Encouraging clean and hygienic public areas is made more difficult by urbanization and growing population density. Current cleaning techniques can sometimes be ineffective, not environmentally friendly, unsustainable to handle different variety of debris and mostly expensive as they are imported into the country. This study presents the design and construction of an innovative mechanical sweeper from locally sourced materials to handle street and walkway cleaning challenges. By utilizing simple technique and employing locally available materials, the sweeper collects debris and eliminates negative effects of gasoline powered sweeper on the environment. Sturdy features include a mop function for thorough particle removal, an adjustable lever mechanism for agility, and a flexible brush configuration for cleaning various variety of surfaces. Testing the sweeper in different conditions on different types of trash, confirms the sweeper’s ability to clean adequately as the designed sweeper with a single 24v battery and 0.5 hp electric motor gave a cleaning efficiency above 58%. The simulation and analysis of the sweeper frame using SOLIDWORKS 2018 gave a maximum displacement of 1.621x10-1 mm, maximum strain of 2.415x10-5, maximum stress of 9.167x106 N/m2 and factor of safety of 3. The results of the analysis suggest that the sweeper has been well-designed and can withstand the loading conditions it has been designed for. The application of the sweeper can ensure notable gains in environmental sustainability, operational effectiveness, and cleanliness.
