Foam Cannon vs Foam Gun: What’s the Difference and Which Should You Use?
If you’re getting serious about car washing, you’ve probably heard about foam cannons and foam guns. While they sound similar, they serve different types of users. This guide breaks down the differences, benefits, and which one might be the better fit for you.
What Is a Foam Cannon?
A foam cannon connects to a pressure washer and sprays thick, shaving-cream-style foam. It uses high-pressure water to agitate and aerate the soap into dense foam that clings to your vehicle.
Pros:
- Thick foam that clings longer for better cleaning
- Ideal for touchless or semi-touchless washes
- Great for coated or sensitive paint finishes
Cons:
- Requires a pressure washer
- More expensive upfront
What Is a Foam Gun?
A foam gun connects to a standard garden hose. It still creates foam, but it’s much lighter and less dense compared to a foam cannon.
Pros:
- Lower cost, no pressure washer needed
- Beginner-friendly
- Easy setup and cleanup
Cons:
- Foam isn’t as thick or effective
- Shorter dwell time on dirty surfaces
Which One Should You Choose?
If you already own a pressure washer and want thick foam for touchless or coated vehicles, a foam cannon is the clear winner. It pairs perfectly with The Super Soaper to break down dirt and road film with minimal contact.
If you're just starting out or want a quick, low-cost upgrade from the two-bucket method, a foam gun is a great way to experience safer washing without investing in a pressure washer.
Pro Tip
No matter which option you choose, your results will depend on your soap. Cheap soaps don’t foam well and can strip protection. For maximum foam and safety, use The Super Soaper.
