How can I open the upper grate from inside the ducts?
  • 1 of 11: Only one grate can be opened from inside the ventilation ductwork.
  • 2 of 11: It is the only one that looks "different" from the others.
  • 3 of 11: It has two screws and handles on it.
  • 4 of 11: Maintenance robots are supposed to do this job, so none of your tools will fit.
  • 5 of 11: You don't need a whole robot, just part of one.
  • 6 of 11: You can get a hand from the broken robot.
  • 7 of 11: The hand is hanging loosely on the left side.
  • 8 of 11: Cut it off with the blade.
  • 9 of 11: Use the hand on the grating.
  • 10 of 11: Push on one of the handles.
  • 11 of 11: More forward to go into the hallway. Move backwards to go back into the ducts.
