max-W 100, also known as "Max, the Janitor Droid", was a cleaning droid. This droid was employed at the Droidnostics Center, which was located within the Star Tours travel agency.
Although Max was a diligent worker, it occasionally released carbon dioxide as a means of relaxation. Before its assignment at Star Tours, it had previously been employed at Matsushita Electric. The nickname "PanaRobo" served as a constant reminder of its previous occupation.
The origin story of this droid is rooted in a "Spot the Droid" poster that was on display at the Tokyo Disneyland Star Tours, with a translation provided by the EndorExpress.net fan site. A significant portion of the same details can also be discovered in the Complete Guide to Star Tours informational booklet.
