbing the peace and quiet in your neighborhood during the weekends once you’ve gotten yourself a robot lawn mower. Instead you’ll have more free time to do better things with your free time rather than mow the lawn manually.


Quick Overview for the Hasty

Worx WR142E M700 measures 55.8 cm x 40.4 cm x 20.5 cm / 22″ x 15.9″ x 8.1″ (length x width x height) and weighs 9.2 kg (or 20.28 lbs).

If you’re new to robot lawn mowers, quickly skim over this “Robot Lawnmower Buying Guide” for a better overview on the matter.

At base value, Worx WR142E M700 features rain, tilt, lift, and collision sensors similarly to your typical robot lawn mower. What makes this robot mower stand out is its “cut to edge” feature which allows it to cut closer to the edges, leaving you with even less work. Additionally, if you were able to connect the mower to the internet over Wi-Fi, two more features come available. Not only will the mower make use of the cloud computing AI (AIA technology) to improve its working efficiency, you also get remote control with more settings via the Worx Landroid app.

For extra cost you can buy upgrades (5) to it that include the 1) Anti Collision System (ACS), an ultrasonic sensor for detecting obstacles from afar in order to drive around them without touching, but also the 2) Off Limits Module, 3) Radio Link Module, 4) Find My Landroid Module, and 5) Voice Control. More on those things further into the review.


Who’s Behind Worx WR142E M700 Landroid?

Worx is a brand name for the Western markets which is owned by Positec Tool Corporation, a China-based manufacturer of power tools, lawn and garden equipment and accessories.


Ultimately then, it’s Positec that does the producing and Worx that does the selling of this Worx WR142E M700 Landroid robotic lawnmower.

They stand out by offering unique solutions – Worx robot mowers for example are customizable/upgradeable and smarter when compared to most competitor robot mowers.

1) General Features

Automatic charging and mowing cycle 
Every robot mower today is more or less fully autonomous, meaning they will go from mowing to recharging to mowing again and again automatically. Same thing with this Worx WR142E M700 Landroid robot lawn mower, but over time it will even automate the mowing schedule and some other things, making thing even more automated.


Silent operation (up to 67 dB) 
It keeps your lawn in check quietly, sound levels going up to 67 dB only. Compared to a regular lawn mower sound levels which can reach 110 dB, the robot mowers sound level is comparable to a normal conversation. You can read more here: “How Loud Are Robot Mowers?

Wi-Fi enabled 
Worx WR142E M700 Landroid can be connected to the internet via Wi-Fi. This allows the mower to access the cloud computing AI (AIA technology), but also pair with a smart device (phone, tablet, etc) using Worx Landroid app (Positec) for remote control.

USB port 
Located at the back of the mower is a USB port for updating its firmware in case you couldn’t do that via the over-air connection.

Low running costs 
Apart from the initial purchase, there are also the running costs involved. Electricity and certain replacement parts factor into it. The battery (roughly $90) will last anywhere from 2 to 6 years while the blades (around or less than $1 per blade) need changing roughly twice per mowing season (3 at a time). When it comes to electricity, a 20 volt 4 Ah battery uses roughly 0.08 kWh (calculated here). That’d be roughly 10 cents a day and up to a few dozen bucks per mowing season.


2) Control System

Control panel keypad 
At the top of the robot mower is a manual control panel with some buttons and a screen for feedback. It’s all out in the open, but is somewhat water resistant, so it shouldn’t really be a problem. You get more control options when using the app.

Worx WR142E M700 Control Panel

Worx Landroid App (PositecDev) 
When you cover the mowing area with a Wi-Fi signal and pair the mower with the app “Worx Landroid App (Positec)”, you get remote control over the robot mower. Instructions for pairing it are there in the manual, but it goes something like this: first bring the robot mower into the same Wi-Fi signal you’re using the smart device with. Then you install the app, create an account, allow camera access and scan the robot mower’s QR code found underneath the cover. Once that is done you simply insert the Wi-Fi password into the interface and follow the final instructions for pairing the device with the mower using the Wi-Fi connection.

Now you can start receiving alert messages through the app informing you of incidents related to the mower, giving you more feedback of what the robot needs or what’s wrong with it, etc, but also gain access to more settings and options in general.


3) Navigation System

Mowing pattern: random 
Worx WR142E M700 Landroid mows in a random pattern. If connected to Wi-Fi, it will make use of the AIA technology (cloud computing AI) to optimize the mowing schedule and route to better fit with your garden layout, grass growth rate, and other factors, over time. The way the mowing pattern looks like is once it comes in contact with an obstacle or reaches the perimeter wire, it will turn and start mowing in a different direction.

Worx WR142E M700 Moving Pattern

Relies on a perimeter wire 
Most robot mower rely on a boundary wire to work, and so does Worx WR142E M700. It’s an electrified wire (not harmful) that defines the cutting area and helps the mower find the recharging station. The wire makes a loop and is connected to the charging station. You can install it both ways: under the soil or tightly placed against the grass (the grass grows over it over time), but burying it is better in the long run (but not too deep). The installation will take some time, but it’s well worth the effort. Additionally, the clearance or the distance between the wires going through a narrow passage should be about 90 centimeters (or 3 feet). If it’s just one wire going through the narrow passage, the passage should be wide enough to allow the robot mower to physically fit through.

multi-zone feature 
You already know that this Worx Landroid can have up to 4 configurable zones at a time, but how does it work? Since it’s not using GPS to define those areas, they’re defined by exit points from the perimeter wire you yourself can set instead. The way the zones work is you start the process and the mower starts following the perimeter wire out of the charging station until you press the STOP button as the mower reaches the spot you want to mark as the 1st zone, the first exit point from following the wire. It’s got additional configurable settings to it, but that’s the general gist of it.

Collision sensor 
Not to confuse with the Anti Collision System (ACS) sensor you can buy for extra cost, the collision sensor is basically just a bump sensor. When it hits something, it will turn and mow in a different direction rather than pushing forward.

Rain sensor 
If enabled, when the robot mower detects rain, it will return to the charging station. Once there’s less humidity in the air, the mower will automatically start a “rain delay” countdown. This rain delay countdown is configurable.


4) Charging System

The recharging and mowing cycle is automatic. That means it will go out to mow the lawn and returns to recharge when it gets low on battery, after which it goes back out to mow again as per the schedule.

Worx WR142E M700 Recharging Station

Laterally mounted charging contacts 
While most robot mowers have the charging contacts located at the nose of the mower, Worx WR142E M700 has them on the side. While the frontal contacts require a robot mower to circle into them, Worx’s lateral charging contacts allow the mower to simply drive into the charging station from the side where it came from without needing to make any complicated maneuvers.

Stealthy recharging station
The charging station has holes at the base of it allowing grass to grow over it and virtually hide the charging station platform leaving only contacts stay visible. Most other robot mowers have a flat platform for a charging station that basically suffocate the grass underneath. Worx’s solution is simple yet unique and great.


5) Cutting System

Mulching system
All robot lawn mowers mulch grass, same deal with this Worx WR142E M700. Mulching means that the grass is not collected and instead, but more often, so that the small grass clippings fall back onto the soil and act as natural fertilizer making your lawn healthy. If you wanted a really healthy looking lawn, pretty much all that’s left to do is aeration.

Worx WR142E M700 Cutting System

Cut to edge feature
Worx WR142E M700 Landroid cutting blade system is not in the middle as is with most robot mowers. Instead, the rotating disc the blades are attached to is located closer to the side of the mower so that when it follows the perimeter wire, the outer edge of the lawn gets neatly cut. Cut to edge feature is when the mower makes a loop following the perimeter wire all the way around while cutting grass. This will happen automatically from time to time, but you can trigger this manually as well.

Cutting height adjustment feature
The cutting height can be adjusted manually between 4 levels of heights from 30-60 mm (or 1.18″ to 2.36″).

3 pivoting razor-like blades
There are 2 blades types robot mowers tend to have. One is a solid blade and the other a rotating disc with usually 3 pivoting razor-like blades attached to it.

Worx WR142E M700 Landroid Robotic Lawnmower uses the second type, the small pivoting blades. These are quietersafer, and more energy efficient when compared to the solid blade. The rotating disc will sometimes start turning in the other direction so as to lengthen the lifespan of the blades. At least that’s what I read, I haven’t checked so close down there myself. ^^ As for the negatives, the pivoting razor-like blades attached to a rotating disc are a little less efficient at cutting things when compared to the solid blade.

6) Safety Features

Emergency STOP button
Apart from Worx WR142E M700 having a big emergency STOP button, being fairly quiet (up to 67 dB)moving slowly, and having a considerably weaker motor when compared to your regular lawn mower, meaning it will have a hard time with anything other than grass, along with blades being small and tucked deep under the chassis, Worx WR142E M700 Landroid Robotic Lawnmower actually has a few more tricks under its belly (learn more: “Robotic Lawnmower Safety”).

Collision, tilt, & lift sensors
While the collision sensor’s main function is to aid navigating the lawn, it’s also a safety feature. Instead of the robot mower just pushing forward with the intent to tear down absolutely everything in its path, it will instead bump into it, realize there’s an obstacle, turn, and start mowing in a different direction. Tilt and lift sensors will bring the blades to a complete stop if the mower is tilted or lifted.


7) Security Features

Lock function 
The lock function does what it sounds like: locks up the robot mower until the correct PIN is entered. It becomes locked when you press the STOP button while it’s working, for example, or when it gets stuck or whatnot and stops working on its own, and so. It gets locked when lifted, but also when it loses the Wi-Fi signal for 3 days. It can be locked or unlocked via the app as well.

Pin code 
The default PIN code for this Worx WR142E M700 is “AAAA” on the keypad. This can be changed in the settings. Do note however that when you forget the PIN, you’re kind of screwed (read this: “In order to make Landroid as secure as possible, there is no reset procedure for the PIN that can be operated by anyone, including Landroid authorized service centers.”). So DO NOT forget the pin code!

The alarm most likely goes off after some time when it’s lifted whilst working and the PIN code is not entered. It’s a fairly loud one, too.


Additionally, you could:

Hide from bypassers
Try installing the charging station somewhere hidden from bypassers for added protection.

Use a sticker
You can custom make a sticker with fake information about its security features and put it on the mower for the potential thief to kindly return the mower once they notice it – once they realize that they can’t do anything with it without knowing the PIN code, instead of just leaving it somewhere, they might return it knowing they could still get off easy. They might…

Fake surveillance system
Putting a camera, even if fake, in an obvious easy to spot location overlooking the area will at least make the potential thief think twice.


8) Upgrade Features for Extra Cost

Off Limits module
To simplify excluding flowerbeds and the like from the cutting area without needing to drag out the perimeter wire, Worx has this Off Limits feature set offered for extra cost. It’s a magnetic strip you install around areas you don’t want Worx WR142E M700 Landroid to cut down. If the Off Limits module is plucked into the mower, this sensor can detect that magnetic strip and won’t cross it.

Worx WR142E M700 Off Limits

ACS (Anti Collision System) module
It’s an ultrasonic radar sensor that can detect obstacles in front of it and avoid collision entirely.

Worx WR142E M700 ACS

Voice Control
With this extra, when you push the big red button on the mower, it will ask you simple questions on what you want it to do next. Based on your voiced answers the robot mower starts doing its thing accordingly. Fairly basic.

Radio Link module
You get a Wi-Fi signal device and a receiver. The receiver plucks into the mower and the Radio Link device itself you connect to your internet modem/router even if it doesn’t have Wi-Fi by default. The Radio Link device creates a wifii-like signal between it and the receiver so that the mower has constant internet access.

What if you have no internet at all? What then?

Find My Landroid module
This thing provides Worx WR142E M700 Landroid with internet via its pre-paid sim card for 3 years and an annual fee after that without the need to have the Radio Link module or any sort of wi-fi or internet yourself. It also provides the mower with GPS signal, sort of an anti-theft feature.

Should You Buy the Worx WR142E M700 Landroid Robot Mower?

When looking at the options available, similarly to other Worx robot mowers, the WR142E M700 is also a very decent one, assuming your lawn wasn’t bigger than 700 m² (or 0.17 ac.) and its features & price were right for you. The seller is trustworthy and has a warranty in place.

Should You Buy the Worx WR142E M700 Landroid Robot Mower?

It might not be for you if your garden layout was simply just way too complex or the slopes steeper than 35% (or 20°) and you wanted cut height to be less than 30 mm (1.18″) or more than 60 mm (2.36″). Otherwise I don’t really see a reason against going with this one.

Worx gives you control in what features you want the mower to have while making sure all the essential is there by default. So it’s not like you’re forced to accept the upsell of the extra features, rather they truly are just supplementary as per your needs solving a problem.

Take for example the GPS Tracking module – in Finland, the chances of somebody actually stealing one is super low, so it’d be a worthless extra cost feature. Or the Radio Link Module, perhaps somebody didn’t have the option to buy a router with strong enough Wi-Fi signal, etc.

You can check its price here: Worx WR142E M700 Landroid.


How To Install the Worx WR142E M700 Landroid Robotic Lawnmower?

I’d like to say that it’s simple, which it actually is, but instead the initial installation can be time consuming (talking hours). The instructions manual should go over the installation process. If it doesn’t come with the package, you can always find it online with simple Google search.

How To Install the Worx WR142E M700 Landroid Robotic Lawnmower?

The installation is fairly simple and all the information is provided in the installations instructions. The main thing is to do with the planning and executing of the installation of perimeter wire around the cutting area. This will take some time (many hours). But trust me, it’ll be worth it once it’s all set and done. This little helper does the more mundane work for you while also keeping the lawn fairly healthy. The low yet fairly constant sound level keeps away moles, too, and makes kids learn to put away their toys rather than leave them wherever. What’s not to like?

Another thing is the charging station. Setting this up is fairly straight forward (check with installation guide), but I’d like to point out a few key things still. They’re mainly to do with the charging station placement requirements:

  • It must be close to a wall socket;
  • preferably under shade & cover;
  • install on a relatively flat surface outdoors;
  • install it somewhere out of sight from bypassers;
  • leave at least 80 cm of free space in front of the charging station;
  • lay at least 30 cm of perimeter wire straight out to the opposite side if it follows by a left turn. If the turn following the 30 cm exit path follows a right turn, there’s no need to leave at least 30 cm of straight perimeter wire.
Worx WR142E M700 Charging Station Placement
If the turn following the 30 cm exit path is a right turn instead of left then the straight wire doesn’t have to be 30 cm long.


How To Take Care of the Worx WR142E M700 Robotic Lawnmower?

As is with all robot lawn mowers, Worx WR142E M700 Landroid Robotic Lawnmower, too, requires very low maintenance:

  • clean regularly;
  • replace cutting blades when need be;
  • replace rechargeable battery when it seems almost dead;
  • install charging station in shaded area to protect the mower from the elements;
  • don’t forget to unplug the power supply connected to the charging station you left outside for winter;
  • when storing the robot mower itself, charge fully, turn off, clean, and place in dry indoor conditions, and avoid leaving in freezing temperature.



Worx WR142E M700 Landroid is perfect for large lawns up to 700 m² (or 0.17 ac.) in size and is able to cope with slopes up to 20° (or 35 percent). It’s an autonomous robot lawn mower that runs on electric power using a 20 V 4 Ah lithium-ion rechargeable battery. With its 3 pivoting razor-like blades it quietly (up to 67 dB) mulches grass and maintains your lawn at a cutting height of 30-60 mm (or 1.18″ to 2.36″).

It’s using artificial intelligence (AI) to determine the optimal route and mowing schedule. Additionally, with a smartphone, you can remotely control its settings rather than having to do it manually. It has all the essential mowing, safety, and security features, and offers additional features for extra cost.
