A joint venture between Utilitech and the repulsorlift company GoCorp, the WA-7 has become one of the most recognisable icons of a celebrated era now past. A third-degree service unit, the WA-series was primarily designed to wait tables in diners and fine restaurants across the Core Worlds of the Galactic Republic. Due to its renowned charisma, it has even been used successfully by Star Tours as a spokesperson. Almost every aspect of the WA-7s design has the distinctive stamp of the Mondeo Modernist movement that swept the Core Worlds in the previous century. The monopod mount, stylized skirt, backlit photoreceptors, and flamboyant head fins kindle the flame of nostalgia and drive collectors to prize these units, functional or not.

While the single wheel seems counter-intuitive, its gyro-stabilisation system is highly advanced and rarely fails. Sudden collisions are handled by small repulsors, which reliably save the droid, although any food they might have been carrying could be lost. The WA-7 excels at customer interaction. Unshakably courteous and convincingly personal, the female-oriented vocoder and animated jaw lend the WA-series an element of personality that propelled it to success. Utilitech even had the foresight to develop facial analysis programming to recognise regular patrons and problem customers on sight. Short-range communications keep the WA-7 connected with the kitchen and other staff, and in cantinas, they are often fitted with an optional beacon linking them directly to the local authorities.
