Karcher Foam Cannon

A 700 ml foam cannon/lance designed for Kärcher K‑series pressure washers (models K2–K7), this accessory lets you generate thick, clinging foam that improves cleaning performance by loosening dirt and grime before rinsing. The foam cannon attaches to your pressure washer gun via the Kärcher bayonet/quick‑connect system and features an adjustable nozzle and foam‑mix control, so you can tailor foam output and spray pattern to the job. 

Key Features

• 700 ml foam reservoir: Large enough to cover multiple vehicle washes or outdoor cleanups without frequent refills.  
• Adjustable foam output & spray width: Easily change how much foam is produced and the width of the foam spray for different surfaces.  
• Compatible with Karcher K2–K7: Designed to fit the rectangular bayonet gun connection used on most Karcher consumer pressure washers.  
• Durable build: Made from combinations of plastic, brass hardware and high‑density bottle materials for reliable use.  
• Simple to use: Fill with water and detergent, attach to your pressure washer gun, and spray foam over your vehicle or surface without extra adapters.  

Use Case

Perfect for car enthusiasts or homeowners who want to apply thick, snow‑like foam for pre‑wash cleaning. The 700 ml capacity and adjustable settings give you better control over foam thickness and coverage, making high‑pressure washing faster and more effective on cars, patios, siding and other outdoor surfaces.
