- Automatic line feed reduces downtime and keeps you working without interruption.
- Adjustable handle and head allow a custom fit for comfortable use in various positions.
- Lightweight and easy to handle, even for extended periods.
- Battery compatibility with a wide range of Worx tools adds long-term value.

The Worx WG170.9 is a 3-in-1 cordless tool that combines a string trimmer, lawn edger, and mini mower into one lightweight package. It is designed for homeowners with small to medium yards who want to simplify their lawn care routine without investing in multiple machines.
Standout features include Command Feed technology, which lets you advance trimmer line at the push of a button, eliminating the need to stop and manually bump the head. The adjustable handle offers seven positions, and the rotating head has six settings, making it easy to reach under bushes, along fences, and around flower beds. The 12-inch cutting width and 7600 RPM motor provide ample power for most residential trimming and edging tasks.
Build quality is solid for a cordless tool in this price range. The materials feel durable, and the quick-change mechanism between trimmer, edger, and mower is intuitive. At 4.6 pounds, the tool is light enough for one-handed use when trimming, and the included edger wheels add stability for straight-line edging. The battery is shared with Worx's Power Share family, so if you already own Worx 20V tools, you can use the same battery.
One drawback is that the battery and charger are sold separately, which increases the initial investment for new buyers. Also, the mini mower function works best on small, level patches of grass and is not a substitute for a full-size mower. Additionally, the fixed-speed trigger may not suit those who prefer variable speed for delicate trimming near plants.
Overall, the Worx WG170.9 offers excellent versatility and convenience for its price. It is a smart choice for anyone looking to consolidate their lawn tools and reduce clutter, as long as they are comfortable with the battery not being included and have realistic expectations for the mini mower function.

- Powerful turbine blower moves heavy wet leaves and debris with ease.
- Lightweight design reduces fatigue during long yard sessions.
- On-demand line feed eliminates messy bump-feed systems.
- Excellent value bundle with two batteries and quick charger.

The WORX WG928 is a cordless lawn care kit that combines a 12-inch string trimmer/edger with a 360 CFM turbine leaf blower. This bundle is designed for homeowners who want the convenience of battery power without sacrificing performance. With two 20V batteries and a rapid charger included, it delivers enough runtime for typical suburban yards.
Standout features include the trimmer's ability to pivot into an edger with a simple head rotation, effectively giving you three tools in one. The command feed system lets you advance trimmer line at the push of a button, keeping the cutting edge sharp. The leaf blower uses turbine technology inspired by jet engines to produce a wide, powerful air stream that easily clears leaves, grass clippings, and driveway debris.
Both tools are impressively lightweight, with the blower weighing only 4.4 pounds and the trimmer 5.3 pounds with battery attached. This makes them easy to maneuver for users of all strength levels. The build quality feels solid for the price point, and the black and orange color scheme is both functional and attractive.
Potential drawbacks include a modest battery runtime that may require a recharge for larger lawns, and the blower lacks variable speed control, limiting fine-tuning for delicate cleanup. The line feed mechanism can occasionally jam if used in extremely thick vegetation. However, these issues are minor for the intended home use.
Overall, the WORX WG928 kit offers outstanding value for homeowners seeking an all-in-one cordless solution. The combination of a versatile 2-in-1 trimmer/edger, a powerful leaf blower, and included batteries makes yard work faster and more enjoyable. It earns a strong recommendation for its performance, convenience, and price.
Pros
- Powerful brushless motor with extended runtime for thick weeds
- Three tools in one saves money and storage space
- Easy push-button line feed eliminates bumping
- Ergonomic adjustable handle and telescopic shaft reduce fatigue
- Wheeled edging guide ensures clean, straight edges
Cons
- 20V system may lack power for very large or dense lawns compared to 40V/80V models

The WORX WG173 is a 20V cordless 3-in-1 trimmer, edger, and mini mower designed for homeowners who want a lightweight, battery-powered solution without sacrificing performance. It's ideal for small to medium yards, especially those with varied terrain and tight spaces around gardens, sidewalks, and flower beds.
Its standout feature is the brushless motor paired with a 4.0Ah battery, which delivers gas-like torque through thick weeds while offering 30% more runtime and 2x the cutting efficiency of brushed motors. The 13-inch dual-line head covers more ground quickly, and the electronic push-button line feed lets you advance string instantly without stopping or bumping — a real time-saver.
The 3-in-1 versatility is backed by a 90° pivoting head that adapts to slopes and uneven ground, plus dual support wheels for precise edging along driveways and patios. The integrated flower guard protects your plants, and the adjustable handle and telescopic shaft ensure a comfortable fit for users of different heights. When done, the tool collapses for compact storage.
Potential drawbacks: the 20V system may not have the sustained power for very large or overgrown lawns compared to higher-voltage models, and there are currently no user reviews to gauge long-term durability. Also, while the included battery is good for typical use, larger yards may require a spare battery.
Overall, the WORX WG173 offers excellent value as a versatile, easy-to-use cordless trimmer that simplifies yard maintenance. If you value convenience, adjustable ergonomics, and the ability to trim, edge, and mini-mow with one tool, this is a strong choice — just consider your yard size and power needs.
Pros
- Patented DNA line reduces drag and improves cut quality
- Flexible material absorbs impact on hard surfaces for durability
- Higher tensile strength (100 lbs) than standard lines
- Easy snap-in installation compatible with WORX trimmers
- Two spools per pack offer good value for frequent users
Cons
- Only compatible with WORX string trimmers, not universal
- 10 feet per spool may require frequent changes for large yards
- Orange color may fade or be less visible in tall grass
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.
Buying Guide
Versatility: 2-in-1 vs. 3-in-1
One of the biggest decisions you’ll make is between a 2-in-1 and a 3-in-1 model. The 2-in-1 tools, like the WORX 20V 12″ 2-in-1 Cordless String Trimmer, pivot from trimming to edging with a simple twist. This is perfect for basic lawn maintenance.
The 3-in-1 models add a mini-mower function, which is great for tight spots under decks or around garden beds where a full-size mower can’t reach. If you have many nooks and crannies, the extra versatility is worth it. For larger yards, you might also consider a robot mower; see our best WORX robot lawn mower for large yards for automated options.
Battery and Power
All Worx 20V trimmers use the Power Share battery platform, meaning one battery works across a wide range of tools. When choosing a model, consider what’s included in the box. Some come with one battery, others with two, and a few include a charger. If you have a larger yard, a model with a 4.0Ah battery, like the WORX 20V 13″ 3-in-1 Cordless String Trimmer/Lawn, will give you more runtime.
Brushless motors are another plus, offering more power and efficiency. The WG173’s brushless motor delivers gas-like performance, making it a top choice for thick weeds. For hilly terrains, you might want to explore all-terrain mowers; our best All-Terrain mowers for hilly lawns guide can help.
Line Feed and Cutting Diameter
Nothing kills momentum like stopping to bump the trimmer head for more line. Worx’s Command Feed technology lets you push a button to advance the line instantly, a feature on most models. The cutting diameter (usually 12 inches) determines how wide a swath you can clear. A larger diameter means fewer passes, but also requires a bit more power.
Comfort and Adjustability
Since trimming and edging can take a while, ergonomics matter. Look for adjustable handles, telescoping shafts, and pivoting heads. These features let you customize the tool to your height and reach awkward spots without straining. The 7-position handle and 90° tilting head on several Worx models are excellent for this.
Final Thoughts
Choosing the right Worx 20V cordless trimmer and edger comes down to your yard’s specific needs. For most homeowners, the Worx 20V 12″ 3-in-1 Cordless String Trimmer/Lawn offers an unbeatable blend of versatility and value, handling trimming, edging, and mini-mowing with ease. If you need extra power for dense vegetation, the WORX 20V 13″ 3-in-1 Cordless String Trimmer/Lawn with its brushless motor is the superior choice, promising faster, more efficient cutting.

Frequently Asked Questions
How long does the battery last on a Worx 20V trimmer?
Battery life varies by model and usage. With a standard 2.0Ah battery, you can typically expect 20-30 minutes of continuous trimming. Models with a 4.0Ah battery, like the WG173, offer roughly double that runtime. Always check the included battery capacity when purchasing.
Can I use the same battery for other Worx tools?
Yes, all Worx 20V trimmers use the Power Share battery system. This means the included battery and charger work with over 75 other Worx 20V, 40V, and 80V tools, including leaf blowers, chainsaws, and hedge trimmers. It’s a cost-effective way to expand your tool collection.
How do I change the trimmer line on a Worx trimmer?
Worx trimmers feature a Command Feed spool system. To replace the line, you simply open the spool holder, remove the old spool, and insert a new one. The push-button feed mechanism automatically advances the line when you need it, so you don’t have to bump the head.
Are Worx cordless trimmers powerful enough for thick weeds?
Standard Worx 20V trimmers handle normal grass and light weeds well. For thick, overgrown vegetation, we recommend the brushless model (WG173) with a 4.0Ah battery. Its high-torque motor maintains speed under load, cutting through dense growth more effectively.
