On The Jetsons Wiki, I'd like to learn more about Rosie the Robot Maid. Can you tell me her official model number, the name of the episode where she was first introduced, and a key detail about why the Jetsons acquired her, including any financial or availability constraints?
Navigate to 'thejetsons.fandom.com'. Click on the 'Characters' link. Locate and click on the 'Rosey' link. On Rosey's character page, identify her model number, the title of her first appearance episode, and the reason for her acquisition by the Jetsons.
State Rosie's original model number as 'XB-500'. State the name of the episode where Rosie was first introduced as 'Rosey the Robot (episode)'. State that she is an 'older model' and that she was the 'only one U-Rent A Maid had that Jane Jetson could afford'.
