The present invention relates to a multi-stage hook device for removing livestock manure in livestock barns. More particularly, the invention is directed to a device for removing contaminants (such as feces and the like) from the floor of a livestock barn. A first and a second hook portion having hooks with different projection lengths, and a brush member, are formed integrally in a horizontally aligned structure, so that various contaminants of different sizes in a large-area livestock barn can be easily and quickly scraped off and removed.
