i agree with you smudgerthat brush looks like it would be better for 1st cleans maybe or better for conserv roofi might get one to try for conserv roofsbut would never use it for window cleaningi carnt go back to using any brush that looks like that for window cleaningafter using the aerial brush i would end up losing to much time
lol ive just made a piece of plastic like the one in your photo to my gardiners brush,not to scrape birds poop of the window but because i found the water would run of the brush and down the pole. the reason this was happening was because the brush head was the same size as the gooseneck fitting letting the water just travel acroos.
