... But that's really about the only criticism of the Kärcher window vacuum cleaner. Have the unit received today and (without the Kärcher concentrate) used in multiple windows with standard liquid cleaner - with outstanding results, namely without streaks and stripes - and without physical exertion, without back pain, without much time. And the windows were really dirty after the long winter ... Further applications follow (mirrors, tiles, doors).
The indications given in several reviews to storing / handling of window suction and wet the surface to be cleaned have helped me to achieve at the first use of a flawless result. Many thanks for that!
