Detailed Review

The WORX WG745 is a 40V cordless lawn mower designed for homeowners with small to midsize yards up to 1/4 acre.

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.

  • As a newer release, long-term field performance is not yet widely documented.
Detailed Review

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.

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.

  • Single-lever height adjustment is quick and tool-free.
  • Battery system shares power with other Worx tools.

Cons

  • 20V battery may not provide enough runtime for larger lawns without spare batteries.
  • 14-inch cutting deck is narrow, requiring more passes on medium-sized lawns.
  • No self-propelled feature; manual push only.
Detailed Review

The Worx WG733.1 is a 20V cordless lawn mower designed for homeowners with small to medium-sized yards who value precision and ease of use. Its 14-inch cutting deck and compact form factor make it ideal for navigating tight spaces, flower beds, and garden borders where larger mowers struggle.

One standout feature is the cut-to-edge design, which allows the mower to trim grass right up to fences and edging without leaving a strip behind. This reduces the need for a separate string trimmer, saving time and effort. The 2-in-1 capability lets you choose between bagging clippings for a clean look or mulching to return nutrients to the soil.

The brushless motor is a key upgrade over brushed alternatives, providing longer runtime and better efficiency. The 6-position single-lever height adjustment (1 to 3 inches) lets you quickly adapt to different grass conditions. At 21.7 pounds, the mower is lightweight and easy to push, though it is not self-propelled.

Potential drawbacks include the 20V battery's runtime, which may be insufficient for larger lawns without an additional battery. The 14-inch width also means more passes on medium-sized areas. However, for its target audience, these trade-offs are acceptable given the mower's precision and portability.

Overall, the Worx WG733.1 is a reliable choice for small-lot homeowners who want a cordless mower that can edge closely and store easily. It offers good value with its Power Share battery system and brushless motor, making it a smart addition to any lawn care routine.

  • As a new model with zero reviews, performance in real-world conditions is unverified.
Detailed Review

The Worx WG752 cordless lawn mower is designed for homeowners with lawns up to half an acre who want the convenience of battery power without sacrificing cutting performance. This 21-inch walk-behind mower features a brushless motor 2.0 and innovative Aerodeck technology to deliver efficient, clog-free cuts across various grass conditions.

Standout features include IntelliCut, which automatically adjusts motor speed in thick grass to maintain power, and the Aerodeck that increases airflow to prevent clumping. In practice, this means fewer passes and less time spent clearing debris from the deck. The included two 20V 5Ah PowerShare Pro batteries provide solid runtime, and the 4A dual charger gets you back to work quickly.

Build quality is robust with a 55.6-pound weight that feels stable but may be heavy for some users. The collapsible handle and vertical storage design are thoughtful for compact spaces. Height adjustment via a single lever (1.5 to 4 inches) is straightforward, and switching between mulching, bagging, and side-discharge is tool-free.

Potential drawbacks include the lack of self-propulsion, which can make mowing slopes tiring, and the reliance on two 20V batteries rather than a single higher-voltage pack. Additionally, as a newly released model with no customer reviews yet, long-term reliability is unclear.

Overall, the Worx WG752 offers a compelling package of power, efficiency, and versatility for cordless mower buyers. If you value innovative features like Aerodeck and IntelliCut and already own WORX PowerShare tools, this mower is a strong choice for medium-sized lawns.

Buying Guide for Slope Mowers

Choosing the right mower for slopes involves more than just wheel size. Here are the key factors we evaluated in selecting the best WORX 4WD mower for slopes.

Slope Rating and Traction

WORX rates its 4WD robotic models for slopes up to 84% (40°). That means they can climb a hill that rises 84 cm every 100 cm horizontally. The terrain-adaptive chassis keeps all four wheels planted on uneven ground, while true front-wheel steering prevents turf tearing during turns. For steeper lawns, choose a dedicated 4WD robot; for moderate hills, a self-propelled cordless mower with good tire grip may suffice.

If your yard combines slopes with bumps, read our best WORX mower for uneven terrain guide.

WORX Vision Cloud mowers use RTK cloud positioning for centimeter-level accuracy, even in open areas. When your slope has trees or shade, V-SLAM sensor fusion with Vision AI takes over. The neural network processes up to 10 trillion operations per second to recognize objects like flower beds, rocks, and garden furniture. This ensures the mower navigates safely without getting stuck or damaging your landscape.

Automation and Zoning

All WORX 4WD robots support infinite zone mowing. You can create custom pathways, set no-go areas, and edit the map via the app. This is especially useful on slopes where you may want to avoid particularly steep sections or keep the mower away from flower beds. The auto-mapping feature uses Vision AI to understand your lawn shape and boundary types from day one, saving you setup time.

Cut Quality and Edge Trimming

WORX robotic mowers offer Cut-to-Edge technology that crosses ridable borders to reduce leftover grass, and Cut-to-Zero offset blades trim closer along fixed boundaries. On slopes, this means fewer passes with a string trimmer. The precision mowing patterns (parallel, checkerboard, diamond) are RTK-accurate, giving your slope a professionally striped look.

Final Thoughts

For homeowners with sloped lawns, the best WORX 4WD mower for slopes comes down to yard size and desired automation level. If you manage half an acre or more, the WORX Robot Lawn Mower 4WD for 1/2 Acre delivers exceptional traction, RTK navigation, and AI obstacle avoidance. For larger properties up to one acre, the WORX Robot Lawn Mower 4WD for 1 Acre offers the same features with extra battery capacity and coverage. Both models eliminate perimeter wires and let you control zones from your phone, turning steep terrain into a hands-free mowing experience.

Frequently Asked Questions

Can a WORX 4WD mower handle slopes steeper than 40 degrees?

WORX 4WD robotic mowers are rated for slopes up to 84% (about 40°). For steeper gradients, consider a different machine or manual mowing. The terrain-adaptive chassis and four-wheel drive provide excellent grip up to that limit.

Do I need to install a perimeter wire for WORX slope mowers?

No. The Vision Cloud models (WR341, WR342, WR344) use RTK cloud accuracy and Vision AI to map your lawn without a boundary wire. This makes setup simpler and avoids tripping hazards on hills.

Will the mower get stuck in thick grass on a slope?

The WORX 4WD robots are equipped with a brushless motor and intelligent power management. The terrain-adaptive chassis also helps maintain traction. For extremely dense grass, the mower may adjust cutting height or speed automatically.

How does the app handle multiple zones on a sloped yard?

The WORX app allows you to create unlimited mowing zones, set custom paths, and define no-go areas. You can also schedule different mowing days for different slopes. For more on app capabilities, see our All-Terrain Mowers section.
