Sun Joe AJ801E Electric Lawn Dethatcher & Scarifier Review: Transform Your Lawn with Power and Precision

 





A healthy, vibrant lawn is the dream of every homeowner. However, keeping your grass lush and green requires more than just regular mowing and watering. One of the most overlooked yet critical lawn maintenance tasks is dethatching and scarifying, and that's exactly where the Sun Joe AJ801E Electric Lawn Dethatcher & Scarifier shines. Designed for heavy-duty performance, this compact yet powerful gardening tool is ideal for anyone serious about revitalizing their yard.


Key Features at a Glance

  • 12-amp electric motor delivers consistent, high-powered performance

  • 12.6-inch working width covers ground quickly and efficiently

  • 5-position depth control allows customized dethatching or scarifying

  • AirBoost technology improves thatch pickup with spring steel tines

  • 8-gallon collection bag for easy cleanup and debris removal

  • Two-in-one functionality: Dethatcher and scarifier combined in one device


Unboxing and Assembly

Out of the box, the Sun Joe AJ801E is relatively lightweight and easy to assemble. Most users can set it up in under 20 minutes with basic tools. The handle folds easily, making it simple to store in a garage or shed. It includes both dethatcher and scarifier attachments, which can be swapped depending on the lawn’s needs.

The black color with green accents gives it a professional, rugged look—visually reflecting its robust performance.


Performance & Operation

Equipped with a powerful 12-amp motor, the AJ801E makes quick work of even large or neglected lawns. The motor delivers steady torque that powers through compacted soil, dead grass (thatch), moss, and organic debris. Whether you're revitalizing a patchy lawn or maintaining an already healthy one, this machine delivers excellent results.

The 12.6-inch clearing width may seem modest, but it strikes a perfect balance between maneuverability and coverage. It’s wide enough to reduce the number of passes while still being nimble enough for tighter corners or around flower beds and trees.


Dethatching vs. Scarifying: What’s the Difference?

  • Dethatching involves removing the layer of dead grass and debris (thatch) that builds up between your soil and fresh grass. This layer can choke your lawn over time by blocking air and nutrients.

  • Scarifying digs a little deeper, cutting into the soil to promote better water absorption and airflow at the root level. It’s more aggressive and better suited for lawns that need serious renovation.

The AJ801E handles both tasks excellently thanks to its interchangeable attachments and 5-position height adjustment, letting you control how deep the tines penetrate.


Customizable Depth Control

The depth control lever allows you to choose from five height settings, ranging from gentle dethatching to deep scarification. This versatility is one of the AJ801E’s strongest features—it allows you to adapt the intensity based on your lawn’s current condition.

For regular seasonal maintenance, the lighter settings will do the job. For more intense turf renovation, a deeper setting can be selected. Just be cautious not to over-scarify, as this can damage healthy grass if used too aggressively.


AirBoost Technology: What It Does

Sun Joe’s AirBoost technology enhances tine performance with durable spring steel that stays sharp over time. This technology helps maximize pickup of embedded thatch and improves air circulation at the grass root level, promoting quicker recovery and fuller growth.

Compared to manual rakes or less powerful machines, the AJ801E lifts far more debris in a shorter amount of time. The spring steel tines are rugged and resistant to wear, allowing for longer-term use without the need for frequent replacement.


Convenient Debris Collection

A highlight of this tool is the 8-gallon detachable collection bag. It efficiently collects thatch and debris, so you don’t have to spend extra time raking afterward. For large lawns, you may need to empty it a few times during use, but the process is quick and clean.

If you prefer to leave the debris on the ground temporarily (for later composting or raking), you can also run the machine without the bag attached.


Suggested Use Cases

  • Spring & Fall cleanup: Essential for seasonal lawn rejuvenation

  • Post-winter repair: Great for reviving grass after snow or frost damage

  • Before reseeding: Helps prepare the soil for better seed penetration

  • General lawn care: Keep your yard healthy by dethatching 1–2 times per year
