If your lawn mower sounds like a Boeing 737 on takeoff and weighs approximately as much as your regrets, it might be time to make a change. The Worx WG779 40V Cordless Lawn Mower promises something genuinely different: quiet, cordless, lightweight cutting that won’t wake up the neighborhood at 7 a.m. We’ve spent serious time with this mower — testing the IntelliCut technology, battery performance, and real-world cut quality — and we’re ready to give you the full story. Spoiler: your neighbors really won’t know you’ve been outside.
This Worx WG779 40V Cordless Lawn Mower review covers everything from unboxing and assembly to live mowing performance, so you can decide whether this compact 14-inch deck is the right fit for your yard in 2026.
Quick Verdict
⚡ Our Verdict: Highly Recommended for Small Yards
Rating: 4.3 / 5 ⭐⭐⭐⭐
The Worx WG779 is a genuinely impressive cordless mower for anyone managing up to 1/8 acre. It’s whisper-quiet at 87.8 dB, weighs under 30 lbs, and the dual-battery PowerShare system is a serious long-term value add. IntelliCut is the real deal — it adjusts torque automatically so you’re not burning through battery in light grass. The 14-inch deck is tight enough for narrow passages but means more passes on wider lawns. If you’re stepping away from a gas mower or an unwieldy corded model, the WG779 will feel like a revelation.
Best for: Small yards up to 1/8 acre, urban gardens, townhouse plots, and existing Worx PowerShare tool owners.
Skip if: You’re mowing more than 1/4 acre or need a wider deck for faster coverage.

Performance Review: Worx WG779 40V Cordless Lawn Mower in Action
Let’s talk about what actually matters: does the Worx WG779 40V Cordless Lawn Mower cut grass well? The short answer is yes — consistently and cleanly, provided you’re working within its intended use case. The two 20V 4.0Ah batteries combine for a genuine 40V output, and the dual-battery system means you can hot-swap mid-session if needed, though most users covering up to 1/8 acre report finishing without needing to.
IntelliCut Technology
This is the standout feature and it earns its billing. Worx’s patented IntelliCut sensor technology continuously reads grass density and adjusts blade speed accordingly. Push into a thick patch and the motor ramps up torque automatically. Cruise across a lighter section of lawn and it pulls back, conserving battery. In real-world testing, this felt intuitive and seamless — not a gimmick. Over a typical mowing session, IntelliCut genuinely extends your runtime compared to a fixed-speed motor running flat out the entire time.
Battery Life and Runtime
With both 4.0Ah batteries installed (via the dual-slot system), you’re looking at solid coverage of up to 1/8 acre. Heavier, longer grass will eat into that range, and it’s worth planning ahead if your lawn is on the larger side or you want to double-pass for a striped finish. The included dual charger means both batteries top up simultaneously, which reduces downtime significantly compared to single-charger setups.
Cut Quality and Height Adjustment
The single-lever 6-position height adjustment is one of the most user-friendly systems we’ve tested. Flip it, and the entire deck raises or lowers uniformly between 1.5 and 3.5 inches — no wrestling with individual wheel clips. The cut quality across all six settings was even and clean. Mulching performance was particularly impressive: clippings were finely shredded and distributed evenly, which is exactly what you want for lawn health. The 0.85-bushel bag does fill up faster in thick grass, but the full-bag indicator prevents the guesswork.
Noise Level
At 87.8 dB, the WG779 is significantly quieter than any gas-powered equivalent (typically 94–100 dB). It’s not silent — hearing protection is still a sensible call — but early morning mowing without waking the street is a realistic scenario. Multiple users have specifically cited this as a reason they won’t go back to gas. We’d agree: the noise reduction alone is a meaningful quality-of-life upgrade.
Design and Build Quality
The Worx WG779 is built around one clear design priority: usability. At under 30 lbs, it’s light enough to lift, carry, and push up moderate inclines without strain. The 14-inch compact deck threads through narrow garden gates, between landscaping features, and around tree bases without the usual wrestling match a full-size mower demands.
The handle folds completely flat for storage, making this one of the few mowers that can comfortably live in an apartment storage closet or a small shed without dominating the space. The carry handle on the deck is thoughtfully placed for one-handed transport. Build quality is generally solid — predominantly robust plastic construction, which keeps weight down and resists rust. Some users have reported minor factory assembly inconsistencies, so we’d recommend a thorough check of all fasteners before first use.
The PowerShare battery platform deserves a specific mention in any discussion of design value. The fact that these same 20V batteries can power over 140 Worx tools — from drills to trimmers to blowers — means you’re not just buying batteries for a mower. You’re investing in an ecosystem. One user noted they switched to Worx specifically because of this interoperability, and four months later, they’re still enthusiastic about the decision.
What Real Buyers Are Saying
“Love it for being lightweight, quiet, and easy to store. It handles my small front and back yard without breaking a sweat — or waking my neighbors.” — ⭐⭐⭐⭐⭐ Verified Buyer
“I already owned several Worx tools, so the battery compatibility sealed the deal. Four months in and it’s still one of my most-used tools in the garage. The IntelliCut feature is genuinely smart — not marketing fluff.” — ⭐⭐⭐⭐⭐ Verified Buyer
“Good to plan ahead if you have a bigger yard or want to go over it twice. But for my place? Two batteries is exactly what I need and I’ve never run out mid-mow.” — ⭐⭐⭐⭐ Verified Buyer
And then there’s this review that honestly just nails the experience:
“My neighbor knocked on the door mid-mow to ask if I was actually cutting grass or just walking around with something. That’s how quiet this thing is.” — ⭐⭐⭐⭐⭐ Verified Buyer
Honestly, fair enough.
Value for Money
Here’s where the Worx WG779 makes a genuinely compelling case. The box includes the mower, two 4.0Ah batteries, and a dual charger. Buying those batteries separately in the Worx ecosystem would cost a meaningful sum on their own, so the bundled value is real and not just marketing padding. For small-yard owners who are done with gas (oil changes, spark plugs, carburetor cleaning, pull-cord drama), the total cost of ownership comparison swings firmly in the WG779’s direction over time.
If you’re already in the Worx PowerShare ecosystem, the WG779 becomes even more attractive — you can redistribute those batteries across your entire tool fleet. And if you’re new to Worx, this is a smart entry point into a platform that covers drills, sanders, leaf blowers, hedge trimmers, and well beyond 140 tools. You can see the latest deals and bundle pricing on Amazon to confirm current value.
The one honest caveat: if your yard is pushing 1/4 acre or larger, this mower will feel like hard work — not because it cuts poorly, but because the 14-inch deck means significantly more passes. At that size, you’d want to look at a wider-deck 40V or 56V model. For its intended use case, though, the value-to-performance ratio here is strong.

Frequently Asked Questions
How long does the battery last on the Worx WG779?
With both included 4.0Ah batteries powering the 40V system, the WG779 can handle up to roughly 1/8 acre per full charge. Actual runtime depends on grass thickness, terrain, and how frequently IntelliCut needs to boost torque. For most small yards, a single charge session comfortably covers the entire lawn. If you have a larger yard or plan to double-pass, fully charging both batteries before you start is a smart habit.
Can I use the Worx WG779 batteries with other Worx tools?
Yes — and this is one of the WG779’s best features. The 20V 4.0Ah batteries are part of the Worx PowerShare platform, which means they’re compatible with over 140 Worx tools including drills, hedge trimmers, leaf blowers, and sanders. If you already own Worx PowerShare tools, your existing batteries will work in this mower, and vice versa.
Is the Worx WG779 good for hills?
For moderate inclines, yes. At under 30 lbs, the WG779 is significantly easier to push uphill than heavier gas or larger electric mowers. It won’t self-propel, but the lightweight design compensates well. Steep grades will be more challenging — in that case, a self-propelled model would be worth considering.
What is IntelliCut and does it actually work?
IntelliCut is Worx’s patented sensor technology that automatically adjusts the blade’s cutting speed based on grass density. When the mower detects thick or tall grass, it ramps up motor speed and torque. In lighter areas, it dials back to conserve battery. In our testing and across multiple user reports, IntelliCut performs as advertised — it’s a genuine power-saving feature, not just a marketing label.
Does the Worx WG779 mulch and bag?
Yes. The WG779 is a 2-in-1 mower. It ships with a mulch plug (which redirects clippings back onto the lawn as natural fertilizer) and an 0.85-bushel collection bag. Switching between modes is straightforward. The collection bag includes a full-bag indicator so you know when it’s time to empty without having to keep manually checking.
Conclusion
The Worx WG779 40V Cordless Lawn Mower is one of the most thoughtfully designed small-yard mowers on the market in 2026. It’s quiet enough for early morning sessions, light enough to push without fatigue, smart enough to manage its own battery usage through IntelliCut, and practical enough to fold flat and live in a closet. The dual-battery bundle with a PowerShare-compatible ecosystem seals the deal for anyone who wants long-term tool flexibility beyond just lawn care.
It’s not the right tool for a half-acre sprawl — the 14-inch deck and 1/8-acre range make that clear. But within its intended territory, the WG779 executes confidently and consistently. If you’re managing a small yard and want to leave the gas era behind permanently, this is the mower we’d recommend without hesitation.
