Due to its lack of affordable housing and large homeless population, the city of San Francisco struggles with increasing amounts of human waste on its streets. Our system is, therefore, designed to contain and remove human fecal matter from paved surfaces. The clear dome protects the user and surrounding environment from contamination, while also allowing the user to see the cleaning process and ensure the mess is fully removed. The swiveling high-pressure jets enable the user to dislodge even dried feces efficiently and effectively. The following paper outlines the research, design, analysis, and testing involved in creating the final product.
