Buyer questions

Q: Which pressure washers is this accessory compatible with?
This device is suitable for Karcher K-series pressure washers — models K2, K3, K4, K5, and K7. It works with any high-pressure washers, small or large, as long as the pressure is within the specified range.

Question: How do I properly prepare the foam mixture?
You need to pour shampoo or detergent into the bottle, add warm (not hot) water in the correct proportions, then shake it to dissolve the shampoo properly and create more foam.

Question: Why is the bottle blue in the pictures, if the description says it is white?
The bottle itself is white, but it appears blue in the pictures because it contains detergent inside, which gives it that color through the transparent wall.
