That was the absolute wow factor!
I never thought that there are such differences in quality of the rubber lips of the wipers! This one has just the right strength to pull all tired. Wipe only the bottom of the edge needed, etc. No water stains on the side wiper edges Perfect! And that you can replace the lip, it makes it even better.
And the built-in washer is a huge boost especially for large windows. The cover sits as slips nothing, and he gives the dirt just like back to the rinse water from how he picks it up from the window pane.
Have just every 4 double windows and 2 small windows cleaned on the ground floor in just one hour, including wipe windowsills. Was so excited that I then also all glass doors have cleaned in the flat. That has never happened before! ;-)
