Ok... Foam CANNONS, GPM or PSI ? for thicker foam

[sasson]

Hello, I found about 20 Different threads on Autogeek and other forums but NO ONE gives the right answers...
People just Get Confused.

The Question is, When using a foam Cannon, What is needed for the best Foam?

High PSI? High GPM?

How much would be the "Good rate" ? I've seen people saying 2000 psi + is enough, some saying more, some saying less...

There are many experts here, I am sure someone here knows the answer!

Have a great weekend!!

( Side note, I am thinking of buying a 2800 PSI Karcher washer. )

Is it possible that this Karcher ( that costs about 600$ - 700$ ) is 2800 PSI and only something like 2.5GPM ???? Is that ok ?

and I am asking this because I could buy a:

2800 Psi + 2.45GPM

OR

2350 PSI + 2.65GPM ( 25% Cheaper )

What would be better ?

From what I've read you should stick to under 2600 psi and under 2.5 gpm

Go with Higher psi in this case in my opinion, although both matter.

Both machines are compatible with the mtm hydro btw

Great thanks!
I will go with the 2800 One.

I am thinking of buying the Autogeek Hp cannon because of the fitting, there is a special one just for Karcher ( even 2 ).

I don't really know if I could fit MTM to Karcher ( I might, But I am not sure, and I don't Live in the U.S so I can't take risks =/ )

Do you know anything about that ?

Thank you! So much help!

From what I've gathered, basically, a consumer grade electric pressure washer($100-$200) will never produce the same suds/viscosity that a gas powered one will. You can find commercial grade electrics for a pretty penny that produce the same (ballpark of) specs you'd need but you could do the same with a gas powered for $3-500 less.

Apparently the MTM Hydro lists operating paramaters of 2.0-5.3 GPM and no more than 5000 PSI, with a minimum I believe of 1800, though I can't find that anywhere currently, we can assume 2000 to be safe though.

My buddy has a 1700psi 1.5 gpm and he can make enough foam to clean the car well... same water source my 3000psi 2.8 gpm produces a lot more foam... car gets clean with either one.... if you have a pressure washer 1500psi and 1.4gpm and higher and you cant produce good foam go to the hardware store and get a ph test kit see what your ph level is. I have used some well water that even with citrus wash and gloss "ph nutralizer" that couldent produce foam ph was just too high...
If you dont have a softener at your house or your garden hoses arent hooked up post softener and you find high ph to be the issue I reccommend if you want good foam and more importantly you dont want to worry about water spots check out portable RV water softener units.

Would a MTM fit to a Karcher Electric washer?
I know the HP foam cannon has a special fitting just for Karcher washers...
MTM doesn't say anything about fitting to a washer... ( weird )

Mtm rates there foam cannon for 4000psi not sure what all the rest are rated for but I wouldent worry foam wise about staying under any given psi except staying under the max rated psi
