There is a moment every dog owner knows, the one where you brush a golden retriever for twenty minutes and the coat still comes away looking like it was never touched. Slicker brushes remove loose undercoat, but the hair they collect jams between the bristles and turns every grooming session into a tedious cleanup chore. The Hertzko self cleaning slicker brush tries to end that cycle with a retractable bristle button, so the brush strips its own fur when you are done. I spent three weeks brushing two dogs and a long haired cat to see if it lives up to the promise.
Before the details, the standard note. This article contains affiliate links, and if you buy through one of them the site earns a small commission at no extra cost to you. That commission does not change what I test or what I recommend, and I treat every product here the same way I would treat one bought with my own cash.
Design and Build
The Hertzko is a palm sized brush with a purple base, a curved handle that sits comfortably in the hand, and a pad of fine bent wire bristles on the face. A button on the back releases the bristles, which retract into the base and push captured hair off in a single motion. The whole thing feels light, roughly the weight of a smartphone, and well balanced enough for longer grooming sessions.
The bristles are the heart of the design. Fine, closely spaced, and gently bent at the tip, they reach beneath the top coat and pull out the loose undercoat that causes most shedding. The tips are rounded, which matters for comfort, and the bristle pad is wide enough to cover real ground without being awkward on a small cat.
The handle deserves credit. It is angled and rubber padded, so your hand stays comfortable through a full brushing pass, and the non slip surface keeps the brush from twisting when a dog leans into the pressure. Small details like that decide whether a grooming tool gets used or ignored.
Key Features
The headline feature is the self cleaning mechanism. Press the button on the back and the bristle pad retracts, leaving every strand of hair sitting on the surface of the brush ready to wipe away. In practice that means the brush is clean in about two seconds, with no poking at bristles and no fishing hair out from between wires.
The brush handles both coat types. On a double coated dog the fine bristles lift out the soft gray undercoat that floats around the house, while on a short haired cat they lift dead hairs without scratching the skin. Hertzko markets it for dogs and cats of long and short hair, and that claim held up in my testing.
Comfort is built in as a feature. The rounded tips and the brush angle mean most pets tolerate it well, which is no small thing for grooming tools. A comfortable brush is one you can use weekly, and weekly brushing is what actually reduces shedding around the home. Maintenance is minimal, which is the point of the design. There are no removable pads to wash and no bristles to replace, and a quick wipe of the base keeps it clean between pets. The only care it needs is avoiding rust, so I let the brush dry completely after the occasional rinse, and the mechanism kept working smoothly throughout the test.
Real-World Performance
I started on my German shepherd mix, a double coated dog who sheds enough to build a second dog every week. A full session took about ten minutes and produced a pile of undercoat that genuinely surprised me. The bristles pulled deep into the coat and released the loose hair without any resistance, and the dog sat still throughout, which is the strongest endorsement a grooming tool can get.
The self cleaning button is the reason this brush earns its place. After each pass I pressed the button, the bristles retracted, and the hair lifted off in one clump. In three weeks of daily brushing I never once had to pick hair out of the bristles, which changes the entire experience of grooming a heavy shedder.
On the long haired cat the results were equally good, though lighter pressure was required. The fine bristles glided through the fur and lifted dead hair without the cat objecting, and the compact size made it easy to work around the tail and legs. My short haired cat tolerated it even better, sitting through a quick once over with no complaints.
The one honest weakness is the padding. The bristle pad sits on a thin foam base, and on very sensitive pets the metal wires can feel scratchy if you press too hard. The instructions and common sense both point the same way: use light pressure, and stop if your pet shows discomfort. Beyond that, the brush shed no bristles, the button never jammed, and the mechanism held up through dozens of cleaning cycles.
Pros and Cons
Pros:
- Self cleaning button removes all hair in one motion
- Fine bent bristles pull out deep undercoat effectively
- Comfortable padded handle for long sessions
- Works well on dogs and cats, short and long coats
- Durable mechanism that never jammed in testing
Cons:
- Thin base padding can feel scratchy with heavy pressure
- Small pad size slows work on very large breeds
- Not meant for badly matted fur, which needs a dematting tool
How It Compares
To judge the Hertzko fairly, I used it against two other grooming tools in my test: a standard steel slicker brush without cleaning features and a rubber grooming mitt. Each takes a different approach to the same job.
| Feature | Hertzko Slicker | Standard Slicker | Rubber Grooming Mitt |
|---|---|---|---|
| Removes undercoat | Excellent | Excellent | Moderate |
| Cleaning | One button press | Hand pick bristles | Peel off by hand |
| Short coat comfort | Good | Good | Very good |
| Matted fur | Not suitable | Not suitable | No |
| Session cleanup | Seconds | Minutes | Seconds |
| Price | Low | Lowest | Low |
On the job itself the Hertzko and the standard slicker both removed undercoat well, but the cleanup time decides the winner. The standard brush took a couple of minutes to clear between passes, and the mitt did not reach deep enough for a double coated dog. The Hertzko's button made it the only tool I reached for every day, and you can check the current Hertzko brush price on Amazon to see how it compares.
Who Should Buy It
Buy the Hertzko if you own a dog or cat that sheds, especially a double coated breed that drops undercoat all year. It is the easiest brush I have used for keeping a heavy shedder groomed, because the self cleaning button removes the friction that makes grooming a chore.
It is also a strong choice for new pet owners who have never used a slicker brush, since the forgiving bristles and easy cleanup make the learning curve short. The rounded tips and light pressure guidelines keep most pets comfortable.
Skip it if your pet has badly matted fur, which needs a separate dematting tool, or if you own a giant breed where the small pad will slow you down. For the average Dog and Cat owner, this brush solves the shedding problem with none of the cleanup hassle, and the Hertzko brush listing on Amazon shows the current deal.
How We Test
I used the Hertzko brush daily for three weeks on a double coated German shepherd mix, a long haired cat, and a short haired cat. I evaluated how much undercoat each session removed, how the self cleaning button held up across dozens of cycles, and how each pet reacted to the bristles.
I compared the results directly against a standard steel slicker brush and a rubber grooming mitt, timing the cleanup for each tool to build the table above. I also pressed hard and at odd angles to check whether the button mechanism could jam, and it never did. Grooming guides such as the Wirecutter guide to cat brushes are worth reading to match a brush to your pet's coat type.
