Foam Cannon Lance for Karcher K2-K7 Pressure Washer | Adjustable Soap Dispenser for Cleaning Vehicles, Cars, Motorcycles and Bikes, 700 ml

I was a little leery when I ordered this that it was going to leak or give me problems due to it's low cost, but it's ran great with my Karcher pressure washer. I'd give it an A+ on value, build quality, and ease of use. I used Adam's Polishes Mega Foam soap with the foam cannon: https://www.amazon.com/dp/B07SPY1CLW I've found that you probably want to have the dial on the foam cannon set to a lower setting that I would have guessed to get the foamiest bubbles, but it's quick and easy to adjust to knob until you find the setting that works best for you.

Amazing how much foam it produces. Works great and exactly what I needed

Works great.

Crazy how wonderful this works!!! game changer!!!

Great

Simple to use and works effectively! My only gripe is the inner suction tube inside the bottle can get a little finicky and I had to wrestle it to bend the way I wanted and stay put. But other than that it works great and I won’t even dock a star from the review.

Attaches to my pressure washer and works perfectly. It’s super easy to use and feels well made. I can’t really ask for more than that.

After a yay and nay in the Amazon Q&A as to whether or not would work with my old Karcher 330 (1996), it arrived today and sure enough, it works great! Fits perfectly and makes great foam just like I had hoped. I used Meguiar's Gold Class Car Wash concentrate. Not knowing how much or if I should add water to the concentrate, I went ahead and poured-in a few ounces and added about a 8-10oz of water (half full?) and that worked to perfectly foam-up a small sedan. I was never able to find an official Karcher foamer that would fit this old Karcher 330 but I'm all set now!

Bought this foam lance/cannon to clean eaves trough, siding, garage doors etc. I expected some foam and likely a large supply of soap to produce it. Instead, I used a very small amount of dollar store dish soap to wash about 75ft of the house. Eaves/sofit/brick and windows all received a thick coating of dense foam. The density let the foam stick to elevated vertical surfaces easily. After sitting on surface for 5 minutes, I used the standard wand and rinsed away dirt. Exactly as advertised and expected. Could be the cheapest great tool I have bought. Do not hesitate to buy this foamer.

Good Price Work well

This foam gun is an absolute game-changer for car washes at home. It hooks up easily, sprays a thick, satisfying layer of foam, and makes you feel like a pro detailer in your driveway. The adjustable nozzle lets you control the foam density, whether you want a light mist or a full-on whipped cream blast. Pros: Easy to attach and adjust Produces rich, thick foam for better cleaning Saves time and soap compared to bucket washing Makes washing your car weirdly fun Cons: Needs a decent pressure washer to shine Plastic bottle could feel sturdier If you love your car (or just hate scrubbing it), this foam cannon is a no-brainer. Just don’t blame me when your neighbors start asking for a turn!

Works good

Produces a good foam with the right soap.
