I often like to say, that every job has its tool. If you use the right tool for the job you make your life easier and the results speak for themselves.
If you have a Karcher pressure washer, you’ve already made a good decision to take control of your home cleaning needs, avoiding the need to hire a professional.
Take it a step further and outfit your power washer with the best pressure washer accessories for every type of job you have before you.
In this article, I’ll review the best Karcher attachments by category so you know you’re getting the right tool for the job. Since the accessories are made specifically for Karcher products, you can use most of them for any model pressure washer, K2, K3, K4, K5 or K7.
I updated the article in 2024, but to be honest, I haven’t changed that much, just ensured, that all items are still available as some of the accessories were not available anymore.
Best Karcher Pressure Washer Accessories
- Most Useful – Kärcher FJ6 Foam Jet Nozzle
- Best For Patios – Kärcher T 5 Patio Cleaner
- Best For General Car Cleaning – Kärcher 2643-233.0 Soft Washing Brush
- Best for Wheel Cleaning & Detailing- Kärcher 26432340 Alloy Wheel Wash Brush

1. Most Useful – Kärcher FJ6 Foam Jet Nozzle
Pros
- Effortlessly applies soap
- Can also be used for varnishing
- Small and easy store
Cons
- Needs removed again to spray water from
Whether it is a spring cleaning job to get rid of a long winter’s residue on your car, or you live in a rural area that keeps your car in perpetual mud mode, you definitely need to give your car a soak in a foam broth.
Use this foam jet nozzle to coat your car with the detergent of your choice. Many Karcher models have an integrated detergent system, which is convenient until you want to use a different detergent than the Karcher brand. This foam jet then gives you more options to clean your car.
A 0.6-litre capacity is more than enough for even the hardest to clean residue on your car.
It can be used for soaps, varnishes or other cleaning products.
2. Best For Patios – Kärcher T 5 Patio Cleaner
Pros
- Adjustable power
- Adjustable nozel height
- Walled to keep you dry
- Can be used vertically to clean walls and doors
Cons
- Needs cleaned out to prevent clogging
- Need to move slowly for a thorough clean
It doesn’t matter what kind of surface you have on your patio or driveway. The T5 Patio Cleaner is the best attachment to clean just about any surface quickly, effectively and safely.
With an adjustable knob, you can control the pressure for the type of surface you are cleaning. Making it ideal for cleaning wood decking or concrete equally well. Not only that, but gravel is also washable thanks to a protective grill.
The shape is angled as a triangle for getting into corners and an extra power nozzle cleans right to the edges.
You’l also like that it’s got a handle on the base so you can use it vertically to clean walls and garage doors, handier than you’d think.
3. Best For Car Cleaning – Kärcher 2643-233.0 Soft Washing Brush
Pros
- Bristles won’t damage or scratch car paint
- Rubber round edges so the body of the brush doesn’t scratch
- Wide head for fast cleaning
- Can get a deeper clean
Cons
- Bristles need to be cleaned out
Soft, yet sturdy, bristles coupled with the high-pressure water make for a must-have car washing accessory if you have any model Karcher pressure washer.
Attached to a detergent system, you are able to give your car the same treatment as a professional car detailer.
The wide brush gives a clean sweep of a larger area making quick work of the job. Getting the clean up done in less time means you’re more likely to use it often, resulting in a sparkling car that feels good to drive.
The edges of the brush head are topped with ribbed rubber to avoid any damage to the car if you accidentally bang it. That’s a detail that helps to feel confident that Karcher cares about your cleaning experience.
It can be attached directly to the trigger gun or for more reach, an extension rod.
4. Best for Wheel Cleaning – Kärcher Alloy Wheel Wash Brush
Pros
- Firmer bristles for stubborn wheel dirt
- Uniform water distribution
- Easy storage
Cons
- Still quite large for small hard to reach areas
Gentle on wheels, you should have this tool in your kit to get that stubborn brake dust off of your expensive (or not!) wheel rims.
The bristles are hard enough to remove the grime, but gentle enough to not damage the rims.
The only negative really is that it is a bit large to get into some of the tighter recesses of certain rims. If you have rims with many spokes, make sure you measure the openings to determine if this brush will fit.
For reference, the tip of the brush is 6 inches in diameter tapering to 9 inches in diameter at the base.
5. Best for Gutters – Kärcher 20 m Pipe and Guttering Cleaning Kit
Pros
- extra long hose
- Can unblock pipes
- Brass connection for durability
- Anti kink hose
Cons
- Works better with K5 or K7 models
- A little tricky to use
With just one use, you could essentially have this attachment paid for. Leave extortionary rates to wash your gutters or clear your drains behind and take matters into your own hands.
This is the best power washer accessory to clear gutters as it has an ingenious gutter sledge that rides along the gutter, clearing a path with high water pressure. Rather than stand unsteadily on a ladder, let the sledge do the work for you while you stand safely on terra firma.
One thing to note is that for tough build-up in a gutter, you should have high-pressure models like the K5 to K7. If you are looking to use it as a preventive measure regularly to prevent that type of build up, then you could get away with a lower pressure model.
Continuing my love affair with multi-use tools, this serves equally well as a way to clear slow or blocked drains. Again, the cost of having a plumber come to your house is more than what you will spend on this attachment, saving you money even if it is only used once.
Other Kärcher Pressure Washer Accessories
Kärcher Extra Long Angled Spray Lance
I was unsure where to categorize this attachment as it can be used brilliantly for cleaning the undercarriage of your car, the roof or even in narrow spokes of your wheel rims. It is a great Karcher accessory, then.
But, it is also the best pressure washer attachment for cleaning out your house gutters.
The head is angled at 90 degrees and sports a powerful fan of water. The lance is long enough to reach some tough to reach areas making it very versatile.
Let’s just file this attachment under “Multi-Use” and not pigeonhole it in one category so you can make sure you get plenty of use out of it for various applications.
Kärcher WB150 Power Wash Brush
Another in the growing list of multi-use tools by Karcher is the power wash brush.
Use this tool to gently, yet thoroughly, clean your car, boat, caravan, house siding, deck furniture, or the decking itself.
It is good to use on wooden surfaces as well as painted, without doing any damage.
The brush rotates taking on the brunt of the scrubbing action so you don’t have to. Make quick work of your cleaning job.
The head can be angled to 90 degrees to make it even easier to use on uneven surfaces.
Kärcher Splash Guard for Dirt Blaster Lance
If you have used the Karcher Dirt Blaster lance, then you know the power it has to power through some tough debris. You probably also found that it blasts debris all over the place as a result.
This splash guard could be the solution you are looking for to keep your clean up time to a minimum.
Attach this brush to the Dirt Blaster lance and keep the brush on the surface you are cleaning. No need to press it down as the bristles work best when they are fully extended and when pressed leave openings for the water and dirt to escape. Though the bristles aren’t there for scrubbing, they do give you a bit of an abrasive to get you that extra bit of cleaning power if needed.
The triangle shape makes it ideal for getting into tight corners and stairs.
Which Karcher Attachment is Best?
Though this list is far from exhaustive, I think it’s a good primer to get you started with finding the best accessories for Karcher pressure washers.
You may want to add a special lance like an adjustable jet lance, or a Dirt Blaster lance, for when you need some heavy duty cleaning power. Or, you may want a longer hose to give you more of a cleaning radius.
Whatever your cleaning needs, chances are that Karcher has a tool specific to the job.
