The washer goes on first with a scrubbing motion that loosens grit, and the worker watches for stubborn spots that will need a scraper. The squeegee blade is held at an angle that changes depending on how much water is on the glass. Pole work on high panes uses the same strokes with longer levers and far less feedback, and the worker reads the result from the ground. Water-fed poles with purified water are a different technique again, rinsed and left to dry with no squeegee at all.
Interior glass in offices and retail gets a spray and microfiber approach, and frames and sills are wiped as part of the job. We record from head cameras that hold the blade and the pane in frame, plus fixed cameras from inside and outside the glass where we can place them. Collection runs through full shifts on real buildings in five countries.
Episodes come per pane or per run of panes, with plain-language step labels like washing, scraping, cutting in, squeegee pass, edge wipe, and frame wipe. Panes that show streaks, drips, or missed corners on inspection get failure tags. Hand, squeegee, washer, and pole tracking are optional, and we deliver output in your schema to your storage.
Window cleaners on camera are consented and paid, and the footage is cleared for commercial model training. A sample batch takes one business day to reach you once you request it.
