Qooltek Adjustable Foam Cannon 1 Liter Bottle Snow Lance Foam Dispensing Nozzle Soap For Karcher K Series K2 K3 K4 K5 K6 K7 Pressure Washer

This fits my basic Karcher perfectly. I got a bit confused with the plus and minus settings on my initial go and emptied the snow foam after only doing one side off a the car. The plus and minus are referring to the jet washer not the contents, so plus means less snow foam. Overall a nice product with an OEM feel about it.

Excellent foam cannon and great performance ⭐⭐⭐⭐⭐ The Qooltek Adjustable Foam Cannon (1 L) works perfectly with my Karcher pressure washer and makes car washing so much easier. It produces thick, rich snow foam that clings to the paintwork really well, helping lift dirt before you even touch the sponge. The adjustable nozzle and foam output give you good control, and the bottle feels sturdy and well‑made. Easy to attach and clean, and saves loads of time on prep and rinsing. Definitely a great addition to any car care setup — very happy with it!

Bought this a few weeks ago as an additional snow foam applicator, rather than use the same one for both snow foam pre-wash and shampoo foam. Used for the first time today to apply foam shampoo after using my original for the snow foam. I got absolutely zero foam from this applicator, regardless of adjustment, just sprayed out water (and yes, the inner tube was in place correctly and submerged in the shampoo/water mix). The adjustment knob only turned one full turn from min to max, compared to my perfectly working original which turns about 3 times between the extremes. To confirm that it wasn't working correctly, I tried the new spray head with my original applicator & foam mix and still no foam at all. Conversely, the older head on the new bottle with the shampoo mix worked perfectly, so definitely nothing to do with my mix ratio. It may be that I've just been unlucky & got a dodgy item, but have requested a refund. I'll probably go & spend more and get another Autobrite one as per my original. **UPDATE** After having had a refund for this item, the seller contacted me to offer, firstly, their apologies, and secondly to offer me a replacement free of charge, they were sure I'd been unfortunate & received a faulty item. I'm prepared to give anyone a second chance, so I accepted, on the understanding that, if it failed again, then my review would be updated accordingly. Likewise, the same would happen if the replacement item was OK. Anyway, having finally tried the new one, I can report that it works fine, but isn't perfect. I get e decent level of foam, but not as thick or "sticky" as I get with my current foam cannon. However, it's suitable for the initial pre-wash, maybe this one, compared to my old one, requires a different ratio of product-to-water, experimentation will make that clearer, but, as i said, it'll do what it needs to. I'm amending my initial rating from 1-star to four, not specifically for the operation of the cannon, but more for the Customer service from the supplier, despite the repeated e-mails asking if I'd tried the new item yet!

The Qooltek Adjustable Foam Cannon works perfectly with my Karcher K7 jetwash to create thick, consistent snow foam. Setup is straightforward, and the adjustable nozzle allows precise control over the foam density. Build quality is excellent - the metal components feel solid and durable. It handles repeated use without leaks or issues, and the foam coverage is impressive for both cars and larger surfaces (I’ve used it on my caravan too) At this point, I haven’t noticed any downsides and I’ve been using it for a few months now, it’s well-made, efficient, and doesn’t feel heavy when in use.

good product. Makes a difference to the body work.,

I bought this item as a replacement for my Karcher K2, my original snow foam gun was directly from Karcher and broke within 3 months. This one is far superior for less cost. It's easy to use, the scale on the side of the bottle makes it easy to get the ratio's perfect and it gave me the best clean I've had yet Adjusting the jet and power of the foam was simple and it was perfectly compatible with my K2 and was a lot easier to fit compared to the actual Karcher ones. This is the best foam gun I've bought so far

Can be difficult to connect to lance. Not a 100% fit. Also the bottle broke afer a few months of use, so its no longer useable. I wonder if bottle can be replaced separately???

I bought the Qooltek Foam Cannon to use with my Ava P50 Easy pressure washer. The fit on the gun is secure and there is no leakage from the connection point. Unfortunately, the product does not fit onto the mounting bracket as this is specifically designed for the Ava Foam Cannon. The product design is good and build quality seems excellent. Foam coverage is superb, half a bottle covers a large car quite easily.

Lo uso para lavar autos

Very good

Was für eine Wirkung! Ein riesiger Unterschied zu meinen bisherigen Erfahrungen mit Schaumkanonen. Diese Schaumkanone ist wirklich gut. Direkt an den Hochdruckreiniger aus dem Schwabenland angeschlossen und mit Autoreinigungsschaum befüllt. Beim ersten Einsatz war ich direkt total begeistert. Man kann die Spraymenge und die breite des Strahles einstellen. Mit einer Füllung konnte ich 2 Autos komplett einschäumen. Zwischenzeitlich nutze ich das Gerät auch für Wohnwagen und Fahrräder. Zusätzlich lässt sich das Teil leicht reinigen und schnell wieder einsatzbereit machen. Fazit: es wird keine Kaufreue geben - also kaufen!

Ottimo funzionale

it worked once and then it broke…
