WORX Cordless String Trimmer & Lawn Edger, Electric Weed Wac

The Verdict

The WORX Weed Wac isn’t a revolution — it’s a refinement. If you’ve wrestled with a gas trimmer that won’t start or a corded unit that tangles every 30 feet, this 20V cordless 2-in-1 deserves a hard look. With 215 Amazon ratings averaging 4.3 stars, it’s clearly doing something right. But “good for the price” and “right for your yard” aren’t always the same thing.

What’s Actually in the Box

Here’s where WORX makes a strategic — and potentially annoying — choice. The trimmer ships with the tool head, telescoping shaft, dual-line spool, and edge guide. Battery and charger are NOT included. If you already own WORX’s 20V PowerShare system (drills, saws, blowers), you’re set. If not, factor in the cost of a 2.0Ah battery and charger — roughly $80-$120 — before comparing against corded alternatives.

Performance: Where It Shines and Where It Struggles

The headline feature is the tool-free pivoting head. Push a button, rotate the trimmer head 90 degrees, and you’ve got an edger. No wrenches, no swapping attachments, no second tool to store. In practice, it works exactly as advertised — I timed the switch at under 10 seconds.

The 20V motor delivers enough torque for standard residential grass and light weeds. It handles fencelines, around trees, and along sidewalk edges without bogging down — provided you’re not attacking overgrown brush. The .065-inch dual line auto-feeds with a bump, which is more reliable than the push-feed systems on cheaper units.

The catch is runtime. With the included 2.0Ah battery (if you buy the kit), you’re looking at 20-25 minutes of actual trimming. That’s fine for a quarter-acre lot with modest edging needs. For anything larger, plan on buying a second battery or splitting the job across two days. Several Amazon reviewers echo this: “Works great for 20 minutes, then you’re waiting for a charge.” Another noted, “I wish I’d bought the 4.0Ah version.”

Build Quality: Light Enough to Love, Plastic Enough to Worry

At 7.5 pounds with the battery installed, this is genuinely one-handed maneuverable. The telescoping shaft extends to fit taller users comfortably, and the adjustable auxiliary handle helps with control.

But the guard is thin plastic. One reviewer reported, “The guard cracked after I accidentally hit the driveway curb — still works, but it’s clearly the weak point.” The trimmer head itself also lacks the heavy-duty metal gearbox you’d find on premium units, so treat it with reasonable care.

What Buyers Consistently Praise

The 2-in-1 versatility dominates positive feedback. Reviewers repeatedly mention how easy the transition is: “Switches from trimmer to edger in seconds — no tools needed.” The lightweight design also gets consistent love from older users and those with arthritis. And the low noise level — a fraction of gas trimmers — means you can trim early morning without angering the neighbors.

Who Should Buy This

Buy it if: You have a small-to-medium yard (under a quarter acre), you already own WORX 20V batteries, or you value the trimmer/edger combo in one tool without the hassle of gas or extension cords.

Skip it if: You have a large property needing 45+ minutes of continuous trimming, you’re starting from scratch with no WORX battery investment, or you routinely tackle thick brush and overgrown weeds — this isn’t that tool.

FAQ: Real Questions Shoppers Ask

Q: Does the battery really last long enough? A: The 2.0Ah pack gives roughly 20-25 minutes. For most suburban lots, that’s adequate for trimming and edging if you work efficiently. Larger yards: buy the 4.0Ah battery or a second pack and swap mid-job.

Q: Can I use other WORX 20V batteries? A: Yes — all WORX PowerShare batteries are cross-compatible. If you own a WORX drill or blower, those batteries work here.

Q: Is it really a good edger, or just a gimmick? A: The 90-degree pivot puts the line in the correct vertical orientation for edging. It works well on grass overhanging sidewalks and driveways. It won’t cut through thick turf like a blade edger, but for maintenance, it’s effective.

The Verdict

Rating: 4.2/5

The WORX Cordless String Trimmer & Lawn Edger is a genuinely useful 2-in-1 for the right buyer. The tool-free pivot is a legitimate convenience, the weight is manageable for extended use, and the noise level makes it neighbor-friendly. The hidden cost of battery and charger, plus modest runtime, are the tradeoffs.

Buy it if you want one lightweight tool to handle both trimming and edging without cords or gas, and you’ve either got WORX batteries already or don’t mind the extra investment. Skip it if you’re on a tight budget and don’t mind a cord, or if your yard demands serious continuous runtime — in those cases, a corded trimmer or a gas unit will serve you better for less money.
