1. An allergen reduction device comprising:
a body having a sliding surface that is configured to be moveable along an object;
a dust cup removably coupled to the body;
a first agitator rotatably coupled to the body and disposed within a first agitator cavity defined in the body, the first agitator being configured to contact the object;
a second agitator rotatably coupled to the body and disposed within a second agitator cavity defined in the body, the second agitator being configured to contact the object, wherein the first and second agitators are configured to counter rotate to stretch the object such that a portion of the object extending between the agitators is substantially parallel to the sliding surface of the body;
a suction motor disposed within the body and configured to cause cleaning air to flow along corresponding cleaning airflow paths from the first and second agitator cavities into the dust cup;
a hot air outlet fluidly coupled to the suction motor, the suction motor being configured to urge the cleaning air along a heated exhaust airflow path and through the hot air outlet such that the heated exhaust airflow path intersects the object after exiting the hot air outlet, wherein the hot air outlet is disposed between the first and second agitators such that the cleaning air exiting the hot air outlet urges the sliding surface of the body in a direction away from the object; and
a heater positioned within the heated exhaust airflow path between the suction motor and the hot air outlet, the heater being configured to heat the cleaning air that is urged from the hot air outlet.
