RT journal article T1 Performance Analysis of Urban Cleaning Devices Using Human–Machine Interaction Method A1 Alonso García, María A1 García Sánchez, Ana A1 Jaén Moreno, Paula A1 Fernández Rubio, Manuel A2 Ingeniería Mecánica y Diseño Industrial K1 experience design K1 product evaluation K1 human–machine interaction K1 service industries K1 work productivity K1 human performance K1 human factors K1 industrial design AB Presently, several jobs require the collaboration of humans and machines to performdifferent services and tasks. The ease and intuitiveness of the worker when using each machinewill not only improve the worker’s experience but also improve the company’s productivity andthe satisfaction that all users have. Specifically, electromechanical devices used to provide cleaningservices require complex interactions. These interactions determine the usability and performance ofdevices. Therefore, devices must have appropriate ergonomic arrangements for human–machineinteractions. Otherwise, the desired performance cannot be achieved. This study analyzes theperformance of an urban cleaning device (pressure washer on a power take-off van) using human–machine interaction method. The method measures visceral and behavioral levels (set by Norman)and service times. Using these measurements, the usability of the pressure washer is determinedaccording to different factors that facilitate the operator’s well-being in the working environment.A pressure washer from Feniks Cleaning and Safety, Limited Company, has been studied. Sixteenerrors related to ergonomics, usability and safety were identified in this machine, which operates inmore than 40 locations in Spain. Therefore, this study provides valuable information on the usabilityand performance of pressure washers, as well as possibilities for improvement.
