Pros
- Lightweight and easy to push and maneuver, even on slopes
- Powerful brushless motor with long runtime and durability
- Cut-to-Edge design minimizes manual trimming
- Single lever height adjustment with 6 positions for different grass types
- Battery charge indicator keeps you informed of remaining power

- Batteries may not be sufficient for lawns larger than 1/4 acre without additional packs
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
- Wide compatibility with many Worx Landroid models
- Sharp double-sided blades for efficient cutting
- Easy screw-in installation with included hardware
- Excellent value with 24 blades in one pack
- Reliable customer service for quality issues
Cons
- Not original Worx parts, may differ slightly from OEM blades
- Large 24-pack may be excessive for small lawns with infrequent blade changes
- Compatibility list is extensive but not guaranteed for every model variation
The Cilivo WA0190 replacement blade kit is a practical and cost-effective solution for owners of Worx Landroid robotic mowers. Designed to fit a wide range of models including the WG794, this 24-pack provides enough blades for multiple seasons of lawn care. It is especially suited for those who prefer to keep a stock of spare parts on hand rather than ordering individual replacements.
Each blade features a double-sided sharp edge that cuts grass cleanly on both sides, extending the usable life of each blade. In real-world use, these blades perform well on various grass types and terrains, delivering a consistent cut that keeps lawns looking manicured. The included screws make swapping old blades for new ones quick and tool-friendly, minimizing downtime for the mower.
The build quality is solid for a replacement blade set. The metal is sturdy enough to handle regular mowing without bending or dulling prematurely. While they are not original Worx parts, they are manufactured to close tolerances that ensure a snug fit and reliable operation. The 24-blade count is a standout feature, offering significant savings compared to buying smaller packs or individual blades.
A potential drawback is that the kit may include more blades than needed for very small yards, and some users might prefer the assurance of OEM parts. Additionally, while compatibility is broad, it is always wise to double-check fitment for specific older or newer model variants. However, the responsive customer service team is available to address any fitment or quality issues quickly.
Overall, the Cilivo WA0190 replacement blade kit is a smart purchase for Worx Landroid owners who value convenience and economy. It delivers dependable performance, easy installation, and excellent value, making it a recommended accessory for maintaining a robotic mower's cutting efficiency throughout the year.

- Easy snap-in installation compatible with WORX trimmers

The WORX WA0004 Replacement Spool & Line is a 2-pack designed specifically for WORX string trimmers. Each spool contains 10 feet of the patented Double Helix DNA Line, an oval-shaped line that reduces air resistance and delivers cleaner cuts. This product is ideal for homeowners and DIYers who want a reliable, long-lasting trimmer line that handles tough weeds and edging against concrete.
Standout features include the aerodynamic design that cuts through air and grass with less drag, which puts less strain on the trimmer motor and extends tool life. The line is also flexible, stretching slightly on impact with hard surfaces like decks or sidewalks, reducing breakage and lasting longer than standard round lines. With a tensile strength of 100 pounds, it outperforms older lines rated for only 68 pounds, resisting snapping and fraying during heavy use.
In real-world performance, users report that the DNA Line provides a noticeably smoother trimming experience with fewer tangles and less vibration. The line feeds consistently from the spool, minimizing downtime. The orange color makes it easy to see the line while trimming, though some may find it less visible in tall grass. Overall, the line holds up well against thick weeds and edging, though very dense brush may still cause occasional breakage.
A potential drawback is compatibility: this spool is designed only for WORX trimmers, so owners of other brands cannot use it. Additionally, 10 feet per spool may not be enough for very large lawns, requiring more frequent spool changes. Some users also note that the line can be slightly more brittle in cold weather, though this is common with many trimmer lines.
Verdict: The WORX WA0004 Replacement Spool & Line is a top-tier choice for WORX trimmer owners who want a durable, efficient line that reduces motor strain and lasts longer against hard surfaces. The 2-pack offers good value, and the patented DNA design delivers real performance benefits. If you own a WORX trimmer, this is a reliable upgrade over standard lines.
Choosing the Right WR155 Accessories: Key Buying Criteria
When selecting products for your WORX WR155, focus on three main factors: blade quality, battery compatibility, and terrain handling. High-quality blades ensure a clean cut, while a robust battery system extends runtime. For slopes, a rear weight holder can prevent tipping. Always verify compatibility with the WR155 model to avoid fitment issues.
Blade Replacements: Keeping the Edge
Regular blade changes are crucial for a clean cut. The Cilivo WA0190 Replacement Robotic Lawn Mower blades are sharp, durable, and compatible with the WR155. For a budget-friendly option, the Kudoosen 24pack WG794 WA0190 Replacement Robotic blades offer excellent value without compromising quality.

For shrubbery, the WORX Cordless Grass Shear & Shrub Trimmer offers 2-in-1 functionality with interchangeable blades. It’s ideal for detailed trimming around flower beds and bushes.
