Stone Banks Snow Foam Gun for Karcher K Series K2 K3 K4 K5 Pressure Washer

I paired this up with a adapter for my old Qualcast pressure washer and it's perfect. Nice controllable thick foam.

Excellent quality and attaches directly to my Karcher K7. When three quarters full there is sufficient to use liberally on two large estate cars.

I don’t often leave reviews but after years of several Karcher snow foam bottles this has produced the foam you see in all the advertisements videos. I was always convinced it was AI but this bottle delivers. Should have bought this from the start, thick blanket of foam. The best part, uses less than 1/4 of the snow foam the Karcher uses! Pays itself off…..

Only 4stars as I’ve not been able to use it yet, but it fits my Karcher 1 perfectly. Looks to be of good quality.

This is the first snow foam lance that’s actually worked for me. My Kärcher never came with one (or the original broke years ago, can’t remember), so I’ve been missing out. Connected this in seconds – literally clicks on, no leaks, no adapters. Paired with Carplan Demon Snow it throws ridiculously thick, clingy foam that blankets the car and hangs around long enough to do the job. First use I got carried away and the entire driveway disappeared under foam while I was testing the adjustment, so yeah… it works. 1 L bottle is a handy size, the nozzle adjusts easily, and the whole thing feels properly solid – already dropped it once and no damage. For the price it’s an absolute game-changer if, like me, you’ve never had a decent lance before. If you’ve got a K2–K7 and want proper pre-wash foam without drama, just buy it. Delighted.

If you own a Karcher K Series pressure washer (K2 to K7) and are tired of the weak, watery soap dispersion from the standard detergent suction, the Stone Banks Snow Foam Lance is an essential upgrade. I’ve been using this for several months on my K5, and the difference in pre-wash efficiency is night and day. Build Quality & Fittings The first thing you’ll notice is the weight. Unlike the cheap plastic foamers often bundled with entry-level machines, this unit features a heavy-duty brass core. The Connector: The bayonet fitting is specifically designed for the Karcher K Series. It clicks in securely with no leaking—a common issue with cheaper universal adapters. The Bottle: The 1-liter bottle is made of thick, high-density plastic.. It has a wide base, which means it doesn't tip over when you set it on the ground—a small but very appreciated design choice. Performance & Adjustability The foam quality is where this lance shines. It produces that thick, "shaving cream" style foam that clings to the vertical surfaces of the car, dwelling long enough to break down road grime and salt before you ever touch the paint with a mitt. Top Knob (Detergent Mix): Allows you to control the thickness of the foam. You can dial it back to save product or crank it up for a full "snow" effect. Front Nozzle (Spray Pattern): You can adjust the fan width from a narrow jet to a wide 60° spray. This makes it incredibly fast to cover a large SUV or a small hatchback. Ease of Use One of the best features is the transparent bottle with measurement markings. It makes it easy to get your dilution ratios exactly right without having to use a separate measuring jug. Because the internal components are brass and stainless steel, it doesn’t clog easily, provided you run some clean water through it after use. Pros: Exceptional Foam: Produces thick, clinging foam that rivals snow foamers three times the price. Durable Materials: Solid brass construction that feels built to last. Perfect Fit: Seamless compatibility with Karcher K2, K3, K4, K5, and K7 models. Cons: Weight: When the 1L bottle is full, it adds some significant weight to the Karcher trigger gun, which might be tiring for some during long sessions. Final Verdict The Stone Banks Snow Foam Lance is a "no-brainer" for any detailing enthusiast. It transforms a standard Karcher into a professional-grade washing setup. If you want to minimize swirl marks by ensuring a proper touchless pre-wash, this is arguably the best investment you can make for under £30

Bought to use with my KARCHER. It’s a nice bit of kit however 2 things I don’t like. First the metal screw on the top of the connector is threading the plastic bottle already. Can only see it lasting a few more washes before the top won’t screw back on. Also the twisting end of the connector is very loose, meaning you have to constantly adjust the flow of foam. It’s ok for the price but feels cheap.

Attaches and detaches from karcher k7 easily. No drips. Does the job expected of it.

Convient parfaitement pour le karcher k7, aussitôt reçu aussitôt utilisé, rien à redire. Pas de photo d’illustration mais clairement un bon rapport qualité prix

Ich habe mir die Düse für meinen Kärcher K2 gekauft um mein Auto zu waschen. In Kombination mit SnowFoam erhält man ein super gutes Ergebnis. Schöner dicker Schaum in einem dünnen Strahl oder einem breiten Fächer. Die Messingteile sind hochwertig und der Plastikbehälter stabil

WOW. Dit is vele malen beter dan de originele van KArcher? Zelfs op de TLA werkt dat prima.

Karcher k5 ile denedim, birebir uyumlu. Hiçbir yerinden sızdırma yapmadı. Ürünü Divortex Alpha Foam Ph Nötr şampuan ile kullandım ve çok başarılı. Yıkamacılardan farksız köpüğü. Tereddüt etmeden alınabilir.

Funciona muy bien !!!
