So it seems that everyone in every "car washing" video has a foam cannon. Everyone but me.

Now, I wash my cars weekly, so there's a lot of washing going on around here, and they're usually not too dirty when I do wash them; it's usually spurred by a day of rain or this time of year, a crapload of pollen.

I don't intrinsically understand the benefit of these foaming soap things, other than that it looks really cool when the entire car is covered... but I can't wash the entire car before some of the soap starts to dry. So I usually do it in sections, especially in the summer when it's warm/hot and often there's some direct sun as well. I use very soapy water, and a microfiber spongey thing.

Can someone educate me, or is it just another one of those gimmicks?
