High Pressure Soap Foamer | Snow Foam Lance for Karcher K2-K7 Pressure Washers

Get a thick, professional-grade foam coating on your car with this high-pressure soap foamer. Designed to be compatible with Karcher K2 to K7 series pressure washers, this foam lance transforms your wash routine by creating a dense snow foam that clings to surfaces, lifts dirt, and reduces the risk of scratches. It is a reliable tool for anyone looking to achieve a deeper, contact-less pre-wash at home.

This foam generator is built with a solid brass body and metal components for long-lasting performance. It features an adjustable foam consumption dial and a variable spray pattern that lets you switch from a precise pencil jet to a wide 60-degree fan. This level of control helps you apply soap exactly where you need it, making your car washing more efficient and effective.

The package includes a 1-liter bottle with clear volume markings, so you can mix your soap and water in the right proportions every time. An extra brass nozzle is also included for pressure washers operating in the 100 to 120 bar range. Whether you are a weekend car enthusiast or a professional detailer, this foam lance is built to deliver consistent, thick foam with every use.

This product is a compatible accessory, not an original Karcher part. It is designed to fit Karcher K2, K3, K4, K5, K6, and K7 models. Please check your adapter size before purchase. If you are unsure, contact us with a photo of your gun and lance, and we will help you select the correct adapter.

Usage Scenario

Mark spends his Saturday mornings washing his SUV. He used to scrub dirt directly onto the paint, which left fine scratches. After attaching this foam lance to his Karcher K5, he now sprays a thick layer of snow foam over the entire car. The foam clings to the panels and slowly drips down, loosening road grime and bug residue. After letting it sit for a few minutes, he simply rinses it off. The pre-wash does most of the dirty work, so his contact wash is much safer and faster.

Micro Comparison

Standard spray nozzles on a pressure washer apply a thin, watery soap layer that runs off quickly. This foam lance mixes air and water with the soap to create a thick, creamy foam that stays on the surface longer. The longer dwell time allows the soap to break down dirt before any scrubbing begins, which helps protect your car's paint finish.
