I am in the same boat as these guys.
I have seen the videos and pics of ppl using it. Does the soap really clean that well without scrubbing? Does it work with a regular hose pressure or only high pressure? Do you turn the pressure down on their machines to wash a vehicle? Id hate to hit my car with 3000+psi.
I have both. At the house I don't have a pressure washer just the garden hose type foam Cannon. It does a DECENT job. But one of those deals where if you're washing, say an accord. It will give you enough foam and lather to (hand) wash the top and windows, then rinse, then do the trunk and rear, rinse... Etc whereas the one I have at the barndo with the pressure washer, it makes SUCH thick and fancy foam due to pressure that you can spray an entire suburban, and it stay completely engulfed in foam long enough to (hand) wash the whole suburban before rinsing.
I WILL say the pressure washer foam Cannon does get an amazing amount of nasty off the Jeep after a trip, making for much less hand washing
Either way you do NOT want to use a foam Cannon in direct sunlight just like regular car washing. So it doesn't dry out on you
