The trash/garbage cart/truck robot is a minor character in WALL•E. It is a hovering cart-like garbagebot that carries Axiom trash and dumps it to the trash chutes that lead to the Axiom Garbage Disposal where WALL•A units will handle it.
The trash cart robot looks like a bit similar to MVR•A transport cart robot. But when MVR•A units are mostly white, trash cart robots are more gray in color and have black and yellow warning stripes (MVR•As have black stripes too but not the yellow ones).
Two trash cart robots appear twice in the movie, but only briefly. It is clear that these two robots are separate units, because their coloring is a little different. One trash cart robot is seen by WALL•E when he tries to reach MVR•A unit carrying EVE. It dumps trash to a trash chute near WALL•E. Another trash cart robot numbered "BQ-03" appears it is seen by EVE when it dumps trash to a trash chute that is connected to captains quarter. When Trash Cart Robot BQ-03 leaves, EVE flies through the same chute and brings the plant to the captain.
- The two trash cart robots are only seen through WALL•E and EVE's perspectives and not seen elsewhere.
