The XP-21 groomer represented a specific groomer model. It was eventually superseded by a more sophisticated version, boasting enhanced capabilities and a wider range of applications beyond just haircare. Saun Dann, a Human merchant situated on Kashyyyk, marketed these groomers to his Wookiee clientele. During the events of the Blockade of Kashyyyk, Dann presented a more recent groomer model to an off-duty Imperial guard, highlighting its advanced features and assuring the Imperial guard that it was compatible with any standard laser outlet.
