No remote control.

When I reviewed the Worx Landroid M Cordless Lawn Mower (WG794) last year, I gave it high marks for its cutting performance, ease of use, and quiet operation, but it lacked wireless connectivity and mobile app control capabilities. Worx has since discontinued this model and replaced it with a $999.99 Landroid M 20V Cordless Robotic Lawn Mower (WR140). This version also provides excellent cutting performance, is easy to program, and is whisper-quiet. It comes with GPS and Wi-Fi radios and works with an easy-to-use mobile app, all of which earns it our Editors’ Choice for robotic lawn mowers.

Design and Features

The WR140 features the same black and orange color scheme as its predecessor and uses the same floating deck design that allows it to travel up hills and slopes without disrupting your garden. It has two 8-inch rear wheels, one front wheel, measures 10 x 15 x 22 inches (HWD), and weighs 21 pounds.

It uses a rotating disc with three rotating cutting blades to provide a relatively narrow 7-inch cutting width, but that’s because this model is designed for smaller lawns (a quarter acre). If you have a large lawn, the L 20V (opens in a new window) ($1199.99) can handle half an acre. The cutting height ranges from 1.5 to 3.1 inches and can be adjusted using the large circular dial on the top of the mower. The rear has a lid that lifts up to reveal the battery compartment, a USB port (for a firmware update), and a compartment for the Find My Landroid unit that adds GPS capabilities to the mower. There are two charging blades on the right side of the mower that connect to the charging blade at the base station when the mower is parked at home.

The M 20V is powered by a 20V/4.0Ah rechargeable battery. It can be removed and used in Worx 20V cordless power tools such as hedge cutters, edging, and weed removers. Under the hood are twin brushless electric motors with a maximum sound rating of 63 dB. It’s a little louder than the Honda Miimo HRM 310 (58 dB) and Husqvarna 315X (58 dB), but it’s still very quiet and can run at night without disturbing anyone. There’s also a 2.4GHz Wi-Fi radio under the hood that connects the mower to your home network.

At the top of the mower is a nine-button control panel with a 2.5-inch LCD screen, along with a large red stop button that instantly turns the mower off, a rain sensor, and an ACS (Anti-Collision System) hatch. The ACS Module ($249.99) is an optional accessory that uses ultrasonic detection to help navigate around trees, outdoor furniture, and other obstacles. The LCD screen displays the current time and date, has indicators for Wi-Fi signal strength and battery level, and will tell you the percentage of work done in real time. Use the buttons to navigate menus where you can create a mowing schedule based on the size of your garden, select work areas, configure Wi-Fi settings, and rain delay settings. can be configured.

While the control panel is easy to use, the mobile app is easier and more convenient because you can adjust settings from anywhere using your phone. It opens on the home screen with a picture of the mower, its name, and the current battery level. There are buttons on the RadioLink, Find My Landroid, ACS and Off Limits mowers. RadioLink is a soon-to-be-released wireless communications module that will extend the mower’s Wi-Fi range, and Off Limits uses magnetic strips to create mowing areas without placing a weed wire. Pressing any of these buttons activates the feature and, in the case of Find My Landroid, takes you to a screen where you can set up a geofence around your garden. If the mower leaves the circle, you can track its real-time location on the satellite map.

At the bottom of the main screen there is a bar that tells you the current status of the mower such as mowing, charging, home and fault. Below the bar are buttons to stop and restart the mower and send it home to its charging dock. Press the three bar button in the upper left corner of the screen to create a table. You can also view usage stats including total distance traveled, uptime and toll count, you can update firmware, configure Wi-Fi settings and receive push alerts. You can enable/disable which tells you the status of the mower including when it has returned. Home (depending on it), when there’s a delay in rain, when it’s charging, and when it’s stuck or has traveled out of range. The only thing missing in this app is the ability to use your phone as a remote control to control the movement of the mower like you can with the Robomow RC306.

The box includes a mower and charging base, a Find My Landroid unit, a power supply, 250 wire clips, a 590-foot spool of circumferential wire, a distance meter, a ruler, batteries, various screw connectors and wires. . The WR140 comes with a three-year warranty.

Installation and Performance

Installing the WR140 for the first time isn’t difficult, but setting the tire wire can be time consuming and requires a fair amount of physical labor with a lot of time spent on your hands and knees hammering into the ground. It took me a few hours to hook up my 1950 sq ft railing and secure and connect the base station. Fortunately, Worx provides step-by-step installation instructions that make the task very easy.

Once I installed the surrounding wire and turned on the charging base, I placed the mower on the base to charge it. I Installed the mobile app, created an account, and followed the app’s instructions to scan the QR code under the battery cover. Using the router’s control panel, I scrolled down to Setup Wi-Fi, turned on SmartLink, and selected my Home Wi-Fi SSID. I entered my password and within 30 seconds the mower was connected.

Once connected, I clicked the Find My Landroid button in the app to install the Find My Landroid module. It requires a firmware update, which was sent to my email address. I Installed the update to a FAT32 thumb drive and followed the application walkthrough to turn off the router, insert the drive into the USB slot on the back of the router, and wait for the firmware update (about 20 seconds). Next, I removed the unit cover and connected the data cable to the unit. I inserted the unit into the bore, replaced the cap, and placed the mower in its charging base. I turned on the engine and got a message in the app that the sim will take about 30 minutes to update (you can continue to use the engine while the sim is updating). However, after five minutes, the app informed me that the update was complete and instructed me to secure the unit cover with two screws.

The Landroid M excelled in the test. I let him create a schedule based on the size of my lawn using a lawn calculator and keep track of it without a problem, requiring less than three hours to cover my lawn. I kept cutting height to a minimum, and the mower kept clean and well trimmed lawn. The Cut-to-Edge feature had no trouble trimming the edges of my lawn, and the blades did a good job cutting grass clippings into good mulch. The motor was very quiet and the rain sensor did its job, delaying the scheduled cycle after a heavy rain and restarting it after three hours (the time you specified in the rain delay setting).

I received push alerts when the mower was charging, returning to its base, cutting boundaries, and when there was a delay in the rain. I also got warnings when I walked outside the wireframe, a problem that occurred in one spot on my lawn where I put the wire too close to the driveway. As soon as I changed the wire, the cutter did not twist again.

I tested the Find My LandRide GPS radio by putting a mower in my truck and driving a few blocks away. Sure enough, the map showed the exact location of the mower on the street tucked away in the hooded bed of my truck.


As with every robotic lawn mower we’ve reviewed, the Worx Landroid M 20V Cordless Robotic Lawn Mower (WR140) isn’t cheap, but like its predecessor, it’s one of the least expensive models and it’s cutting edge. It works better. Mow your lawn. And this time, it has GPS and Wi-Fi radios and works with a smartphone app that lets you control it from anywhere. In addition to starting and stopping the mower and adjusting mowing schedules, the app allows you to monitor the progress of the mower and send you status alerts letting you know what you’re doing right now. If that was and if there was any problem. It will even tell you where the mower is in case someone decides to free it from your property. It would be nice if the app offered a remote control so you could operate the mower yourself, but it’s a minor problem and doesn’t stop the Worx Landroid M WR140 from earning Editors’ Choice.
