WORX String Trimmer Honest Review: What 27,000 Buyers Know Before You Do

I will tell you the thing nobody bothered to mention to me before I ordered the WORX 20V cordless string trimmer: the battery is not included. Not in all configurations, anyway. I found this out when I opened the box on a Saturday morning, ready to tackle the weeds climbing my fence line, and found a very nice trimmer with nowhere to plug in a power source. I stood there in my driveway holding a power tool the way you hold a phone you forgot to charge.

That is not a dealbreaker. But it is a detail the reviews often skip over, and it is the kind of thing that turns a good Saturday into a trip to the hardware store. I am going to give you the version of this review that I wish I had read: the specific things the listing photo and the star count do not communicate, alongside the genuine strengths that have kept this trimmer in my garage for two years now instead of at a garage sale.

The Battery Thing (Read This First)

The WORX 20V trimmer is sold in two configurations: tool-only and a bundle that includes a 2.0Ah battery and charger. The tool-only version is cheaper. The bundle costs more but actually comes with everything you need to turn the thing on. The Amazon listing I landed on defaulted to the tool-only configuration, and I missed it entirely. If you own other WORX 20V tools, you may already have a compatible battery, in which case tool-only is a great deal. If you are starting fresh, do not buy tool-only unless you have accounted for the battery cost separately.

WORX uses its own 20V MAX battery platform, branded PowerShare. The good news is that this battery works across most of their 20V lineup, so if you pick up the trimmer bundle and then later grab their 20V blower or hedge trimmer, that battery is already compatible. The ecosystem logic is real and actually useful, not just marketing language. But on day one, with weeds staring you down, the practical detail is: confirm which configuration you are buying before you click Add to Cart.

First Startup: What to Expect Out of the Box

Assembly is genuinely easy once you have the battery sorted. The shaft clicks into place, the guard snaps on, and the auxiliary handle slides onto the shaft and tightens with a twist knob. I had the whole thing together in under ten minutes without reading the instructions past the safety page. The spool comes pre-loaded with dual-strand line, so you do not have to wind anything before your first session. You just charge the battery, snap it in, and go.

One thing to do before your first cut: check that the line has enough exposed length. Sometimes the line retracts a bit during shipping and you end up with very short stubs that the trimmer head cannot grab properly. If the trimmer starts but cuts weakly or unevenly right out of the box, press the Command Feed button once or twice to advance a small amount of fresh line. That usually fixes it. It is not a defect, just a shipping quirk that catches people off guard and generates a handful of the one-star reviews that say 'does not work at all.'

How I Actually Use It (And What the Listing Photo Gets Wrong)

The product photo on Amazon shows the WORX trimmer in a wide, clean yard with a crisp edge running along a paved walkway. That image is doing a lot of work. My yard is a quarter-acre in northwest Georgia with a fence line that backs up to a scrubby tree line, two flower beds with brick edging, a strip of grass between the driveway and the street, and a corner patch that gets weedy regardless of what I do to it. I trim about twice a month in summer and less in fall. The WORX handles all of that without complaint.

What the listing photo implies, but does not explicitly say, is that the 12-inch cutting swath is on the narrower end of the category. Most corded and gas trimmers run 14 to 15 inches. If you have open, flat areas to cover and you are coming from a wider deck, you will notice the difference in pass count. For beds, fences, and borders, where you are doing precision work anyway, the 12 inches is actually an asset because it gives you more control. I have come to think of it as a precision trimmer that also handles open-area work, rather than the other way around.

The Edger Mode: Better Than I Expected, With One Catch

The edger conversion on the WORX is the feature I underestimated most. You press a button, rotate the head 90 degrees, and the trimmer becomes an in-line edger with a wheel guide that rides along the pavement surface. I was skeptical this would work cleanly because I had tried a similar pivot conversion on a cheaper trimmer and it flopped all over the place. The WORX version is genuinely stable. The wheel keeps the cutting line at a consistent depth, and the results along my driveway edge are noticeably cleaner than anything I got from the previous trimmer I owned.

The catch: edger mode chews through line faster than trimmer mode. The cutting action is more aggressive when the head is vertical and spinning against hard pavement. If your property has a lot of linear footage to edge, budget for more replacement spools. WORX sells them as a two-pack and they are not expensive, but they are not interchangeable with generic spools from the hardware store. You need WORX brand, specifically the ones sized for this model. Keep two packs on hand at the start of the season and you will not run out mid-job.

The edger conversion is the feature I underestimated most. I was skeptical a pivot-head would work cleanly. Two seasons later, my driveway edge looks like someone took a straightedge to it.

Command Feed: The Line Feed System They Actually Got Right

String trimmer line feed mechanisms have a long and undistinguished history of being terrible. Bump-feed systems bump unevenly, auto-feed systems feed too much line and waste the spool, and manual feed systems require you to stop, fiddle, and occasionally throw the thing into the bushes in frustration. The WORX Command Feed works differently: you press a button on the head to advance line on demand. No bumping. No automatic dump. You decide when more line is needed, which turns out to be a much better mental model for how trimming actually works.

After two seasons, my main feedback on the Command Feed is that it is better than advertised but not completely flawless. Occasionally, usually when I have let the line get too short before advancing, the advance button does nothing and I have to stop and manually pull the line out a small amount to reset. This happens maybe once every three or four sessions. It is a minor annoyance rather than a design flaw. The fix is simple: advance line before it gets critically short rather than waiting until the head is almost bare.

Battery Life in Real Use

The 2.0Ah battery that comes with the bundle has a realistic runtime of 25 to 35 minutes under normal trimming conditions. That sounds modest until you time how long your actual trimming session takes. I did this. My full quarter-acre perimeter, fence line, around both beds, and the driveway edge takes me about 22 minutes. I finish with battery left over. If your property is larger, or if you have dense, thick grass that pushes the motor harder, you may find one charge is not quite enough for a complete circuit.

The upgrade path is a 4.0Ah PowerShare battery, sold separately. It is roughly twice the capacity and runs noticeably longer, though it also adds weight to the tool. My recommendation: start with the 2.0Ah that comes in the bundle, time your actual trimming session once, and decide from there. A lot of people buy the larger battery preemptively and never actually need it. The 2.0Ah covers most standard suburban yards without drama.

Charging takes about 50 to 60 minutes for a full charge from empty with the included charger. I keep the battery on the charger the night before mowing day. That is the whole routine. There is no priming, no choke, no fuel to mix, no cord to manage. For someone who dealt with a gas trimmer for years before this, the simplicity of that sequence is genuinely difficult to overstate. You just pick it up and it works.

The Weight and Handle: Lighter Than It Looks, Adjustable in the Right Ways

The WORX 20V weighs about 5.3 pounds with the battery in. That is light. My old gas trimmer was close to nine pounds and I would feel it in my shoulder by the time I finished the back yard. At 5.3 pounds the WORX does not tire you out the same way, which matters more than you might expect if you have ever had to stop mid-yard because your arm was done.

The shaft adjusts for height. I am five-foot-four and I run mine at a shorter setting than the factory default. My neighbor borrowed it, he is six-one, and he adjusted it in about ten seconds without reading the manual. The auxiliary front handle is also adjustable and makes edging more comfortable because you can position it to support a slightly different arm angle when the head is rotated vertical. Neither of these things sounds exciting, but both of them reduce fatigue across a 20 or 30 minute session, and that matters when you are doing this every other week all summer in July heat.

Who This Is For

The WORX 20V is the right trimmer if you have a standard suburban yard between about 2,000 and 8,000 square feet of perimeter, beds, and fence line. It is especially well matched for yards where edging is a meaningful part of your routine, because the pivot-to-edger feature does that job better than a separate edger tool at twice the price. It also makes sense if you are beginning to build out the WORX 20V PowerShare ecosystem, since the battery transfers to their blowers, hedge trimmers, and other 20V tools. If you want one lightweight cordless trimmer that handles both trimming and edging cleanly without buying two pieces of equipment, this is the one to look at.

It is also a solid pick for gardeners who are coming from gas and are exhausted by the fuel-mixing, choke-fiddling, pull-cord reality of that experience. The WORX will not be the most powerful tool you have ever held. But it will start, every single time, with one button press. After a few seasons of that, the power trade-off starts to feel like a very good deal.

Who Should Skip It

If you have more than a half-acre of open trimming area, this trimmer will feel slow compared to a wider deck or a higher-powered gas machine. The 12-inch swath just cannot move ground fast enough at larger scale without doubling your session time. If you regularly deal with thick, woody overgrowth or weeds that have grown a thick stem over the winter, the 20V motor will bog. You need more voltage or more torque for that kind of reclamation work.

Also worth saying: if you are buying a trimmer for a vacation property or a situation where it might sit unused for several months at a stretch, the battery will self-discharge over that time and may need reconditioning before it holds a full charge again. A corded electric trimmer is a more reliable option for occasional or seasonal use when storage conditions are not ideal. For a primary residence with a regular lawn maintenance schedule, though, the WORX earns its place on the hook.
