Need to know as I just upgraded the domestic Karcher to a Pro model. Minimal price difference in the m/c (after huge discount), but the accessories are an arm and a leg.
Eg foam lance £104! Discounted to £86. OK the lance is stainless v plastic.
My question is, when using a domestic Karcher machine and a snow foam lance ... do you have to reduce the water pressure to make the foam right? Or can one run at full pressure and just adjust the concentration.
Need to know as the domestic ones are £14, BUT with the commercial washer one can't reduce the pressure, it just bangs out 130 Bar!
(OK, one can actually adjust the pressure ... but this is done by changing nozzle sizes for the specific application.)
So say, if you are using the in built detergent tank, you actually reduce the pressure on the std. lance
Naturally I assume their expensive Foam lance does this automatically.
