Snow Foam Cannon for Karcher K2-K7 Compatible, 1L Bottle

Great piece of kit fits my k4 and does a perfect job. Great build quality nice weight the bottle seals and doesn’t leak. Adjustable spray works really well and covers perfectly. Can’t really speak about cleaning as that depends on the foam you use. It does make a beautiful foam that covers well only gripe and maybe me mine leaks a small amount from the quick connect but that doesn’t detract for me.

I have been using the original High Pressure Washer Snow Foam Gun and thought it was OK until I saw my nephew using his AstroAI Snow Foam Gun and the difference was amazing so I had to get one. This thing is AWESOME. It has adjustable Foam strength (more or less water) and Nozzle for the perfect application spray jet. It also 'self alights' upright on your Lance so that there is not interruptions in Foam application no matter how use aim the gun. The additional Karcher Adapter makes it a breeze to fit and the Build Quality is exceptional. If you are in the market for a new Snow Foam Gun, look no further. This performs as good as any gun I've seen. Excellent product at an affordable price and one that will last for a good while...

This was a replacement for another AstroAI foam fun. I ended up buying the second one after my first broke when I dropped it, and this one feels much more solid. The build quality seems better and it gives me more confidence it will last. Performance is the same as ever, thick, even foam, easy to adjust, and the wide-neck bottle makes filling hassle-free. Works exactly as you’d hope for a snow foam gun. Overall, very happy with this one and glad I replaced the first.

I bought this to replace my Mcguires foam canon which has mysteriously stopped producing foam. No amount of cleaning or adjusting could get back the the luscious foam I used to get so I bought this one to replace. So when I tried it I got mixed feelings as it foams OK but not the thick shaving foam you get with the more expensive pro foam canons. Maybe you can with a better more powerful pressure washer but I heard that the internal nozzle could be changed out for a 1.1mm and that would do the trick. So for about £5 I got a couple and dead easy to replace as just the quick connector to remove. Anyway, I tried it using the same solution which I still had plenty left in the bottle and the difference is ridiculous! Really thick proper foam and even better that previously got from my Mcguires! I am really glad I didn't fork out for a really expensive pro foam gun. This simple mod has worked really well and difficult to imagine it could be any better. My pressure washer is a budget Titan washer from Screwfix and now my set up produces foam that looks like the pro's!

I have used an Autobrite Direct snow foam cannon for years before purchasing this unit. I really like the tapered bottle which allows the cannon to stand upright even when full. The large fill hole means you don't spill any product when filling and do not need to use a funnel. The unit comes pre-fitted with a cheap brass 1.4mm nozzle tip. I imagine a lot of these 'budget' snow foam lances around this price point have this. I purchased a stainless steel 1.1mm nozzle tip and fitted that (my previous cannon had the same fitted). Picture supplied of new nozzle fitted. Simply, take off the quick connect (16mm spanner) and unscrew the nozzle (large flathead screwdriver) to replace with the upgraded one The unit, after modification now outperforms cannons twice / three times the price. The foam produced is like shaving foam and clings to the car for a long time (Pro-Kleen snow foam, mixed in the correct ratio as per the instructions, Karcher K3 jetwash) Spend the extra £3 on the 1.1mm nozzle modification (You get three in a pack so can keep the rest for future cannons if you like) and you have one heck of a cannon for the price

Used this a good few times now and still going strong. Is a budget option though and you can notice the difference if you’re coming from a more expensive quality product. The pipe going into the bottle is short and bent I’ve tried straightening it but annoyingly it doesn’t work but I normally have product left in the bottle so it still gets to suck it up. The adjustment nozzle isn’t the best all or nothing but it does the job.

This product is not good at all, we used it once and it blocked up and no snowfoam is coming out. Overpriced and a waste of money.

Does the job, but goes uses up the liquid very quickly

Muy satisfecho con este cañón de espuma, llevo más de un año usándolo y es sorprendente la calidad de espuma. Antes de comprar vi una reseña del producto y me decidí a comprarlo, fácil de usar, fácil de limpiarlo, es muy resistente y la adaptación a mi hidrolavadora fue muy fácil. Lo recomiendo ampliamente, más que compartir la foto del producto, comparto el resultado de como quedó mi auto después de haber utilizado un champo de ph neutro en el cañón de espuma.

The AstroAI foam cannon performed very well, especially considering the price range. I paired it with the AstroAI pressure wash gun, which is excellent as well. I highly recommend using the two together. The build quality of both seem strong and not cheap like other brands on the market. The only minor drawback is the turning knob that adjusts the spray orientation on the foam cannon. It feels quite stiff, but it may loosen up over time with use. I used a 1:4 soap to water ratio (200ml of soap mixed with 800ml of hot water) with Chemical Guys Watermelon Snow Foam. The foam was thick and covered my car nicely. In a previous attempt, I used a 1:12 ratio, which was too watery. Increasing the soap concentration definitely produces much more foam. The pressure washer I used is electric with 2030 psi and 1.2gpm.

Right out of the gate I'll say that cost and mouth opening was a factor in my purchase. I just don't want to spend a lot of money for this type of product. That being said, I don't have a reference point to say a $50 dollar unit is better or not. I can't tell you if this performs as well as those with the same soap solution ratio. What I can share is that this has been a solid performing unit. With a normal 5oz to 30oz ration, and the right type of soap, it foams up and suds very well. I've been experimenting with soap of a reasonable cost and some perform better than others. I have not had issues where I felt it was not living up to the bill of a foam cannon. Built quality appears to be excellent. The larger opening makes it easy to apply soap and water. I don't tweak the nozzle, leaving it on full foam. For reference, I have this attached to Ryobi electric pressure washer so can't comment if a higher water volume or pressure impacts performance. What I can say is that it has been a great working unit for my set up. The bottle (30 oz of soap solution) will typically last a car (SUV, large car). It is quick and easy to refill if doing multiple cars in a wash session. The bottom line...I like this unit and would buy it again or recommend it to you.

Genera bastante espuma, no le pide nada a marcas mas costosas. Use gold class de meguiars y el resultado fue una espuma bastante abundante y espesa. La use con una koblenz de 2600 psi. Me encanto el resultado, a demas que los materiales son resistentes.

The AstroAI Foam Cannon has seriously leveled up my car washing routine. Paired with a decent pressure washer, this thing produces rich, thick foam that clings to the surface — perfect for loosening dirt without having to scrub aggressively. The wide neck design is a smart touch — it’s way easier to fill and clean compared to narrower bottles. The 1L capacity is more than enough for a full vehicle wash, and the adjustable foam control and spray pattern work exactly as expected. I was able to dial in the perfect balance between foam thickness and water usage. Build quality feels durable and heavy-duty. The connectors fit snugly and don’t leak, and the whole unit feels like it can handle regular use without any issues. If you're looking for a reliable foam cannon that delivers great results without breaking the bank, this is a solid choice. Makes car washing faster, easier, and a lot more satisfying.
