How to match a foam cannon to the pressure washer and soap
Foam-cannon performance depends on the pressure washer, soap concentration and cannon orifice working together.
Compact electric washers often need a smaller orifice to create dense foam, while higher-flow machines may perform better with the standard opening.
Prioritize compatibility and real use
Adjustable top controls change detergent draw, while the front nozzle controls spray width and direction.
Evaluate installation and operation
Foam dwell time helps loosen road film, but soap should not be allowed to dry on the vehicle.
Plan for maintenance and long-term support
Flush the cannon with clean water after use to prevent dried detergent from clogging the filter, tube or orifice.

Foam Cannons FAQ
Will any foam cannon work with any pressure washer?
Not always. Fittings, pressure, flow and orifice size must be compatible.
Does thicker foam clean better?
Not necessarily. Coverage, dwell time, chemistry and safe contact washing matter more than thickness alone.
What soap should I use?
Use a vehicle-safe soap formulated for foam cannons and follow its dilution instructions.
Why is my foam watery?
The washer may have low flow, the orifice may be too large, the soap may be too diluted or the filter may be clogged.
How should a foam cannon be cleaned?
Run clean water through it and rinse the bottle, pickup tube and nozzle.
