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…..

I had seen online cars being cleaned with snow foam and that it was great for lifting the dirt. We have a Karcher K2 and got this to use on our car. It was very easy to use. The bottle didn't seem to screw on fully but never got any leakages throughout use. Got a great foam coverage (we used turtle wax snow foam). The car came up sparkling. Will definitely use again.

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

Update: 2019 June. The seller gave a refund straight away. No questions asked. They exceeded normal customer service and actually gave me a second unit to try, they were confident it would work as described. The second unit worked as expected. So i would recommend them 100% from my experience so far. Original Review: I have 3 faults, the bottle when fitted sits at the bottom. It was always loose and even with more tape it would still work loose as the weight of a full bottle was too heavy when sat down and not in use and the karcher adapter did not work right. I could not get an adjustment that gave good foam. so I have had to return it. It was not low cost and thought it would have worked better.

Great. I had a previous lance that stopped working. I saw this was on offer for about a third of my previous so bought one. It's equally as good as the old one and seems better made. Sprays a good blanket of foam. Very impressed fits my Karcher K5

Small but does the job.

Ich habe die Schaumkanone bisher zweimal mit meinem Auto und einem Kärcher K4 benutzt. Die Montage und die Einstellung eines guten Mischungsverhältnisses fällt mit den üblichen Youtubevideos zB von Detailingschool leicht. Für meinen Schaum (Valet Pro advanced neutral snow foam) habe ich 100ml Schaum eingefüllt, mit Wasser aufgefüllt und drehe die Wasserregulierung oben fast ganz zu. So entsteht ein schöner Schaum der mehrere Minuten stabil bleibt. Wir sind zufrieden, meine Kinder wollen beim Waschen immer den Teil mit dem Schaum übernehmen :)

Ho acquistato questa lancia per utilizzare la mia idropulitrice come foam gun e devo dire che mi sto trovando molto bene. È comoda da utilizzare e permette di distribuire bene la schiuma sulla macchina, rendendo il lavaggio molto più piacevole e pratico. Con il giusto detergente si riesce a ottenere anche il classico effetto schiuma da autolavaggio professionale, che fa sicuramente la sua bella figura. Per chi ama lavarsi la macchina in autonomia e vuole aggiungere un po’ di effetto “wow” al normale lavaggio, è un accessorio che consiglio.

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

Genial para poder limpiar todo tipo de superficies, se adapta perfectamente

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.
