1. A surface cleaning apparatus comprising:
a cleaner body having a handle and an inlet;
a dust cup removably coupled to the cleaner body and configured to pivot about a pivot point between at least three indexed positions and configured to be selectively retained at each of the at least three indexed positions, the at least three indexed positions including:
a first position, when in the first position, the dust cup is fluidly coupled to the inlet such that an airflow path extends from the inlet and into the dust cup;
a second position, when transitioning from the first position to the second position, the dust cup pivots away from the inlet such that, when in the second position, the dust cup is fluidly decoupled from the inlet by exposing an inlet end of the dust cup; and
a third position;
a dust cup spring configured to urge the dust cup from the first position towards the second position;
a slidable stop configured to prevent unintended movement of the dust cup between the second position and the third position, wherein the slidable stop is caused to slide in response to a user exerted force on the dust cup, sliding of the slidable stop allows the dust cup to transition between the second position and the third position, the user exerted force causing the dust cup to pivot; and
a stop spring configured to urge the slidable stop in a direction of the pivot point, wherein a dust cup spring biasing force of the dust cup spring is:
less than a stop spring biasing force of the stop spring such that unintended movement of the dust cup from the second position to the third position is prevented; and
configured such that unintended movement of the dust cup from the second position to the first position is prevented.
