How to Choose the Best Foam Cannon

A foam cannon is a special nozzle that you attach to a pressure washer or a hose to spray foam soap all over an area. The most common application is in car washing, where you can get the foam into every nook and cranny and it cleans the outside to a perfect, glittering shine. We’ve put together this foam cannon buying guide to help you choose the right one for you, but let’s look at some specifications first.

Best Foam Cannons

Capacity: Most foam cannons come with a tank that you attach with the soap in it. This refers to the size of this reservoir and how much soap you can carry around at one time before you refill.

Best Foam Cannons

Pressure: This is how much pressure the nozzle can handle at its peak. Obviously, performance here will need to be measured with the power washer you’re going to be using as well, so keep that in mind.

How to Choose the Best Foam Cannon

Connector Size: You want a cannon that’s going to fit on your pressure washer or water hose, so make sure that you’re getting one with the right size connector for the equipment you already have to avoid unnecessary costs.

Best Foam Cannons

Pieces: What comes with the foam cannon? This includes the nozzle and the bottle, which is usually all that comes with one. The pressure washer is sold separately, and for most cannons, you definitely will need one.

Best Foam Cannons

Adjustable: How many spray modes are there? Some come with such a huge variety of different spray adjustments, which is useful for a wider variety of applications. There are different settings for spreading car wash foam and other types.

Multi-Use: This refers to what you can use it for. Obviously, the most common use is for car washes, but outside of that, there are a whole plethora of uses that you can put these things too. Multi-use is a great buy!
