Full review of the WORX Landroid M WR140 Robotic Lawn Mower

WORX WR140 Landroid M 20V Robotic Lawn Mower

WORX is one of the leading brands for garden and outdoor power equipment. For over a decade now, this brand has been waxing stronger with an impressive number of useful and high-quality tools, and the best part is that their products are very budget-friendly. 

WORX launched the latest model of WR140 Landroid M in the spring of 2019. Ever since this robotic lawn mower has come to be one of the top sellers for 2020. And here’s why. 

Landroid is a smart machine built to operate autonomously, it automates the lawn mowing and maintenance process. WR140 is designed to work on a relatively small lawn of quarter-acre without human assistance. 

This robot lawn mower weighs 21 pounds and has three wheels; a single front wheel and two 8-inch rear wheels for excellent traction. With these wheels it’s able to handle both flat, tough terrains and slopes of up to 20o. And with a floating deck design it’s able to travel through slopes and hilly lawns without striping off the surface of the lawn. 

Landriod uses three cutting blades attached to a spinning disc to cut and mulch grasses. At the top of this robotic mower is a hatch that opens to reveal a 9-button control panel with a 2.5-inch LCD and a red Stop button. At the rear you’ll find a cover that encloses the battery compartment.

The robotic mower is also equipped with rain sensors and it’s able to detect changes in the weather to know when rain is coming. If the WR140 is already working and senses rain, it’ll head back to its docking station to wait out the rain. 

The default Rain Delay time is 180 minutes but you can change this setting time via Landroid App or using the control panel. It is best to allow the grasses to dry properly before sending out your mower because the Landriod doesn’t do well on wet grass. 

It is also able to sense objects and obstacles on its path, thanks to the Anti-Collision System (ACS). When it senses an obstacle, it turns to a different direction to avoid a head-on collision and if it accidentally bumps into something it draws back and  continues in another direction. You can also get the digital fence which you can use to cordon off trees and flower beds in your lawn, creating small islands that the robot will avoid.

The Landriod also has a number of safety features to prevent accidents. For instance, it knows when it’s lifted off the ground and it immediately stops rotating its blade disc in response to this, this way it prevents a terrible accident.

WORX Landriod also learns the layout of your lawn and becomes familiar with it. Depending on the size of your lawn, it creates a schedule for properly maintaining it. Of course you can adjust this schedule if you like. 

To prevent it from theft, WR140 is protected by a PIN code which you can easily set up on the WORX Landroid app. You can monitor your Landroid or lock it through the smartphone app.

How The WORX Landroid Works 

Once the Landroid is installed on your lawn, getting it to work is very simple and straightforward. You can either operate it through the control panel or use the smartphone app. The control panel is very intuitive but the WORX Landroid app is even easier. 

Once you input the details of your lawn, the mower will automatically create a mowing schedule for it but you can adjust this setting. Landriod leaves its charging base when it’s time to mow, and following the guidance of the installed perimeter wire, it cuts and mulches the grasses on your lawn while scattering the grass clipping on the lawn to provide nourishment to the lawn.

It works for almost 2 hours before heading back to the charging base for a recharge, its charging time is 90 minutes. With a full battery, the Landriod will automatically resume mowing till the job is complete, then it travels back to the docking station to wait for the next schedule. 

WORX Landriod also takes care of your lawn edges, once a week (usually on Mondays), it mows the grass along the edges of your lawn. This robot mower is programmed to trim this way by WORX but you can change this setting and program it cut edges more than once a week via the mobile app or the control panel. 

Normally robot lawn mowers leave a string of grass at the edges of the lawn which you’ll have to manually trim, but with this edge maintenance you’ll have very little or no trimming to do. Although the Landroid is built to be 100% waterproof, it doesn’t do too well on wet grass and the cutting result is less than excellent.  

WORX Landroid M Performance

The Landriod is an excellent automatic mowing machine. Landriod starts at one edge and mows in a straight line until it’s stopped by the boundary wire marking another edge, then it dutifully turns around and continues in a different direction. 

As it mows, it mulches the grass into tiny clipping and scatters them on the lawn. Once or twice a week (actually this depends on how to set it), it mows along the perimeter wire to give your lawn well-trimmed edges.

It does a great job of keeping a lawn neat and well-trimmed, but it comes with its flaws, which isn’t a surprise. Occasionally, the boundary wire fails to stop it and the robot mower slips out of the lawn. When this happens, the Landriod will need to be rescued and placed back on the lawn. 

Also, if your lawn is uneven with holes or tight spots, this may create navigation difficulties for the Landroid because it may get stuck in them. Although the Landroid can wiggle itself out of holes and tight spots by spinning its wheels in different directions, if this fails expect to get a notification on your smartphone app to come rescue the robot. On average, you may have to rescue it once a week. 

The WORX Landroid app creates a daily mowing schedule to suit the size of your lawn, but you can adjust this to what you think is best. On a full charge, the Landriod will mow for about 1.5 to 2 hours before heading back to the charging station for a recharge. Overall, this robot lawn mower does an excellent cutting job and will keep your lawn neat and well trimmed.

Ease Of Set-up And Use

Installing the WORX Landroid robotic lawn mower on your lawn is pretty straightforward if you have a simple lawn, but it can be complicated and difficult with a complex lawn. 

The actual amount of time you’ll spend installing this lawn mower on your lawn will depend on the size and complexity of your lawn, nevertheless, except to spend between 3 to 5 hours doing this and be prepared to get your hands dirty. 

You may want to hire a WORX professional to handle the installation and nicely set up your Landroid, but the setup process isn’t really as difficult as it seems. Anyone with little or no technical skills can do it, it only requires that you be careful and patient. 

WORX WR140 Landroid M 20V Robotic Lawn Mower

The Landroid comes with a user’s manual containing step-by-step instructions on how to properly lay down the perimeter wire and wire ground pins or pegs for keeping the perimeter wire in place. 

Before placing the perimeter wire, first analyze your lawn to determine where and how best to place the wire. If your lawn has areas you’ll like to freeze off like flower beds and trees, you’ll need to take them into account and mark out how you can properly run the wire to isolate those areas. While doing the actual work you may need an extra pair of hands. 

WR140 Landroid M comes with 250 pegs (Wire Ground Pins) for pinning down the perimeter wire and holding it in place. WORX recommends that you first use these pins to peg down the perimeter wire and run a test mowing cycle before proceeding to bury it no more than a few centimeters below ground level. 

Installing the charging station is also not difficult and while choosing the ideal location for it, keep the following in mind. First, the charging dock should be placed on a flat land and a shedded place to prevent the batteries from overheating. Second, it needs to be at most 32 feet away from an AC mains power outlet.

To make installation and use as easy as possible, the following materials are included in the WR140 package; 180m (590ft) perimeter wire, 1 charging base, 8 lawn screws to secure the charging base, 2 wire repair connectors, 1 boundary wire distance gauge, 1 20V 4.0Ah battery, 3 spare blade kits, a user’s guide with detailed instructions, etc. 

After installing your robotic  mower, you’ll also need to download the WORX Landroid app from the play store to keep you connected to your Landroid from anywhere.


If you want a simple gadget to keep your lawn well-trimmed and tidy all year round, you can trust WORX Landriod to get the job. This brand is focused on quality, and with the Landriod the case is no different. 

WORX Landroid are pretty reliable machines and backed by a 3-year warranty. Other than occasional slip offs from the boundary wires and getting stuck in tight spots, you can expect it to live up to its advertised features. With proper maintenance, your Landroid may outlive your expectation.  

Ongoing Maintenance 

To keep your gadgets running smoothly for as long as possible you need to properly take care of it, this is a no brainer and the Landroid is no different. Landroid needs to stay in great shape to perform at its peak. 

To keep this robot in top shape you need to make sure it’s neat by periodically removing grass clippings and debris from the body, wheels and cutting deck. This is to prevent a build up of grass and debris. It’s important to also remove grass clippings and debris from contact pins and charge strips. 

What is the cost of a robotic lawn mower?

To maintain a neatly cut lawn, the blades of your Landriod need to always stay very sharp. Check the blades at least once a month to make sure they’re still very sharp and replace them when necessary. When the blades will need replacement depends on how big or small your lawn is and how often you mow. 

As a guide, WORX recommends that the blades of your Landroid be replaced every 4 months, thankfully this robomower comes with extra 9 replacement blades. 

The battery of your WORX Landroid also needs to be taken care of and before you start performing any maintenance like washing the wheels, chassis and cutting deck with spraying water and brush, remove the battery. The 20v Lithium Ion Battery that comes with WORX robotic lawn mowers can last between 3-5 years depending on usage. 

The Landroid has rain sensors and it’s weatherproof but in extreme weather conditions like a lightning storm, you’ll have to protect it by making sure it’s not charging. You also have to disconnect the boundary wire and unplug the charging base. 

Landroid also needs proper storage in the winter season. Clean up the Landroid, remove the battery and store it in the garage or dry place over the winter.  

What’s The Difference Between The WORX WR140 And WR150? 

Both the WORX WR140 (Landroid M) and WR150 (Landroid L) are WORX Landroid models. With these premium gadgets, WORX aims to take the hard work out of grass cutting and lawn maintenance. 

These robotic mowers have very similar designs and features including auto set-and-forget, edge cutting, useful mobile app, rain sensor, and GPS tracking. However, they are designed to handle different lawn sizes. WR150 is built to care of bigger lawns of up to 1/2 acre, while the WR140 is designed to handle smaller lawns of no more than 1/4 acre. 

The major difference between these two are seen in cutting height, cutting width and battery life. WR150 is a bigger robomower with the cutting width size of 9 inches, and adjustable cutting height levels of 1.6 to 3.9 inches. 

As the smaller robot, WR140’s cutting width size is 7 inches with adjustable cutting height levels of 1.9 to 3.5 inches. Between these two robots, WR150 is more suitable for heavy duty work and can better handle tougher and longer grasses.

Extra Purchases And Ongoing Costs 

All WORX Landriods, including the WR140, come as a complete package. Everything you need to set-up and install this robot comes with it, so you don’t need to purchase any extras before you can get it to work. 

Installing the WR140 may cost you some extra bucks if you decide to hire a WORX professional to do it for you. But since this robot comes with a user’s manual with very detailed instructions, anyone with basic technical skills can set it up.

The Landriod also comes with replacement parts like blades, and a battery with an average lifespan of 3-5 years. With all these, properly maintaining your robot mower shouldn’t cost more than $20 in a year.

WORX vs Husqvarna

WORX and Husqvarna are among the biggest brands in outdoors and garden equipment, including robot lawn mowers. Husqvarna is a Swedish company that has been in the business of manufacturing outdoor power equipment for over 3 centuries now. 

For over 300 years, Husqvarna has built and maintained a solid reputation in the garden and power equipment niche, and impressively they haven’t lost their touch. Husqvarna is currently the brand with the highest number of robotic lawn mowers on sale, about 7 of them. 

Compared to Husqvarna, WORX is relatively new in the business of making tools and garden equipment. But, over the last decade, they have managed to build quite an impressive reputation for themselves, especially with electric trimmers, chainsaws, cordless electric lawn mowers and robotic lawn mowers. 

Robotic lawn mowers from WORX are pretty advanced machines with smart features like GPS tracking, rain sensors, anti-collision system, user-friendly mobile apps, etc. They also look pretty good and get the job done.


What is the lowest cutting height and is it adjustable?

WR140 can cut grasses to as low as 1.9 inches. You can adjust the cutting height from 1.9 to 3.5 inches with 0.4 inches difference between each height setting. When using the Landroid for the first time on your lawn, WORX recommends that you start with the highest height setting and gradually work your way to the lowest, especially if the grasses on your lawn are a little grown.

How does the Landroid handle obstacles?

Landroid handles different obstacles differently. When it encounters small objects like toys, sticks or dog poop, it runs over them. But with bigger objects like a tree branch, it will either bump into the branch and turn around or sense the branch and go around it. 

To detect obstacles, the Landriod uses an Anti-Collision System (ASC), but this comes as an add-on and not integrated into the robot. The ASC helps detect obstacles and navigate better via ultrasonic detection. 

Before sending your robot mower to work on your lawn, it’s important to first prepare the lawn by making it objects and obstacles-free because objects on the lawn can disrupt the lawn mower. Small objects like toys can get caught in the cutting disc while obstacles like tree branches may trap the robot.

What slope can the WORX Landroid M handle?

The M WR140 doesn’t do well with too much inclination and steep slopes. It can only handle up to a 35% incline or 20° slope. A very hilly lawn or sloping landscape will cause navigational troubles for the WR140.

What do you do for winter care?

Caring for your Landriod during winter is very important to think about. Unfriendly weather conditions like deep snow can cause a lot of damage to the robot. 

To put it into winter storage, it is best to clean off all grass clippings and dirt on your Landriod, remove the battery and store it in a frost-free place until spring or your next cutting season. 

Can it cut grass when it’s raining?

WR140 isn’t built to work in the rain and it doesn’t handle wet grasses well. Landroid has rain sensors that help it detect rain and return to its charging base until the weather is clearer and much drier. 

If it starts to rain just before a scheduled mowing time, the Landriod will delay the mowing cycle and send a notification to your smartphone app. It’s important to always schedule your Landriod to work in clear and dry weather to avoid any weather-induced damage.

Final Thoughts on the WR140 Robotic Lawn Mower

When it comes to gardening and outdoor power tools, you can always trust WORX to deliver the best both in quality and affordability. 

For over a decade now, WORX has built a solid reputation in manufacturing and marketing top best-selling lawn and garden equipment. And this is no different with robotic lawn mowers. 

So should you invest in a robotic lawn mower? If you’d rather spend your time on things more important than lawn mowing, then it’s a big YES. 

And should you invest in a WORX Landroid robotic lawn mower? Well, if you are looking for a great value robotic lawn mower for lawns that are a quarter acre or less, we hope that this WORX Landroid review has helped you realize that the Landroid M is probably your answer.
