The WA-7 service unit, commonly known as the WA-7 waitress droid was a third-degree service droid produced by GoCorp and Utilitech during the Mondeo Modernist. The design of the WA-7 droid was typical of the era, consisting of streamlined contours, elliptical shapes and whimsical embellishments. The droid was propelled by an effective unipod wheel supported by gyro-balance circuitry. The unipod's drive impellers generated enough power for quick bursts of speed ideal for use within confined spaces such as the floor of a dining establishment. In addition, the droid's design was embellished with a metallic skirt and matching head fins.
