Foam Cannon vs High-Pressure Hose – What’s Actually Needed?
You’ve seen those viral foam cannon videos—but do you really need a pressure washer to get results that good? Not always. Here’s the real answer.
💭 Myth: Foam Cannons Only Work with Pressure Washers
While most foam cannons are designed to hook up to a pressure washer, that’s not the only way to get thick foam. There are two main types of foam cannons:
- Standard Foam Cannons: Attach to a pressure washer for max foam thickness.
- Foam Guns: Attach to a regular garden hose and still produce usable foam.
The biggest difference is the pressure and volume of water (PSI & GPM). Foam guns run off water pressure alone, while true cannons need the extra PSI boost to atomize the soap better.
🧼 How to Get Thick Foam Without a Pressure Washer
If you don’t want to buy a pressure washer, here’s what still works:
- Use a high-quality foam gun that attaches to your garden hose.
- Use a dedicated soap like The Super Soaper designed for maximum foaming action.
- Start with warm water in the reservoir and shake well before use.

🔍 Real-World Testing: Foam Gun vs Foam Cannon
We tested both setups using The Super Soaper in the same ratio:
- Foam Gun (garden hose): Medium foam, great for light duty and quick pre-washes.
- Foam Cannon (pressure washer): Thick shaving cream-style foam that clings and lifts dirt effectively.
If you’re doing maintenance washes or don’t mind a slightly thinner foam, a hose-attached foam gun is perfectly usable. But if you’re chasing that ultra-thick, clingy foam—a pressure washer is the way to go.
🧠 Final Verdict
You don’t need a pressure washer, but it helps. If you’re just starting out or working in a driveway without outlets or setups, a foam gun and The Super Soaper will get the job done.
