Many lay people (like me) look at the area destined mostly to the pressure can produce to a device ..... let it be !!
Because, as said the nice man from Kränzle service .... the pressure is only speeding up ..... and that is without mass (water flow) worthless !!
A good example of boxing: "Suppose a middleweight and heavyweight produce the same acceleration ....
I would not be hit by middleweights ..... and certainly not by heavyweights !!
And only the accessory makes a HD device really useful .... I can therefore produce perfect foam
I can wet sandblasting
I can suck sludge eg pond
I can clean large areas much more quickly.
But what you should rather do without the splash of Kränzle for HD lances. This plastic rubbish breaks down quickly.
And although the splash guard is transparent, .... one can sec to about 2. no longer see where one holds out the lance.
Moreover, I have read in a review that you can not roll the hose in HD are ..... that was probably improved. This works out!
I'm totally thrilled .... so much power.
