Share
So, you're looking to up your cleaning game and looking for a Foam Gun or a Foam Cannon. But what's the difference between the two? Let's compare the two below.
3 Key Differences Between Cleaning Cannons and Guns

At Clean Offroad, we want to help you understand the differences between these two cleaning products. Here's a simple comparison to make it easier for everyone!
1. Power Source
A Foam Cannon connects to a pressure washer, which uses powerful water pressure to create a rich, thick foam that sticks to surfaces. This makes it perfect for tough cleaning jobs and removing stubborn dirt and grime.
In contrast, a Foam Gun is attached to your garden hose. It's great for quick clean-ups and lighter cleaning tasks around your home or yard. So the first step in deciding is, do you have a pressure washer? And are you likely to pull it out to clean your 4wd?
2. Foam Quality and Thickness

A Foam Gun that connects to your garden hose creates a light, airy foam that's great for a quick and convenient clean, without the hassle of getting the pressure washe rout. However, a Foam Cannon that attaches to your pressure washer, will produces a thicker foam that sticks to surfaces longer, making it easier to clean effectively.
3. Cleaning Intensity
A Foam Gun works well for a smaller cleaning task. Maybe it is a general wash and the vehicle isn't too dirty. Whereas a Foam Cannon is better suited for tougher cleaning tasks, when your vehcile is particulary dirty after a camping trip or beach adventure. Using the extra power of the pressure washer, the thicker foam will help remove dirt, grime, and other stubborn messes.
