Here’s our 2022 review of the Worx WR140 Landroid, one of the best robotic lawn mowers on the market

Our rating: 9.7
Price: Low

You’re going to be the envy of the neighborhood with the Worx WR140 Landroid because it’s an exceptional grass-cutting machine. Maybe you’re old enough to remember when Roombas, the carpet cleaning machines, first came out.

Did it feel like you were suddenly transported into a Jetsons-like future? Well, the Landroid is the same kind of thing, only for your yard. When you’re the proud owner of one, you’ll be able to take back your weekends so you can sip an ice-cold beer while watching your bot cut your grass. Robotic mowers are now a glorious reality, and the Landroid is one of the most innovative robotic lawnmowers on the market.

  • Versatile battery powers other Worx devices;
  • Patented anti-collision system;
  • GPS module prevents theft;
  • Customized mowing schedules;
  • Gets closer to edges than other robotic mowers;
  • Perfect for lawns up to ¼ acre.



Easy to Set Up

Simply set up the charging base, lay down the boundary wire, measure your lawn with the app, and you’re good to go. It’s easy to do it yourself, and the entire process takes three to five hours at most. However, after setting up your boundary wire, you might need to spend a couple of weeks tweaking the system until it works at an optimal level.


With the super convenient mobile app, you can control Landroid from the palm of your hand. The app becomes command central for all lawnmower functions. You can check mowing progress, keep your software up to date, and a few other things too.

One Battery Many Devices

Worx Power Share means you can use the same battery for all your tools (that is if they’re manufactured by Worx). This gives the machine a versatility other mowers don’t have.

Exceptional Navigation Abilities

Each wheel is driven by an independent brushless motor. This provides the unit with better maneuverability. You can choose to get the module with a patented anti-collision system that uses ultrasonic sensors so that Landroid stops, backs up, and reroutes when it encounters an obstacle. If your Landroid encounters an impediment to its journey, it will simply back up and reroute.

Worx WR140 handles slopes up to 20 degrees.

To exclude certain obstructions from its itinerary, purchase the “Off Limits” digital fencing module. This module uses magnetic strips to create no-mow areas without having to lay down perimeter line. The robot can handle slopes up to 20 degrees. It’s been specially engineered to navigate the narrow passageways other robotic lawnmowers can’t handle. Keep in mind that it’s a slow mower, moving about one mile per hour while cutting a path seven to eight inches wide.

The Landroid excels at getting itself out of tight spots, including corners, uneven terrain, and holes. It’s mesmerizing to watch the bot use its proprietary algorithms to figure out the best way to extricate itself.

If all else fails, the unit will send you a notification that it’s trapped. The Landroid can calculate the size and shape of your lawn. By walking the perimeter of your yard with your smartphone, the bot learns these parameters. This way, it’s able to calculate the most efficient cutting path.

Customized Mowing Schedules

I love how the unit can create customized mowing schedules. You can have your automatic greens keeper mow everyday or every other day. You can even have it recommend a schedule based on your lawn’s size and conditions.

If you decide to go with this option, the app will create a schedule based on your lawn size and how frequently you want the unit to operate. For example, suppose you’d like a frequency of every day. In that case, it’ll calculate how many minutes it should run to accomplish the objective.

You’ll no longer need to worry about setting time aside on the weekend to mow your lawn! Simply schedule your mowing on the easy-to-use app, and your Landroid will do the rest.

Two Hours on a Single Charge

The unit can operate for one and a half to two hours on a single charge. When the battery gets low, the unit is smart enough to head back to its charging base. It takes approximately 90 minutes to recharge the battery, after which the bot will resume where it left off.

Rain Sensor

If you don’t want your bot to cut grass during a torrential downpour, you can activate the rain sensor. This way, it returns to the charger port to wait out the storm. Keep in mind that the unit has a rain-resistant shell. This means the chances of rain damage are minimal even if you have it mow when heavy precipitation drops are falling from the sky. However, it’s best to let the grass dry out because this mower does better in those kinds of conditions.

There’s a rain delay setting so that your bot will automatically restart after a heavy downpour. The default rain delay time is 180 minutes. You can change this time via the Landroid app or by using the control panel.

Gets Closer to the Edge

Worx WR140 Landroid gets closer to edges than most other robotic mowers.

The three-blade cutting disc gets closer to edges than most other robotic mowers. This means you’ll have less trimming to do later. Landroid cuts more frequently than you’d do with a manual lawnmower, taking a little off the top during each mowing cycle. Like all robotic lawnmowers, the Landroid mulches your grass into tiny pieces. These cuttings are excellent natural fertilizer for your lawn.

Three rotating blades provide a relatively narrow seven-inch cutting width. This might not seem like much, but it’s perfect for ¼ inch lawns (the size the unit was built for). You must change the blades every 200 hours of operation. The blades are held on with screws and are easy to switch out. You get two sets of replacements when you buy the Landroid.

Anti-Theft and Safety Features

Optional anti-theft and safety accessories for the WR140

You can purchase the optional GPS module, an anti-theft feature that locks down your unit if it’s ever removed from its mowing perimeter. This feature is called “Find My Landroid”, and allows you to track your mower’s location in real-time on a satellite map.

This is highly recommended because if your device is stolen, you’ll be able to track it down wherever in the world it is. To prevent unauthorized use, you can choose a unique pin code. This code will need to be entered before anyone uses the Landroid.

The blades stop turning when the mower is lifted. This means that children can’t injure themselves on it.

Quiet Operation

While the Landroid isn’t the quietest robotic lawnmower, it’s barely audible at 63dB. This is about the same auditory level as the human voice.

Saves You Money

If the unit lasts for three years (and there’s no reason why it shouldn’t), your groundskeeping costs will only be about $1 a day. That’s cheap when compared to hiring a lawn service guy and will save you thousands of dollars over the unit’s life.

Floating Deck Design

Landroid WR140 allows to configure how high your lawn should be

Don’t you hate when in the middle of your mowing, your machine takes a big chunk out of your beautiful lawn? With the Landroid, that’ll never happen. That’s because the unit has a floating deck design to prevent this from occurring.

Choice of Three Cutting Heights

With the choice of three cutting heights ranging from one and a half to three inches, you get to decide how high you want your lawn to be. Adjusting the height is as simple as turning a dial.



When you buy the Landroid, you’re not entirely finished with weed whacking and lawn trimming. That’s because the machine can’t get to the edges of your lawn. This means you’re going to need to do edge trimming every couple of weeks or so.

Unfortunately, you won’t be able to connect the unit to your smart home network. This integration will have to wait for future iterations of the product.

In rare case the Worx Landroid could drive over the boundary wire.

A few users complain that the Landroid spends too much time on one area of their yard to the exclusion of other areas. Some people have had the inexplicable experience of the Landroid driving over the boundary wire so that it suddenly finds itself outside the established perimeter. The good news is that you should receive a notification on your phone when it needs rescuing.

Some buyers report that they get notifications that their unit is stuck. However, when they go to rescue their greens keeping bot, they find out it was a false alarm. This means they waste time walking over to the device to press the sequence of buttons that will get the unit rolling again.

However, some people complain that the mower can get stuck without sending a notification that it needs assistance. These users say that when this happens, the bot will continue operating until all the juice is extracted from the battery. A few people have had bad luck with the batteries, having them die every couple of months or so. When the battery dies, there’s no alert.

The optional Landroid garage for the weather-resistant but non-waterproof WR140

If your lawn has a complex configuration, you’re probably going to need to buy extra wire and stakes. That’s because the wire and stakes that come with the unit are for a simple layout. Some customers say that if you lay the wire on top of the ground instead of burying it, the machine can slice the wire in half.

Although the Landroid is weather-resistant, it isn’t waterproof. The best way to protect your machine from the elements is with the optional Landroid garage. A deck or patio the charging unit can sit under is another option.


Worx WR150 is an alternative model for bigger yards.

The Worx WR150 offers many of the same features as the WR140. The design is quite similar, with just a few minor differences. If your lawn is bigger than ¼ acre, both the WR150 and WR153 come with nine-inch blades and can cut yards that are ½ acre in size. Also, the cutting height on the WR150 can be adjusted up to four inches instead of three.

The “Find My Landroid” GPS module is included with the WR143. With the WR140 and WR150, this module must be purchased separately.

Final Verdict

The Landroid Worx WR140 is the perfect amalgamation of sleek design and functionality. When you purchase one, you’ll wonder how you ever got through life without having a robotic lawnmower this exceptional at your beck and call. That’s why I highly recommend this unit to everyone who wants to lighten their homeowner’s chores.
