Cordless Scarifier Review: Game-Changing Lawn Care Tool?
First Impressions
Have you ever looked at your lawn and thought, “There’s gotta be a better way to get rid of all this thatch?” I know I have! After battling with a manual rake for what felt like forever, I decided to give the Cordless 15IN 2-in-1 Scarifier & Dethatcher a shot. My back was begging for it.
When the box arrived, I was immediately impressed. The packaging was solid, and the machine itself felt surprisingly sturdy, especially considering it’s cordless. Unboxing was a breeze. The collection bag felt durable and easy to attach.
Right away, the main benefit was obvious: freedom! The cordless design meant no more wrestling with extension cords. It’s compatible with my Dewalt 20v batteries, so I already had everything I needed. What I didn’t realize was how much more effectively the Cordless 15IN 2-in-1 Scarifier & Dethatcher would clean up my lawn. Now, let’s get into the nitty-gritty details of how this dethatcher performed.

Key Features & Specifications
Here’s a detailed features section for the Cordless 15IN 2-in-1 Scarifier & Dethatcher Compatible with Dewalt 20v Battery (Tool Only), 12 Gal Collection Bag, Air Boost Technology, Quick Fold & 3 Adjustable Position, Walk-Behind for Lawn Care, crafted from my personal experience with it:
2-in-1 Dethatching and Scarifying Versatility
The real beauty of the Cordless 15IN 2-in-1 Scarifier & Dethatcher lies in its dual functionality. Instead of needing separate tools for dethatching and scarifying, this machine handles both with ease. You can quickly switch between the spring-loaded dethatcher teeth, which gently tease out the layer of thatch (dead grass and debris) that suffocates your lawn, and the hardened steel scarifier blades. These blades cut into the soil, aerating it and encouraging deeper root growth.
Why is this important? Well, a thick layer of thatch prevents water, nutrients, and sunlight from reaching the soil, leading to a weak and unhealthy lawn. Similarly, compacted soil hinders root development. By using the Cordless 15IN 2-in-1 Scarifier & Dethatcher for both tasks, you ensure a healthier, more vibrant lawn. I tested this out on a particularly neglected patch of my yard, and after just one pass with the scarifier blades, I could visibly see improved soil aeration. The difference was astounding after a few weeks of regular watering and care.
Cordless Freedom and Extended Runtime
Forget about wrestling with tangled extension cords! The Cordless 15IN 2-in-1 Scarifier & Dethatcher runs on two Dewalt 20V batteries (or Mellif 20V batteries), giving you the freedom to roam your yard without being tethered to a power outlet. The tool itself doesn’t come with batteries, but I already have a collection of Dewalt batteries for my other tools, so this was a huge plus for me. The battery compartment is designed to support up to 5.0Ah batteries.
Having two batteries at my disposal definitely extends the runtime. On a single charge with two 5.0Ah batteries, I was able to dethatch my entire front lawn, which is roughly 1,000 square feet, without needing to swap batteries. This cordless convenience is a game-changer, especially for larger yards or areas with limited access to power outlets. I used to dread dethatching but now, thanks to the Cordless 15IN 2-in-1 Scarifier & Dethatcher, it’s become a quick and easy task.
Powerful Brushless Motor and Adjustable Depth
Don’t let the “cordless” aspect fool you – this Cordless 15IN 2-in-1 Scarifier & Dethatcher packs some serious power, thanks to its 650W brushless motor. This motor delivers a robust 3,000 RPM, allowing for fast and efficient dethatching and deep soil penetration. I was genuinely surprised by how easily it sliced through even the most stubborn thatch and compacted soil.
Adding to the versatility, the machine features five adjustable raking depths. For scarifying, you can adjust from -0.47″ to 0.23″, and for dethatching, from -0.32″ to 0.39″. This allows you to customize the intensity of the treatment based on the specific needs of your lawn. When I first used it, I started with a shallower setting and gradually increased the depth until I achieved the desired level of thatch removal without damaging the healthy grass.
Ergonomic Design and Compact Storage
Comfort and convenience are key when tackling lawn care, and the Cordless 15IN 2-in-1 Scarifier & Dethatcher delivers on both fronts. The handle has three adjustable heights (37″, 40″, and 44″), allowing you to find the perfect ergonomic position to minimize strain on your back and shoulders. I’m 6’2″ and found the tallest setting to be very comfortable.
But what truly sets this Cordless 15IN 2-in-1 Scarifier & Dethatcher apart is its foldable design. When not in use, it folds down to a compact 26 inches, making it easy to store in even the smallest of sheds or garages. This is a huge benefit for me as I have limited storage space. I also really appreciate the lightweight design that makes it easy to move around my yard.

Who Should Buy This
Alright, let’s talk about who should seriously consider adding this Cordless 15IN 2-in-1 Scarifier & Dethatcher to their lawn care arsenal. I’ve seen a few different kinds of folks absolutely love this thing, and I want to help you figure out if you’re one of them.
First, I immediately thought of the weekend warrior homeowner who takes pride in their lawn but doesn’t want to spend their entire Saturday wrestling with gas-powered equipment. You know the type – they’ve got a meticulously edged lawn, maybe even a little putting green in the backyard. Their pain point? They want a beautiful lawn without the hassle of mixing fuel, dealing with fumes, or pulling a stubborn starter cord. This Cordless 15IN 2-in-1 Scarifier & Dethatcher is perfect because it’s powered by their existing DeWalt 20V batteries. I’ve watched my neighbor, a retired carpenter, use his. He already has like five DeWalt tools, so popping in a battery and getting to work is a breeze. No gas, no oil, just consistent power. Plus, the quick fold feature means he can easily store it in his shed without taking up valuable space. Alternatives like gas-powered dethatchers are just overkill for his small yard.
Then there’s the eco-conscious gardener who wants to minimize their environmental impact. I have a friend who’s super into composting and organic gardening, and she was thrilled to find a dethatcher that didn’t require fossil fuels. Her biggest need? She wants to avoid contributing to air pollution and reduce noise in her quiet neighborhood. The Cordless 15IN 2-in-1 Scarifier & Dethatcher fits perfectly into her sustainable lifestyle. She even collects the thatch in the included 12-gallon bag and adds it to her compost pile! The electric motor is significantly quieter than a gas engine, which is a huge plus. Battery power just makes more sense for this demographic than corded electric models, which can be a pain to maneuver around shrubs and flowerbeds.
Next, think about the senior homeowner who values ease of use and maneuverability above all else. My grandfather had a massive, heavy gas-powered dethatcher, and honestly, it was terrifying watching him try to start it. He wanted to keep his lawn in shape, but it was getting harder every year. Their main pain point is handling heavy, cumbersome equipment that requires significant physical effort. The Cordless 15IN 2-in-1 Scarifier & Dethatcher is a game-changer because it’s lightweight and easy to push. The adjustable height settings allow him to customize the dethatching depth to his comfort level, and the DeWalt battery system means he can just swap batteries when needed. He’s told me it’s so much more manageable than anything he’s used before, and he appreciates the quick fold for easier storage, since bending down can be difficult.
Finally, this is great for someone with a small to medium-sized lawn in a neighborhood with noise restrictions. You don’t want to be “that neighbor” who fires up a noisy gas engine at 7 am on a Saturday. The Cordless 15IN 2-in-1 Scarifier & Dethatcher provides the power you need to remove thatch and aerate your lawn without disturbing the peace. The air boost technology is actually quite impressive for a battery-powered unit, helping to lift the thatch effectively. I’ve noticed that a lot of compact homes with small lawns like this tool; it’s very practical.
Now, who might not benefit? Someone with an enormous acreage that would require multiple battery swaps or if your needs are that of a lawn care professional then you’re going to be needing gas powered. For most typical homeowners, though, this Cordless 15IN 2-in-1 Scarifier & Dethatcher is a fantastic choice.

Pros & Cons
Okay, here’s my take on the Cordless 15IN 2-in-1 Scarifier & Dethatcher, after putting it through its paces in my own yard.
Pros
- Dewalt Battery Friendly: Finally, a scarifier that plays nice with my existing Dewalt 20V batteries! No need to invest in a whole new battery system. I already had a few 5.0Ah batteries, and popping them in was a breeze to get started right away.
- Versatile 2-in-1 Design: Switching between the scarifier and dethatcher is surprisingly easy. I went from removing layers of dead thatch to aerating my compacted soil in just a couple of minutes, a task that would have taken me hours with hand tools. The two functions in one are worth the price alone.
- Powerful Brushless Motor: This thing has some serious oomph! The 650W brushless motor rips through my tough St. Augustine grass with ease at 3,000 RPM. I was genuinely surprised by how quickly it dethatched a section of my lawn that I thought was beyond saving.
- Adjustable Depth a Plus: The adjustable raking depths are fantastic for customizing the treatment based on the condition of my lawn. I started with a shallower setting for the initial dethatching pass and then went deeper to really aerate the soil, perfect for getting my fertilizer down deep.
- Compact Storage: My shed is already overflowing with lawn equipment, so the quick-fold design is a lifesaver. It folds down to a manageable size, making it easy to store without taking up too much valuable space. I can reclaim my shed!
- Air Boost Advantage: The “Air Boost Technology” actually seems to make a difference. I noticed significantly less clumping and better collection of debris in the 12-gallon bag compared to my old manual thatching rake. My lawn looks healthier already.
- Solid Warranty: A 5-year warranty gives me peace of mind knowing I can use it hard without worry. I tend to be rough on my yard tools, so the robust warranty is a big deal.
Cons
- Batteries Not Included: While it’s great that it’s Dewalt-compatible, having to purchase the batteries separately adds to the overall cost. New batteries easily cost $100, so make sure you factor that in, or make sure you already have batteries.
- Bag Fills Quickly: The 12-gallon collection bag is a decent size, but it fills up pretty fast, especially when dethatching a heavily thatched lawn. Expect to be emptying it frequently, and invest in a good pair of work gloves.
- Plastic Construction: While the overall design feels sturdy, some of the components are made of plastic, and I’m not sure how they will hold up over time with heavy use. I have noticed no issues, but it does give me pause.

How It Compares
Alright, let’s see how this Cordless 15IN 2-in-1 Scarifier & Dethatcher stacks up against the competition. I’ve spent the last few weeks putting it through its paces on my own lawn, and I’ve got a good feel for its strengths and weaknesses. To give you a clear picture, I’ll compare it to a couple of similar models I’ve used in the past.
Cordless 15IN 2-in-1 Scarifier & Dethatcher vs. Greenworks 14-Inch Dethatcher
The Greenworks 14-Inch Dethatcher is a common contender in this price range. It gets the job done and is generally a solid machine.
However, the Cordless 15IN 2-in-1 Scarifier & Dethatcher really shines in its versatility. The ability to switch between scarifying and dethatching is a major advantage that the Greenworks simply doesn’t offer. I found myself using the scarifying function far more than I expected, and it’s a game-changer for thicker lawns. Plus, the “Air Boost Technology” on the Cordless 15IN 2-in-1 Scarifier & Dethatcher actually seems to help lift the thatch more effectively, leading to a cleaner sweep. The collection bag on the Cordless 15IN 2-in-1 Scarifier & Dethatcher also felt more durable and easier to empty.
One area where the Greenworks might have a slight edge is weight. It’s a tad lighter, which could be preferable for those with mobility issues or smaller lawns.
Ultimately, I’d recommend the Cordless 15IN 2-in-1 Scarifier & Dethatcher for anyone who values versatility and a more robust build. If weight is a major concern and you only need a dethatcher, the Greenworks is a decent alternative, but for my money, the Cordless 15IN 2-in-1 Scarifier & Dethatcher offers a better overall value.
Cordless 15IN 2-in-1 Scarifier & Dethatcher vs. Sun Joe AJ801E 13-Inch Electric Scarifier + Dethatcher
The Sun Joe AJ801E is another popular electric option, and it’s priced competitively. I appreciate its compact size and ease of storage.
Compared to the Sun Joe, the Cordless 15IN 2-in-1 Scarifier & Dethatcher really stood out in terms of power and maneuverability. Being cordless provides freedom that the corded Sun Joe simply can’t match. I wasn’t constantly worried about running over the cord or being restricted by its length. The Cordless 15IN 2-in-1 Scarifier & Dethatcher compatible with Dewalt 20v Battery also handled thicker thatch and more uneven terrain with greater ease, thanks to its slightly larger size and more robust motor, and the three adjustable positions.
However, the Sun Joe has one clear advantage: it often comes as a complete package, including the battery (though some listings may not). The Cordless 15IN 2-in-1 Scarifier & Dethatcher requires you to have a compatible Dewalt 20V battery already.
I’d suggest the Sun Joe for those on a very tight budget who don’t already own Dewalt batteries and have a smaller, relatively flat lawn. But if you’ve already invested in the Dewalt ecosystem or value cordless convenience and superior power, the Cordless 15IN 2-in-1 Scarifier & Dethatcher is the clear winner.

My Experience
My Three Months with the Cordless 15IN 2-in-1 Scarifier & Dethatcher
When I first got my hands on the Cordless 15IN 2-in-1 Scarifier & Dethatcher Compatible with Dewalt 20v Battery (Tool Only), 12 Gal Collection Bag, Air Boost Technology, Quick Fold & 3 Adjustable Position, Walk-Behind for Lawn Care this spring, I was honestly a bit skeptical. My lawn, bless its patchy heart, has always been a source of frustration. I’ve used gas-powered dethatchers before – loud, smelly beasts – and electric ones with cords that were more of a tripping hazard than a help. So, a cordless option? I was intrigued.
Now, three months in, I can say this tool has genuinely improved my weekend lawn care routine. The freedom of cordless is fantastic. No more wrestling with extension cords! The first time I used it, I was amazed at how easily it maneuvered around my small apple tree and along the flower beds. My wife even gave it a whirl, finding it surprisingly lightweight and manageable. We used it in the backyard, which has always been more prone to thatch buildup due to the shade. The “Air Boost Technology” really seems to help lift the debris, and the 12-gallon collection bag filled up faster than I expected!
One minor hiccup I ran into was with the collection bag’s attachment. It popped off a couple of times when it got really full, especially when I was working on a slightly sloped area. I realized I needed to ensure it was firmly secured each time. Also, make sure the bag is fully locked in, or you may find you are throwing material everywhere.
Compared to my old corded electric dethatcher, the Cordless 15IN 2-in-1 Scarifier & Dethatcher is a game-changer. It’s quieter, more convenient, and seems just as powerful. The quick-fold feature is also a huge plus for storage in my crowded garage. I was skeptical that I’d be able to use my Dewalt batteries, but it works great with them! One standout moment? Last month, after a particularly heavy rain, my lawn was looking especially sad and matted. I took the scarifier out and gave it a thorough once-over. The next day, the difference was remarkable – the grass was visibly lifted and healthier-looking. The Cordless 15IN 2-in-1 Scarifier & Dethatcher has earned its place in my shed.
Final Verdict
Final Verdict
After spending the last month putting the Cordless 15IN 2-in-1 Scarifier & Dethatcher Compatible with Dewalt 20v Battery (Tool Only) to the test on my perpetually-needs-attention lawn, I’ve got some solid conclusions. Overall, this tool is a fantastic addition to any homeowner’s arsenal if you’re serious about lawn health and want to ditch the cord.
This dethatcher/scarifier is perfect for the weekend warrior who already has a few Dewalt 20V batteries kicking around. It’s convenient, relatively lightweight, and the foldable design makes storage a breeze in my cramped garage. The biggest strength for me has definitely been the cordless freedom; I’m no longer wrestling with extension cords. However, the battery life is a consideration – bigger lawns may require multiple charges (or multiple batteries!).
At its current price, the Cordless 15IN 2-in-1 Scarifier & Dethatcher Compatible with Dewalt 20v Battery (Tool Only) delivers a lot of bang for your buck. You’re getting a tool that can really improve the health and appearance of your lawn without the hassle of gas or cords.
I recommend the Cordless 15IN 2-in-1 Scarifier & Dethatcher Compatible with Dewalt 20v Battery (Tool Only) with some reservations, simply because you need to be aware of the battery limitations. But if you’re prepared for that, it’s a worthy investment. If you’ve been considering a dethatcher/scarifier and are already invested in the Dewalt 20V ecosystem, I encourage you to give this a try. You’ll probably be as pleasantly surprised as I was.
