If you're looking for the best foam cannon for pressure washers, this is it.

Why This Foam Cannon Produces Thicker Foam

Not all foam cannons are built the same.

The Ethos Pro V2 uses an upgraded air-injection system that increases foam density by up to 50% compared to standard foam cannons. That means:

Thicker foam
Longer dwell time
Less soap usage
Better dirt encapsulation
Reduced swirl risk during contact washing

Pair it with a high-lubricity shampoo like Ethos Pure Car Soap or Ceramic Shampoo and you’ll get true snow-foam coverage.

What Is a Foam Cannon?

A foam cannon is a pressure washer attachment that mixes water, air, and car shampoo to create thick foam that blankets your vehicle before washing.

Unlike a bucket wash alone, foam pre-soaks your vehicle to loosen dirt and road grime before contact. This helps reduce friction and lowers the risk of scratching your paint.

Foam cannons are one of the safest and most effective ways to wash a vehicle properly.

Foam Cannon vs Foam Gun – What’s the Difference?

Many people confuse foam cannons and foam guns.

Foam Cannon

Connects to a pressure washer
Produces thick, shaving-cream-style foam
Adjustable spray pattern
Best for professional results

Foam Gun

Connects to a garden hose
Produces lighter foam
Less dwell time
Lower cleaning power

If you want maximum foam thickness and better cleaning performance, a foam cannon is the superior option.

The Ethos Foam Cannon Pro V2 is compatible with pressure washers operating between:

1000–4000 PSI
