Undoubtedly, between these two, the foam gun is the winner here. It is much cheaper than foam cannon.

Pressure Needed to Clean

Normally, a foam gun uses the standard pressure of a garden hose for cleaning. But, a foam cannon needs pressure wash to provide a high-pressure water flow.

Sometimes, due to insufficient pressure, foam cannons will only work when it is flipped upside down. In this case, you have to increase the pressure of your pressure washer to use it in a normal way. But, a few foam cannons are designed to work upside down.


It is an important factor in cleaning. Proper cleaning of the whole surface along with the hard-to-reach areas is desirable.

It is easier to access hard-to-reach areas by using a foam gun. A foam gun provides more precise control and comfort than a foam cannon.

Cleaning Efficiency

The Foam cannons use pressurized water. This water pressure helps to break down the dirt from the car’s surface. So the cleaning achieved will be way better than that of a foam gun.

For getting a better cleaning effect hand wash is done after using foam cannon. First, you have to use foam cannon to clean the surface as much as possible. Much dirt might still be left. So, you better wash the car with your hand to take care of that dirt.

Amount of Soap Used

Foam guns use less amount of soap for cleaning. Inversely, a foam cannon requires a large amount of soap to create excessive foam output. But for getting a thick foam layer by using a foam gun, you have to use a more tremendous amount of soap than is normally needed.

However, while wondering if can you use any soap in a foam cannon, check out everything that you need to know.


In a foam gun, the spray will be thinner and roll down from the surface. Because the water soap mixture is a dilute solution and water doesn’t have much pressure. Thus, it is suitable for smaller surface cleaning.

On the contrary, foam cannons will have a thicker layer of foam. Besides, that will also stay for a longer period on the surface which can cover a larger area more quickly.

Prevention of Swirl Marks While Cleaning

More aggressive foam will produce great lubrication. As foam cannons use pressurized water, more aggressive foam generation occurs than any foam gun.

The risk of swirl marks is disproportionate to the lubrication. So, foam cannons will provide a safer cleaning than foam guns. There is a high risk of getting scratches or swirl marks on the car’s surface if you use a foam gun.
