6 Wake up the robot
Place your robot in front of the dock, then slide it toward the dock, lining up the
metal charging contacts. After a few minutes, a sound will let you know it's awake.
NOTE: Your robot comes with a partial charge, but we recommend
that you charge the robot for 4 hours prior to starting the first
cleaning job.
To remove your robot from the dock, slide the robot towards you and
then lift.
