After purchasing this product without expecting anything extraordinary due to the comments I read that it doesn't do anything, etc., I have to say that anyone who has a Karcher pressure washer in combination with the active foam of Karcher, the RM615, should get it blindly. Today, I washed a white car for the first time with dirt from the exhaust fumes due to working in an industrial area, and the results were better than the car wash I used to go to. It cleaned about 80% of the dirt without even using a sponge on top of the foam. The foam covers the entire car to the point where you can't distinguish the color, thanks to the quality of the foam it spreads. Oh, and something else I read that it requires a powerful pressure washer, etc., I use the K2, which is relatively small in the second category of Karcher

I see an attachment without a container and it does not come with anything else because it simply works with the existing cleaning containers you already have, that's why if you don't have a container, you prefer the complete set. The yellow button on the side makes a difference. On 23/11, personally, I got the attachment with the container, you open the valve all the way and the liquid sticks everywhere, all white, liquid for stone.

The nozzle came without a container and without a cleaning liquid. Also, for older Karcher washing machines before 2010, the "Karcher Adapter M 2.643-950.0" is required because otherwise it does not lock onto the gun. On the positive side, the one-liter containers with Karcher's cleaning agents and foams easily and quickly fit in and out by pressing the yellow button on the base of the device.
