1. An architectural-structure covering, comprising:
a rotatable member;
a covering operatively coupled to the rotatable member, the covering being movable between a retracted position and an extended position; and
an external booster operatively coupled to the rotatable member, the external booster comprising:
a biasing mechanism operably associated with the rotatable member to selectively rotate the rotatable member in an extension direction, the biasing mechanism having a preload; and
a retention mechanism associated with the biasing mechanism and operable to release the preload at the extended position;
wherein the external booster is spaced apart from the rotatable member, the external booster being coupled to the rotatable member via one or more gears arranged and configured to transfer rotation between the external booster and the rotatable member.
