The Trash/garbage cart/truck robot named "BQ-03" is a minor character in WALL•E. It is a hovering cart-like robot 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.
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).
Trash cart robots appear twice in the movie but only briefly. It is clear that these robots are are two separate units because their coloring is a little different. This robot is first seen by WALL•E when he tries to reach MVR•A unit carrying EVE. The trash cart robot dumps trash to a trash chute near WALL•E. The second time trash cart robot appears it is seen by EVE when it dumps trash to a trash chute that is connected to captains quarter. When the trash cart robot leaves EVE flies through the same chute and brings the plant to the captain.
- The trash cart robot is only seen through WALL•E and EVE's perspective, and is not seen elsewhere.
