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.

Buying Guide: What to Look for in an Automatic Mower for 1 Acre
Coverage Area and Battery Runtime
A 1-acre lawn is roughly 43,560 square feet. The mower you choose must either have a large enough battery to finish the job in one pass or support auto-recharge and resume. Robot mowers like the WORX Robot Lawn Mower for 1 Acre are designed specifically for this size, while others like the Mammotion LUBA 2 AWD 5000HX can handle up to 1.48 acres. Cordless walk-behinds, such as the Worx Cordless Lawn Mower 40V 21-inch models, typically cover up to 1/2 acre per charge, so you may need two batteries or a quick swap.
For larger lawns, robots with auto-return and recharge are a game changer. They mow in segments, go back to charge, and then resume exactly where they left off. This feature is essential for uninterrupted coverage. If you have a complex property with multiple zones, consider reading our guide on mowing large complex properties effortlessly.
Navigation Technology: RTK, Vision, and LiDAR
Wire-free mowers rely on advanced positioning systems instead of perimeter wires. RTK (Real-Time Kinematic) provides centimeter-level accuracy using satellite signals and a reference station. Vision AI adds camera-based object recognition to avoid obstacles and map your lawn automatically. Some models, like the WORX Robot Lawn Mower for 1/4 Acre and the ANTHBOT M9, combine RTK with dual cameras for reliable navigation even under trees. For shaded yards, look for V-SLAM sensor fusion, which maintains precision when satellite signals weaken. Learn more about top RTK LiDAR vision robot mowers for wire-free precision.
Slope Handling and Terrain Adaptability
If your acre includes hills, dips, or uneven ground, you need a mower with strong climbing ability and all-wheel drive. The Mammotion LUBA 2 AWD 5000HX boasts an 80% slope rating (38 degrees) with four-wheel motors that power through thick grass and steep inclines. The RoboUP Raccoon 2 SE handles moderate slopes but is better suited for flatter lawns. For rough terrain, consider our picks for hybrid navigation mowers for rough terrain.
Smart Features and App Control
Modern automatic mowers come with app-based controls for scheduling, zone management, and real-time tracking. Look for models that let you create no-go zones, set mowing patterns (parallel, checkerboard, diamond), and receive notifications. The WORX Robot Lawn Mower for 1 Acre offers infinite zone mowing and remote control via the app, while the ANTHBOT N8 includes a 4-in-1 system that can sweep leaves and mulch. For yards with heavy tree cover, see our top mowers for large yards under trees.
Final Thoughts
After evaluating all nine models, our top recommendation for a fully automated, wire-free experience on a 1-acre lawn is the WORX Robot Lawn Mower for 1 Acre, thanks to its centimeter-level RTK Cloud accuracy, AI obstacle avoidance, and cut-to-edge border trimming. If your property features steep slopes or rough terrain, the Mammotion LUBA 2 AWD 5000HX Robot Lawn Mower offers unbeatable off-road capability with all-wheel drive and 4G connectivity. Both models deliver the hands-free convenience you need to reclaim your weekends.
