As a team, our design value is to design for usability and efficiency. Usability increases dramatically from Mop toaster V1.0 to Squeeze-Roll V3.0 by adding user-friendly components and design features. To increase the efficiency of our design, we decided to use automated power instead of using any extra human efforts, by which the device reduces chances of getting Repetitive Strain Injury (RSI) for the housekeepers to most extent.
