Foam Cannons
Our pick
Adam's Premium Foam Cannon 2.0
Choose Adam’s Premium Foam Cannon 2.0 for its adjustable soap mix and wide opening for pouring soap. Match its 1/4-inch quick-disconnect connection and published pressure and flow requirements to your washer before buying.1
Why this one
- The mixture valve lets you adjust dilution, and the wide-mouth canister makes it easier to pour from a gallon container. It connects through a 1/4-inch quick disconnect.1

Buying advice
- Consider Griot’s Garage THE BOSS BF302 when its included stainless-steel quick-coupler plug matches your pressure washer. Its mixture control also lets you adjust the soap ratio; check its operating requirements before buying.24
- Adam’s lists an operating range of 870 to 3190 psi and 1.3 to 5.3 gpm. Check the pressure washer’s operating specifications and the cannon instructions, rather than choosing by a peak-pressure headline alone.1
