FUNTECK Foam Cannon Lance Compatible with Karcher K2/K3/K4/K5/K6/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

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

This product did the job well. Purchased it for some time now, easy to use, even my 8 year old uses it without a problem

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.

Great

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.

Just what I needed works well no problem

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!

This foam cannon works perfectly with my Karcher K2 pressure washer—no adapter needed, which is a huge plus. It connects just like any standard Karcher accessory. The bottle is a good size and holds enough water and soap to clean one car without refilling. The only downside is the build quality—it's mostly plastic, so durability might be a concern over time. Also, the knob to adjust the soap amount is a little stiff, which makes fine-tuning a bit tricky. Overall, though, it's a convenient and functional addition to any Karcher setup.

Works well

Produces a good foam with the right soap.

Connected beautifully to my Karcher electric washer. Used Turtle Wax snow foam soap and you would think we just had a blizzard. Thick snowy foam and it barely drew any out of the supply bottle. Very pleased and highly recommend.
