The Worx WG779E is a compact 40V cordless lawn mower powered by two 20V PowerShare batteries. I use mine regularly in gardening work, where its low weight, 34cm cutting width and IntelliCut power adjustment make it particularly useful for small to medium lawns.
Its main limitations are the 30L grass bag and modest size, so it is better suited to routine mowing than large or heavily overgrown lawns. But for regular domestic lawn care — especially if you already own Worx PowerShare batteries — it is an easy mower to live with.

What Is the Worx WG779E Like to Use?
Cutting Performance & IntelliCut
The WG779E is best suited to routine mowing on small to medium lawns. Its 34cm cutting width is compact enough to move easily around beds, paths and tighter garden spaces, while still covering ground efficiently enough for regular domestic use.
The mower’s IntelliCut system automatically adjusts power when it meets denser grass, which helps it maintain a more consistent cut without running at maximum output all the time. In normal use, this gives it enough flexibility for maintained lawns and patches where the grass has grown a little thicker.
Its limits are fairly clear, though. The WG779E is not the mower I would choose for large areas or badly overgrown grass, where the smaller deck and battery demand become more noticeable.
Weight & Manoeuvrability
One of the WG779E’s biggest strengths is how easy it is to move around. The compact body and relatively low weight make it straightforward to steer around obstacles, reposition between lawn sections and carry when needed.
That suits the kind of smaller gardens where a larger mower can feel cumbersome. The folding handle also helps with storage, particularly if shed or garage space is limited.
For lawn edges and areas the mower cannot reach, see my Worx WG163E grass trimmer review.
Cutting Height & 34cm Deck
The mower offers six cutting-height settings from 20mm to 70mm, allowing you to adjust the finish depending on lawn condition and time of year.
The 34cm deck is a good fit for small and medium lawns because it keeps the machine nimble and easy to control. The trade-off is that larger lawns take more passes than they would with a wider mower.
For routine mowing, I think that balance works well: it prioritises easy handling over maximum coverage.
Grass Collection
The 30-litre grass bag is adequate for smaller lawns, but it is one of the WG779E’s clearest compromises.
When the grass is growing quickly or has been left longer between cuts, the bag fills noticeably faster and needs emptying more often. For regular maintenance this is manageable, but on larger lawns it becomes more of an interruption.
Battery & Worx PowerShare
The WG779E runs on two 20V Worx PowerShare batteries, combining them to provide the mower’s 40V power supply.
That is particularly useful if you already own other Worx tools, because the same battery platform can be shared across the wider range instead of keeping separate batteries and chargers for each machine.
Runtime depends on the batteries fitted, grass length and how often IntelliCut has to increase power. For normal mowing on smaller lawns, the setup is well suited to the job, while larger or heavier cutting sessions will naturally use the batteries faster.
How the Worx WG779E Compares
The WG779E sits in a useful middle ground among compact cordless mowers. Its strengths are the 34cm deck, IntelliCut power adjustment and PowerShare battery system, while some rivals offer a larger grass box or brushless motor.
| Model | Power | Cutting Width | Grass Bag | Weight | Best For | Main Trade-Off |
|---|---|---|---|---|---|---|
| Worx WG779E.2 | 40V PowerShare | 34 cm | 30 L | 11.1 kg | Small–medium lawns, Worx users | Smaller grass bag |
| Bosch ROTAK18V-32 | 18V | 32 cm | 35 L | — | Compact lawns and easy storage | Smaller cutting width |
| Greenworks G40LM35 | 40V | 35 cm | 40 L | 15 kg | Medium lawns and larger collection | Heavier machine |
| Ryobi RY18LMX40A | 18V ONE+ | 40 cm | 50 L | 18 kg with battery | Wider coverage and larger lawns | Much heavier |
Worx currently lists the WG779E.2 with a 34cm deck, 30L grass bag, six cutting heights and an 11.1kg weight, while the Bosch ROTAK18V-32 uses a narrower 32cm deck and 35L grass box.
The Greenworks offers a slightly wider 35cm cut and 40L collector, but at 15kg it is noticeably heavier. Ryobi’s 40cm ONE+ mower gives substantially more cutting width and collection capacity, but is a much larger and heavier machine.
For my own use, the WG779E makes most sense where easy handling matters more than maximum coverage. Its smaller deck and 30L bag are limitations on bigger lawns, but they also help keep the mower compact and manoeuvrable — and PowerShare compatibility makes it particularly attractive if you already own Worx tools.
If moss and thatch are the problem rather than grass length, see my Worx WG855E.9 scarifier review.
Worx WG779E FAQs
Small to medium domestic lawns.
Runtime depends on grass length, conditions and how often IntelliCut increases power. With the supplied 2.0Ah batteries, Worx rates the mower for up to around 230m² per charge under suitable conditions.
Yes within reason, with IntelliCut helping, but it is not intended for badly overgrown lawns.
The WG779E offers six cutting-height settings from 20mm to 70mm, covering everything from a shorter summer cut to a higher finish when conditions require it.
Yes, compatible PowerShare tools.
Fine for small lawns; fills frequently on larger or fast-growing areas.
Final Verdict: Is the Worx WG779E Worth Buying?
For small to medium lawns, the Worx WG779E is a practical cordless mower. Its low weight, compact 34cm deck and IntelliCut power adjustment make it particularly easy to use for regular domestic lawn maintenance.
I find its biggest strengths are manoeuvrability and simplicity. The main compromises are the small 30L grass bag and narrower cutting width, which become more noticeable on larger lawns or when the grass has been left too long.
Verdict: A very useful compact cordless mower for routine lawn care, particularly if you already use Worx PowerShare batteries.
