I do not consumption again

The terrace time to eingeleutet with us, and as such some areas need to be scrubbed. Have the previously always done with the rotary nozzle, so we went fastest. Now I have time to invest in cleaner. Using super easy. Simply the trunk from Kärcher in the tank and let's go. Everything soaked and leave as 15 minutes. Then cleaned. Was no different than in the past also. No better and no worse.

Then a test ground pavilion half soaked and half not. Then cleaned. Both sides could be equally well / badly cleaned. I could here no difference seen. The consumption of cleaner is also immense. Come on about 20 square meters per liter.
