Laundry is one of the most common yet challenging tasks for students, travelers, and rural residents, especially where electricity and water are limited. Conventional washing machines are expensive, water-intensive, and immobile, while hand-washing is time-consuming and physically tiring. Hostel students and people in remote areas often rely on shared or manual washing facilities, leading to hygiene issues, inconvenience, and water wastage.

The Solar One-Wash Bag addresses these problems by providing a compact, solar-powered, and eco-friendly washing solution that requires only 1–1.5 litres of water and a detergent tablet. The integrated solar panel powers a mini motor that agitates clothes inside a textured washing bag, ensuring effective cleaning. It also offers partial drying through solar-heated airflow, reducing drying time. The product promotes sustainability, convenience, and independence, making it ideal for individuals who live on the go or in low-resource environments.
