Foam gun with single nozzle

While the “alternating nozzle” setup is popular for detailers who want maximum control, a single-nozzle foam gun (often referred to as a “Standard” or “Integrated” foam gun) is the preferred choice for most homeowners due to its simplicity and ease of use.

A single-nozzle foam gun is usually a 2-in-1 tool that connects directly to a standard garden hose rather than a pressure washer.
