What is the Difference Between a Foam Gun And a Foam Cannon?

At first glance, there is no difference. Both devices produce foam and look similar. However, if you take a closer look at the two units, you quickly see that the new wave of foam cannons out on the market today are not your grandfather’s foam gun. What makes them different? How do they work?

Making a distinction between a foam gun and a foam cannon is as difficult as drawing the line between a standard pressure washer and a high-pressure cleaner. Both are designed to produce foams of different size, density, and thickness. The difference between them mainly lies in the way they generate those foams.

The difference in foam characteristics produced by a foam gun and a foam cannon

A foam gun produces thick shampoo-like suds that cling to one another so densely, it fills even porous cracks/grooves within washable surfaces providing lubrication for easier cleaning by mechanical means. This minimizes the use of soaps or detergents necessary for washing your car, thus saving resources and money spent on soap or water volume used. Such dense concentrations of rich lather produced by foam guns are also good at trapping dirt and grime in it, making it easier for consumers to wipe off.

A foam cannon generates a mixture of air and water that is thinner and not as densely concentrated as a foam blaster. This allows the product used in washing your car to penetrate deeper into the surface being treated resulting in greater cleaning efficiency.

The difference in preparation time required for a foam gun and a foam cannon

The preparation of both foam guns and foam cannons before use is a snap. Simply add the recommended amount of soap or detergent into the appropriate dispenser in either device, then turn it on and pull the trigger to gather a lather that clings tightly to itself. The only difference would be that with a foam cannon, there is no need for you to wait for suds to rise up from the bottom because when it’s turned on, it will run water through its assembly at full blast thus releasing a mixture of air and water bubbles from its nozzle tip instead of thick shampoo-like suds from yours. This might seem like an insignificant detail but when you consider how long it takes to prepare, this could mean the difference between being able to wash your car before or after work.

Is one better than the other?

As with everything else in life, there is no such thing as “the best” solution. It all depends on your specific needs and preferences. For example: if you want to use more soap or detergents for washing your car, then it would be better for you to buy a standard pressure washer (foam gun) – simply because it uses less soap/liquids than a high-pressure cleaner. On the other hand, if you want to use less soap or detergents for washing your car, then buying a high-pressure cleaner (foam cannon) is definitely the way to go.
