Window cleaner comes to our street each month.
He knows to do mine only every 3 months - for £8 - 11 windows.
I can do the downstairs windows in between with my ecloths.
I've never heard of a Karcher...... Only discovered the ecloths a couple of months ago.
Once a year at start of summer DH goes up the ladder and washes down the white plastic window, guttering, and doors.
