Abstract
A window scraper has a drum that mounts four blades on its periphery, the blades extending generally tangentially so the sharp edges project beyond the drum. A shroud covers the drum and blades, and the shroud defines an opening where the blades project through the opening to engage a glass pane to be scraped. Switch actuators are placed beside the opening so the opening must be urged against a surface before the drum can be rotated. The motor and battery may be placed within the handle of the scraper. A safety shield is pivoted to the shroud, and can be used to cover the opening in the shroud when the scraper is not is use.
