The WORX WG745 is a 40V cordless lawn mower designed for homeowners with small to midsize yards up to 1/4 acre. It combines the convenience of battery power with the performance of a brushless motor, making it a compelling alternative to gas mowers for those who value low maintenance and quiet operation.
Standout features include the brushless motor 2.0, which offers 40% higher cutting power and longer life than previous generations. IntelliCut technology automatically adjusts cutting speed based on grass density, optimizing runtime and ensuring a clean cut even in thick patches. The 2-in-1 system lets you mulch clippings for fertilizer or bag them for a tidy lawn.
Design and build quality are impressive for the price. At only 40 pounds, it is one of the lightest mowers in its class, and the cut-to-edge deck allows you to mow right up to borders. The collapsible handles and vertical storage option are great space savers in small sheds or garages. The single lever height adjustment offers six positions from 1 to 3 inches.
Potential drawbacks include a 17-inch cutting width, which is narrower than many 20-21 inch models, meaning more passes on larger lawns. It is not self-propelled, so you will need to push it yourself. While the included batteries cover 1/4 acre, larger yards may require purchasing an extra battery pack for uninterrupted mowing.
Overall, the WORX WG745 is an excellent choice for homeowners seeking a lightweight, efficient, and easy-to-store cordless mower. It delivers strong performance for small lawns, and the brushless motor ensures years of reliable service. If your yard is under 1/4 acre and you want to ditch gas and cords, this mower is a smart investment.
Pros

- Vision AI obstacle avoidance and cut-to-edge brushes reduce manual trimming
- Unlimited mowing zones, no-go areas, and four precision patterns via app
- V-SLAM sensor fusion keeps navigation reliable in shaded or partially covered areas
- RadioLink extends control beyond standard Wi-Fi range for larger lawns
Cons
- Designed for up to 1/4 acre lawns, so it is not suitable for larger yards.
- Full feature set depends on the app and a stable network connection during setup and operation.
- As a newer release, long-term field performance is not yet widely documented.
The WORX Wire-Free Robot Lawn Mower is designed for homeowners with up to 1/4 acre of grass who want precise, hands-off mowing without the hassle of laying boundary wire. It replaces perimeter cables with RTK Cloud positioning and Vision AI, so the robot learns your lawn, plans efficient routes, and returns to its charging station on its own.
In real-world use, the standout combination of centimeter-level RTK accuracy and V-SLAM sensor fusion keeps navigation stable in both open yards and shaded areas. Vision AI also recognizes common obstacles and border types, helping the mower avoid toys, flower beds, and other objects while cutting closer to edges using wheel brushes and cut-to-edge logic.
The app adds a high level of control: you can create unlimited mowing zones, set no-go areas, customize paths, and choose from Parallel, Checkerboard, Diamond, or Natural patterns. RadioLink connectivity extends communication beyond typical Wi-Fi range, which is useful for larger properties and hard-to-reach corners of the yard.
Build quality appears solid, with a two-wheel driver, durable brushes, spare blades, and a charging station included. The main drawbacks are the 1/4 acre size limit and the need for a smartphone for full setup and control. Since this is a new release, long-term reliability data is still limited, so it is best suited for early adopters who value advanced navigation and convenience.
Overall, the WORX robot mower offers a wire-free, app-driven mowing experience that is hard to match at this level of technology. For homeowners with a smaller lawn who want clean stripes, obstacle avoidance, and minimal setup, it is a compelling choice.

Buying Guide: What to Look for in a WORX 4WD Mower for Rough Terrain
Traction and Slope Handling
The most critical factor for rough terrain is how well the mower maintains grip. WORX 4WD robotic models like the WORX Robot Lawn Mower 4WD for 1/2 Acre feature a terrain-adaptive chassis that keeps all four wheels planted on uneven ground and raised borders. They can handle slopes up to 84 percent (about 40 degrees) without slipping. For walk-behind options, the self-propelled models with variable speed give you control on inclines. If your yard has steep or irregular slopes, prioritize 4WD and high slope ratings.

Navigation and Mapping
Rough terrain often includes obstacles like trees, rocks, and flower beds. WORX Vision Cloud robots use centimeter-level RTK Cloud accuracy combined with Vision AI to automatically map your yard and avoid obstacles. The AI processes up to 10 trillion operations per second to recognize and understand objects. Even in shaded areas, V-SLAM sensor fusion maintains precise navigation. This means your mower will not get lost or stuck on tricky ground. For wire-free operation, these models require no perimeter wire, making installation a breeze on uneven lots.

Cutting Performance and Edge Control
Rough terrain demands a mower that cuts cleanly without scalping or missing patches. WORX mowers feature Cut-to-Edge border cutting technology that trims close to fixed borders and crosses ridable edges. The 4WD models include a Cut-to-Zero offset blade that reduces the need for manual string trimming. For walk-behind mowers, Aerodeck technology prevents clogs and clumping, delivering a consistent cut even on bumpy ground. Choose a model with adjustable cutting heights (typically 1.5 to 4 inches) to adapt to uneven grass lengths.
