This boom finally meets my expectations. A bit expensive for occasional use but the quality "kärcher". I can finally clean my skylight that is in my stairwell without any danger. For years, I was looking for a simple solution. I finally found !!! Just a small problem, perch kärcher with the windshield washer is a little heavy for me to handle! but that is normal in view of the height of the device at the end of the pole! So no complaints but I prefer to indicate that women are informed and do not have to surprises !!!
