Attachment devices that enhance at least one of the functions provided by a suction apparatus are disclosed. In an aspect, attachment devices for suction apparatus are disclosed that comprise at least one rolling component. Such attachment devices may be removably attached to an inlet opening associated with a suction apparatus so as to allow the inlet opening to be slid by a user upon a surface with minimal effort while substantially maintaining or improving the amount of suction provided by the suction apparatus at the opening of an intake cavity associated with a given attachment device. Providing a relatively high amount of suction at the opening of the intake cavity may facilitate the intake of relatively larger and/or heavier objects into the suction apparatus, such as, for example, oak leaves.
