So far as I was with Einwäscher, puller and a bucket with Spüliwasser go. The window then looked pretty neat. Nevertheless, here and there a water stain or so. After brushing with the Kärcher equipment is no different. But the road is much faster and easier.
Because even though I just watch the window washer in our office building, I get the not so easy out. When casual disconnect the water running off with the leather absorb. No drop goes where next. I had it - professionals now please do not read on! This product you do not need and my embarrassing revelations have so far always interpret intended for dilettantes -the area under the window with terry cloth to prevent puddles on the floor at least halfway. And so I moved with my extensive equipment through the house.
Kärcher appearance. Instead of splashing buckets and Einwäscher I spray my flush water directly on, clean the Einwäscher on the spray bottle and peel off the machine absorbs the water almost completely. I wipe the window leather edges and sloppy work by and done!
So much faster than before and not worse. It's great! To "reach" I can only say that a battery charge for every 20 windows and a glass canopy sufficient.
