Street sweepers are an indispensable part of urban cleaning. Unlike ordinary indoor cleaners, street sweepers need to face the outdoor environment and fields. Because of the long distance and extensive area, street sweepers have developed their own clean process. Due to the environment and process, street sweepers have more needs for cleaning tools. For example, carrying mobility. Through observations and interview, researchers found that different types of work and vehicles are used by street sweepers. After analyzing the advantages and disadvantages, different types of works can be merged into one new process. Then, use the insights found in the interview to design a new clean equipment set. This set can accord with the new process and meet street sweepers needs. In the design part, sketches are used to develop multi ideations. Then 3D printers are used to make prototypes to verify the usability of mechanism. In this study, a portable clean cart is proposed. It can reduce the size to be suitable for motorcycle carrying, and also expand the structure to facilitate the garbage bag. The newly designed broom and dustpan can easily fit into the cart. Since street cleaning system developed so far, though Taiwan has employed street sweep machine, still there are many special street types that can only clean by the human. Therefore, study for the work experience of street sweepers is valuable.
