I don't like waving the whole pole around when cleaning low windows, so I built a new hand held water fed brush. The brush is a simple mid range car cleaning brush, of course completed with 3D printed parts. I probably should have cleaned off the tape residue first, but was in a hurry to try it out. Taking it for a spin tomorrow. Files are as of course open source, and available at youmagine. Does anyone else use something like this? The simple jets are inspired by Richard Clue in this video.
