To determine whether a foam cannon is right for you, it’s important to get a sense of the benefits it provides.
Usually, your only option for removing heavy dirt buildup on your car is firm scouring. This can be effective, but it typically involves a fair amount of scrubbing, which can be physically taxing. Also, with heavy scrubbing, there’s a risk that you’ll damage the car’s paint.
A foam cannon, on the other hand, uses pressure and foam to loosen dirt. This minimizes the need for scrubbing, which means less physical work for you. And since you’re scrubbing the car less than you otherwise would, there’s less risk of paint damage.
If you like the idea of washing your car with minimal scrubbing and less risk of creating swirls on the paint, you’ll likely regard a foam cannon as essential equipment.
