heres one i did around 2 years ago
Hi Jouk45
Looks good, but this coupling would allow the brush to turn, which I find unacceptable. I will turn the brush on it's side to scrape birds much off the window and rotate the brush a bit to get into the corners if working from the side, ie. window above conservatory. I also sometimes use half the brush to clean the upper window sill from an angle, so I need the brush head to be fixed.
Still think that Unger's quick release system is great, although the angle adaptor is too heavy with alloy adjuster and too flimsy with plastic adaptor.
I still carry my Unger pole on the van and use it for some jobs - have 3 different brushes I use, depending on application. For example, I have a Solmon brush with a Mark2 swivel, and two Vikan ovals, 1 with 2mm jets and another with 3mm jets. I have a 35' SLX but the day to day pole is my fishing pole conversion with single trim Gardner brush - purely because of weight.
