Equi-Tee Shake’n Rake cleans sand and soil by auto-screening unwanted debris. As light and easy to use as a scoop, it has a battery powered motor that does the “shaking” for you, eliminating manual agitation. Easily separates glass, rocks, clay, pet waste and other objects from sand. Uses include beach and resort cleaning, infield skin spoils sifting, municipal playground sanitizing and other uses where clean sand is necessary. See this video:
