Why a Scarifier & Aerator Is Essential
A healthy, green lawn isn’t just about mowing—it’s also about what happens beneath the surface. Over time, moss, thatch, and compacted soil build up. This blocks air, water, and nutrients from reaching the roots. The result is grass that looks thin, weak, and patchy. That’s why using a lawn scarifier and aerator is essential for long-term lawn health.
What Does Scarifying Do?
Scarifying—sometimes called dethatching—cuts into the surface layer and removes moss, weeds, and thatch. This process helps the lawn breathe and reduces the build-up of debris that suffocates healthy growth.
Why Aerating Matters
Aerating opens the soil, improves drainage, and gives roots the space they need to grow deeper and stronger. This step is vital for boosting nutrient uptake and supporting resilient grass.
Common Questions Gardeners Ask
- Is scarifying better than dethatching? They are similar, but scarifying usually goes deeper and removes more material.
- Should I scarify or aerate my lawn? Ideally, do both. Scarifying clears the surface, while aerating strengthens the soil and encourages deeper root growth.
The Payoff
The result is clear: less moss, fewer bald patches, and a lawn that looks lush and well cared for. With the right cordless scarifier and aerator, the job becomes faster, cleaner, and far less tiring than raking by hand.
Key Features to Look For in a Cordless Scarifier
Before diving into the Worx WG855E.9 review, it helps to understand what makes a good cordless lawn scarifier and aerator. Not all machines deliver the same results, and the right features can make the difference between a patchy lawn and one that looks thick and healthy.
Essential Features
- Brushless Motor – More efficient, longer-lasting, and more powerful than brushed motors. This is crucial for tackling stubborn moss, heavy thatch, and compacted soil.
- Cordless Convenience – Forget about extension leads and tangled cables. A battery powered scarifier gives you freedom to move easily across the garden.
- Working Width – Around 36 cm is ideal. It covers small to medium lawns quickly while staying easy to manoeuvre.
- Height/Depth Adjustment – Multiple depth settings (from +6 mm down to -9 mm) let you choose between light moss removal, dethatching, and deeper scarifying for aeration.
- Interchangeable Rollers – Switching between a scarifier blade and aerator spring effectively gives you two tools in one.
- Collection Bag – A 40L collection bag saves time during clean-up, especially when removing thick layers of moss and thatch.
- Lightweight Design – A lightweight scarifier that’s easy to use makes longer jobs less tiring and more manageable.
Why This Matters
If these features are on your checklist, the Worx cordless scarifier with collection bag ticks every box. It’s a versatile and practical option for UK gardeners who want professional-level results at home.
Worx WG855E.9 Review – 40V Cordless Scarifier & Aerator
The Worx WG855E.9 Nitro cordless scarifier and aerator is built for gardeners who want professional lawn care results without the hassle of petrol engines or trailing cables. In this hands-on Worx scarifier review, I’ll cover how it performs in real conditions and whether it deserves a spot in your shed.
Performance
The 40V brushless motor delivers consistent power, even when tackling heavy moss, thick thatch, or compacted soil. With a 36 cm working width, this cordless lawn scarifier and aerator can cover small to medium UK gardens quickly—up to around 400 m² on a 4–5Ah battery. It makes lawn renovation far less time-consuming than manual raking.
Ease of Use
At just over 10 kg, the WG855E.9 is light enough to push easily, even across uneven lawns. The tool-free roller swap between scarifying blades and aerating springs is a real advantage, offering flexibility without the need for extra tools.
Adjustability
The 4-position depth control (from +6 mm to -9 mm) allows you to customise how aggressive the treatment is. Shallow settings work well for light moss removal and dethatching, while deeper settings aerate the soil and promote stronger root growth.
Build Quality

How to Use & Maximise Results with the Worx WG855E.9
Getting the most out of a cordless lawn scarifier and aerator comes down to timing, technique, and proper aftercare. When used correctly, the Worx WG855E.9 cordless scarifier can turn a mossy, tired lawn into one that looks thick, green, and healthy.
Best Times to Scarify
- Spring (March–April): Clears away winter moss and thatch, preparing the lawn for strong new growth.
- Autumn (September–October): Removes summer build-up and helps the lawn recover before winter sets in.
Pre-Scarifying Tips
- Do you cut grass before scarifying? Yes. Mow the lawn short (around 2–3 cm) so the blades reach the thatch effectively.
- Should you apply moss killer before scarifying? For heavy moss, apply a treatment 1–2 weeks beforehand for the best results.
- Should you remove weeds before scarifying? Yes. Weeds can snag in the rollers and reduce efficiency, so remove them first.
How to Use the Worx WG855E.9
- Select the right roller—scarifier blade or aerator spring—depending on your lawn’s needs.
- Set the depth:
- Shallow (+6 mm to -3 mm): Best for light moss removal or gentle dethatching.
- Deeper (-6 mm to -9 mm): Ideal for aerating compacted soil and boosting root health.
- Work in neat, parallel lines, overlapping slightly for even coverage.
- Empty the 40L collection bag often to maintain strong performance.
Aftercare
- What to do after scarifying a lawn? Collect leftover debris, overseed bare patches, and water thoroughly.
- Apply a balanced lawn fertiliser to encourage fast regrowth and keep grass resilient.
Pro Tip
Scarify little and often rather than going too deep in one pass. This helps the lawn recover faster and keeps it healthier long term.
