I was skeptical, had actually Kärchermodell had in mind, but this was priced lower. Then the acid test. Single-family house, 2 floors, all windows in one day. And it works! Soaping windows / brush and simply pull the sucker! in 3 and a half hours all done! Light pressure is sufficient. All without leaving streaks, no residual dirty water, everything is clean and pure. So makes window cleaning almost a bit of fun.
