The present invention relates to a novel miniature duster device designed to provide users with a device capable of cleaning delicate medical equipment, small electronics and other fragile items. The device preferably comprises a cylindrical body with two opposite telescoping ends. One end is comprised of a microfiber dusting component, while the opposite end is comprised of a feather dusting component. Users can selectively expand one or both ends and apply them to the object for simple and convenient cleaning. Further, the miniature duster device comprises an attachment point for a key ring for easy transportation.

A sponge roller is made of a polyvinyl acetal porous resin material having elasticity in a wet state, includes a roller in an approximate cylinder form and a plurality of protrusions formed integrally on an outer peripheral surface of the roller, and rotates the multiple protrusions to make contact with a surface to be cleaned so as to clean the surface. The polyvinyl acetal porous resin material constituting the sponge roller contains a cationic functional group.
