I would like to start to use a foam cannon to clean the Porsche. That said, which electric pressure washer are people using and recommended? Also which foam cannon is recommended?

I think the top foam cannon is MTM Hydro though most vendors I've seen seem to buy it and put their own name on it before reselling...usually at a higher cost. I can't comment on an electric power washer as mine is gas, but I will advise you to watch the pressure and flow rate. Mine is too high and no matter how I adjust the cannon I always get too much water in the mix and something short of foam coming out of the cannon. I think it's at 3100psi and 3gpm, so aim for something less.

What is the ideal range for the GPM? What is the PSI ideal range? Both for a foam cannon to work properly.

If you check out the chart on this page you can see the ranges... https://www.esotericcarcare.com/mtm-...am-cannon-kit/

And a video that goes over the MTM lineup...

Do you sell just the nozzle orifices? I believe my foam cannon came with the standard 3.5mm orifice and I later bought a 3.0mm hoping to improve performance. According to the chart that should work, but it doesn't. I'd like to source 2.5mm and 4.0mm orifices to see if going larger or smaller makes any difference.


OP, when you do pick a pressure washer I definitely recommend the kit Esoteric linked here. I upgraded my washer to the MTM SG28 gun / handle. No safety button / trigger to push down every time you want to spray. The safety lock folds up and stays up out of the way. Just squeeze and spray. It's amazing how one one little ergonomic change improves the whole car washing event.

I still have my gas washer, but decided to buy a Kranzle electric PW after trying some cheaper electric ones. The Kranzle is a TANK! I also bought the Mosmatic setup from the Obsessed Garage Store (I picked it up since I live about an hour away). I have the original MTM foam cannon. I have quick connects so it’s easy to setup and put away once done.
I’m very satisfied with the current setup.

If you can afford the Kranzle I’d go for it.

Just to clarify, there are two different types of nozzles:

1. There are nozzles that spray water from the spray gun/extension lance. These control the flow of water as it leaves the spray gun. Check out this link for those nozzles.
2. There is a nozzle on the inlet side of the foam cannon that controls the flow of water from the pressure washer. A less powerful pressure washer (less than 2.0 gallons per minute) will need a smaller orifice. See this link for a small orifice for foam cannons. For more powerful pressure washers, the standard nozzle in MTM Hydro Foam Cannons will be sufficient.
