This is an overview of our project to design an expandable brush. This brush is designed to be versatile and able to clean a variety of vessels with narrow necks, wide bases, and complex geometries. Our prototype consisted of two parts: an outer sleeve with a deflector and a handle with a head piece to hold our bristle filaments. This design allows the user to insert the brush into a vessel and then control how far outward the bristles expand for easy cleaning.
