Factual error: As a trash compactor Wall-E does not function logically. When he fills his chest compartment with garbage and runs his internal compactor, the cube that exits his body is the same volume as the trash he puts in, despite that trash having been compacted. He does not add extra trash to fill the empty space after running the compactor - there are three scenes that show him filling up only once with loose garbage and then ejecting a densely compacted cube.
Question: When Wall-E and Eve are in the repair ward, and Wall-E is misinterpreting Eve's cleaning as torture, what is the second "scene" supposed to be? I understand that the first one looks like Eve is having her arm ripped off and the third looks like Eve is having her head chopped off, but I can't figure out what the second one with the malfunctioning umbrella is supposed to be.
