Design and Development of Pedal-Operated Washing Machine for Off-Grid Communities in Developing Countries

In Third World nations like Ethiopia, washing is still a burdensome and tedious exercise, left in most casesto women and children who endure chronic exposure to aggressive chemical surfactants and physicalexhaustion. Lack of electric washing machines due to unaffordability, unstable electricity supply, and poorwater pressure exacerbates the chore. To overcome these challenges, a pedal-powered washing machinehas been created, which can wash up to 12 kg of clothes in one cycle within 20–45 minutes.This revolutionary design addresses the drawbacks of conventional washing, including excessive wear andtear on garments, high expense, long washing times, ergonomic strain, and high water and energy usage.The device is made for sustainability and affordability, employing easily accessible local materials andsimple assembly and repair by local welders. As a functional, low-cost, and eco-friendly solution, thepedal washing machine offers a ground breaking alternative to off-grid and resource-scarce communitiesin developing countries.
