Abstract
Described is a self-cleaning vacuum cleaner accessory apparatus, method, and system including a tubular element, a nozzle, and a nozzle housing that can include at least one nozzle housing notch. The apparatus can further include a bristle plate coupled to the nozzle housing. The bristle plate can include at least one bristle and at least one tabular release element to control the movement of at least one bristle plate tab. The at least one bristle plate tab can be coupled to, or decoupled from, the at least one nozzle housing notch to either permit or prohibit the bristle plate's movement with respect to the nozzle housing. The bristle plate can further include a pivot for rotating the bristle plate to invert the at least one bristle's orientation. Once inverted, airflow from a vacuum can remove debris from the bristles before returning the bristle plate to its original orientation.
