Worx Robot Lawn Mowers: Which Model Fits Your Yard Size?

Worx is well known for battery-powered yard tools, and its Landroid robot mowers have become one of the most talked-about ways to hand the weekly mowing job to a machine. The newest Landroid Vision Cloud models skip the old buried perimeter wire. Instead, they use satellite positioning corrected through the cloud, plus cameras, to know where the lawn ends and what obstacles to avoid.
The five mowers below share most of that technology and differ mainly in how much lawn they are rated for, from 1/4 acre to 1 acre, and in extras such as four-wheel drive, a closer-cutting edge blade and GPS theft tracking; the sixth product is a garage to shelter them.

Every mower here lists an 8.7-inch cutting width and a 3-year manufacturer warranty. A few terms appear in every listing, so here they are in plain words. RTK Cloud is a way of correcting satellite positioning so the mower knows where it is to within about a centimeter, without you installing an antenna in the yard; Worx says there are no extra cloud costs. V-SLAM uses the camera to keep track of position when trees or buildings block the satellite signal. Vision AI is the camera system that recognizes objects and lawn edges.

Best for: Quarter-acre lawns with wheel-clogging grass
Pros

- 3-year warranty listed
Cons

- Up to 1/4 acre only
The WORX Robot Lawn Mower for 1/4 Acre, model WO7144, is a Landroid Vision Cloud mower rated for lawns up to a quarter acre. Its listing names RTK Cloud positioning, automatic yard mapping, AI obstacle avoidance using a neural network running up to 10 trillion operations per second, unlimited mowing zones and no-go areas in the app, and V-SLAM navigation for shaded spots.
What sets it apart in the listing is a wheel brush that helps reduce grass build-up around the wheels, plus RadioLink, which extends Bluetooth and Wi-Fi so the mower stays in touch across the whole yard. It can mow in Parallel, Checkerboard, Diamond or Natural patterns. The listing gives a weight of 39.2 pounds and size of 22.7 by 18.1 by 11.3 inches.
This suits a small yard, especially one with damp or sticky grass that tends to clog wheels. One caution: the WA0828 garage later in this guide does not list WO7144 as compatible, so check before buying the two together. If your lawn is bigger than a quarter acre, move up to the WR320.
WORX Robot Lawn Mower 4WD (WR342) for Slopes and Rough Ground
The WORX Robot Lawn Mower 4WD, model WR342, is built for difficult yards up to half an acre. Four-wheel drive means all four wheels push, and the listing says it handles slopes up to 84%, roughly 40 degrees. A terrain-adaptive chassis keeps the wheels planted over bumps and raised borders, and true front-wheel steering helps it turn with less damage to the turf.
It shares the RTK Cloud, Vision AI mapping, obstacle avoidance, unlimited zones and V-SLAM features of the others. It adds a Cut-to-Zero offset blade that trims closer to fixed edges, and Find My Landroid, which uses GPS and cellular connectivity so you can locate the mower even when it is off, get alerts and lock it remotely. The listing does not give its weight.
This is the pick for hilly or uneven lawns where a two-wheel-drive mower would slip. For a flat half-acre, the WR320 covers the same area with fewer extras.
WORX Robot Lawn Mower for 1/4 Acre (WR310) for Small, Simple Lawns
The WORX Robot Lawn Mower for 1/4 Acre, model WR310, is the entry model of the Vision Cloud range for lawns up to a quarter acre. Its listing covers the core features: RTK Cloud accuracy with no antenna, automatic mapping, AI obstacle avoidance, unlimited zones and no-go areas in the app, V-SLAM in shade, cut-to-edge border cutting and four mowing patterns.
The listing does not mention RadioLink, wheel brushes, Cut-to-Zero or GPS tracking, and it does not give a weight. Dimensions are listed at 27.9 by 21.7 by 11.3 inches.
This suits a first-time robot mower owner with a small, fairly flat lawn and good Wi-Fi reach. If your yard is the same size but your router is far away, the WO7144’s RadioLink may help.
WORX Robot Lawn Mower for 1/2 Acre (WR320) for Mid-Size Lawns
The WORX Robot Lawn Mower for 1/2 Acre, model WR320, steps up to lawns up to half an acre. It is listed as two-wheel drive and weighs 44.5 pounds.
Along with the shared Vision Cloud features and four mowing patterns, its listing includes RadioLink for extended connectivity across larger lawns. It does not list the Cut-to-Zero blade or Find My Landroid tracking found on the WR340 and WR342.
This suits a typical suburban lot that is mostly flat. If your half-acre includes steep banks, the WR342 is the safer choice. Homeowners still mowing by hand and weighing a self-propelled lawn mower instead should consider how much weekly time a robot would save.
WORX Robot Lawn Mower for 1 Acre (WR340) for Large Yards
The WORX Robot Lawn Mower for 1 Acre, model WR340, has the largest rating here at up to one acre. It is listed as two-wheel drive and weighs 50 pounds.
It combines the shared Vision Cloud features and mowing patterns with the Cut-to-Zero offset blade for closer edges and Find My Landroid GPS and cellular tracking with remote lock. The listing does not mention RadioLink.
This suits large, mostly flat properties where security matters. For steep ground, the 4WD WR342 handles slopes better but is rated for half an acre.
WORX Robotic Lawn Mower Garage (WA0828) for Weather Protection
The WORX Robotic Lawn Mower Garage, model WA0828, is a shelter for Vision Cloud mowers. The listing says it protects against heat, heavy rain and strong winds, and the description adds snow and strong sun. It assembles with screws and comes in black.
The listed compatibility is WR310, WR310.1, WR320, WR320.1, WR340, WR341, WR342, WR344 and WR346. The WO7144 is not on the list. The listing gives dimensions of 19.55 by 5.46 by 28.59 inches, which look like boxed measurements.
This makes a good add-on gift for someone who already owns a compatible mower. Keeping any mower clean helps too; some owners use a non-stick mower deck spray on traditional mowers.
How to Choose the Right Worx Robotic Lawn Mower
Measure your lawn first. Mowers are rated by maximum area: WO7144 and WR310 for 1/4 acre, WR320 and WR342 for 1/2 acre, WR340 for 1 acre. Pick the model rated at or above your lawn size, not the grass area plus the house and driveway.
Look at slopes. If you have steep banks or bumpy ground, the WR342’s four-wheel drive and 84% slope rating is the clear pick. The others are best on gentler ground.
Think about security and edges. Only the WR340 and WR342 list Find My Landroid GPS tracking and the Cut-to-Zero blade. If your mower will be visible from the street, tracking and remote lock add peace of mind.
Check connectivity. RadioLink is listed on the WO7144 and WR320. If your Wi-Fi does not reach the far side of the yard, that is worth weighing. Shoppers comparing other robotic lawn mowers should look for the same wire-free and connectivity features.
