Cleaning attachment for handheld rotary tool

摘要

A cleaning attachment configured for mounting a conventional household sponge to the chuck of a cordless electric screwdriver. The cleaning attachment relieves a person of the manual labor involved in scrubbing a surface with a sponge by hand. The cleaning attachment also eliminates the need to purchase a specialized sponge that is designed and sold specifically to operate in conjunction with a rotary tool. The sponge can be easily dismounted, flipped over, and reattached for continued use.
