ABSTRACT:
A swimming pool cleaning apparatus carries a scraper and deflecting member along one side of a mouth defined by a receptacle of the apparatus and in advance thereof. The scraper and deflecting member has a blade inclined towards the mouth and having a leading edge that may scrapingly engage a wall or floor of the swimming pool. The scraper and deflecting member is pivotally mounted on the apparatus by means of two legs that extend from the ends of the blade. The blade has two ribs on its underneath surface parallel to its leading edge which assist in scraping the walls of the swimming pool.
