Foam Cannon vs Foam Gun – What’s the Difference?
What’s the real difference between a foam cannon and a foam gun—and which one should you use? This post breaks it all down with pros, cons, and product tips.
What Is a Foam Gun?
A foam gun attaches to your garden hose and creates suds directly from the water pressure coming from your tap. It’s great for people who don’t have a pressure washer but still want a pre-foam step before washing their car.
Foam Gun Pros:
- Works with any standard garden hose
- Easy setup and storage
- Lower upfront cost
Foam Gun Cons:
- Produces thinner foam
- Less effective at loosening grime
What Is a Foam Cannon?
A foam cannon connects to a pressure washer and creates thick, shaving cream-style foam. This type of foam clings to your paint longer, helping lift dirt and reduce the chance of scratches during the contact wash.
For best results, pair it with a proper soap like The Super Soaper.
Foam Cannon Pros:
- Produces ultra-thick foam
- Loosens dirt before any contact is made
- Ideal for ceramic-coated vehicles
Foam Cannon Cons:
- Requires a pressure washer
- More expensive overall setup
Which One Should You Use?
It depends on your gear and goals:
- Foam Gun: Great for beginners or those without a pressure washer
- Foam Cannon: Best for serious enthusiasts and pros who want top-tier results
Pro Tip: Regardless of which foaming method you choose, always follow up with a safe contact wash using a towel like the Orange Wash Microfiber Towel.
