The Worx WG855E.9 is a 40V cordless scarifier and aerator designed for small to medium lawns. I use it in my gardening work for removing moss and thatch without the cable management of a corded machine, and the interchangeable scarifying and aerating rollers make it useful for seasonal lawn maintenance.
Its main compromises are the tool-only setup, relatively short runtime and small collection bag. But if you already own Worx PowerShare batteries and want a compact cordless machine for routine lawn renovation, it is a practical option.

What Is the Worx WG855E.9 Like to Use?
Scarifying Performance
The Worx WG855E.9 has plenty of power for routine lawn renovation, with its 40V brushless motor handling moss, thatch and compacted material well on small to medium lawns.
In use, it feels much easier than working with a manual scarifier, particularly when a lawn has built up a noticeable layer of moss. The 36cm working width also gives a good balance between covering ground efficiently and keeping the machine easy to manoeuvre.
It is best treated as a domestic lawn-care machine rather than something for heavily neglected or very large areas. Where the lawn is particularly dense with moss or thatch, a couple of lighter passes generally make more sense than trying to remove everything at maximum depth in one go.
Aerating & Roller Change
One of the WG855E.9’s strongest features is its 2-in-1 roller system. It includes a scarifying blade roller for removing moss and thatch, plus a spring-tine aerating roller for lighter surface work.
Changing between them is tool-free, so the same machine can be used for deeper seasonal scarifying or gentler lawn maintenance without needing a second tool.
That flexibility is one of the main reasons the WG855E.9 works well as an all-round lawn-care machine rather than simply a once-a-year scarifier.
Depth Adjustment
The four-position depth control lets you adjust how aggressively the rollers work, from lighter surface treatment through to deeper scarifying.
This is useful because not every lawn needs the same level of treatment. I would start shallow and only move deeper where the moss or thatch genuinely needs it — going too aggressively in one pass can leave the lawn looking unnecessarily rough.
Weight & Handling
At just over 10kg, the WG855E.9 is relatively easy to push and reposition around a domestic lawn. The cordless design also removes the biggest inconvenience of many electric scarifiers: having to work around an extension lead.
The main practical annoyance is the 40-litre collection bag. Scarifying can remove a surprising amount of moss and debris, so it fills quickly when working on a heavily thatched lawn.
For lighter maintenance it is perfectly usable, but on a moss-heavy lawn expect to stop and empty it regularly.
Battery & Runtime
The WG855E.9 uses the Worx PowerShare system, combining compatible batteries to provide its 40V power supply. That makes it particularly attractive if you already own other Worx tools and batteries.
Runtime is one of its main limitations, especially when scarifying deeply or working through dense moss. For a small or medium lawn this is manageable, but larger areas may require a second set of charged batteries.
It is also commonly sold tool-only, so anyone new to the Worx platform should factor the cost of suitable batteries and a charger into the overall price.
How the Worx WG855E.9 Compares
| Model | Power | Working Width | Best For | Main Trade-Off |
|---|---|---|---|---|
| Worx WG855E.9 | 40V cordless | 36 cm | Small–medium lawns, Worx users | Limited battery runtime |
| Bosch AVR 1100 | Corded | 32 cm | Smaller lawns, regular scarifying | Extension cable |
| Einhell GE-SA 36/35 Li | Cordless | 35 cm | Budget cordless option | Battery setup/capacity |
| Makita UV3600 | Corded | 36 cm | Larger or more intensive jobs | Heavier, corded design |
The WG855E.9 sits in a useful middle ground: it offers the freedom of a cordless machine with a 36cm working width and interchangeable scarifying and aerating rollers. Corded models remain better suited to long, uninterrupted sessions, while the Worx makes most sense for smaller lawns and gardeners already using PowerShare batteries.
After scarifying, regular mowing helps keep the lawn recovering evenly. See my Worx WG779E cordless mower review for the mower I use for routine lawn maintenance.
Worx WG855E.9 FAQs
No. The WG855E.9 is a tool-only model, so batteries and a charger are not included.
Runtime varies with battery capacity, scarifying depth and lawn conditions. Deeper scarifying through heavy moss or thatch will use more power, so larger lawns may require a second set of charged batteries.
Yes. It uses two interchangeable rollers: a scarifying blade roller for removing moss and thatch, and a spring-tine aerating roller for lighter surface work.
It is best suited to small and medium lawns. The 36cm working width is practical for domestic gardens, while battery runtime makes it less convenient for very large areas or long, uninterrupted renovation work.
The WG855E.9 has four depth positions, allowing you to start with a lighter treatment and increase the depth where more aggressive moss or thatch removal is needed.
The 40-litre collection bag is adequate for routine lawn maintenance, but scarifying can remove a surprising amount of moss and debris. On a heavily thatched lawn, expect to empty it regularly.
Final Verdict: Is the Worx WG855E.9 Worth Buying?
For small to medium lawns, the Worx WG855E.9 is a practical cordless scarifier and aerator. The interchangeable rollers, four depth settings and brushless motor give it enough flexibility for routine moss removal, thatch control and seasonal lawn renovation.
I find its biggest strengths are the cordless handling and 2-in-1 roller system. The compromises are runtime, the small collection bag and the fact that it is commonly sold tool-only, so it makes the most sense if you already own compatible Worx PowerShare batteries.
Verdict: A strong cordless option for routine lawn renovation, particularly for existing Worx users with small to medium lawns.
