Abstract: An apparatus for facilitating the collection of leaves and/or yard debris using a portable vacuum device is provided. The apparatus includes a top surface and side walls defining an open-bottom chamber. An intake hose leading to the open-bottom chamber receives materials expelled from an exhaust outlet of the portable vacuum device and routes the expelled materials into the open-bottom chamber. The apparatus can be positioned within a yard waste disposal bag. When the apparatus has been filled with yard waste, it can be removed from the disposal bag, leaving the collected yard waste behind in the bag.
