Abstract
A motor operated, hand held apparatus for dislodging and removing of accumulated earwax within the canal of a hearing aid. This apparatus utilizes a narrow elongated tool which has a spiral exterior surface which is to be inserted within the canal of the hearing aid and operated at high speed to remove and move the earwax exteriorly of the canal. Associated with this tool is a cover which is to be movable to different positions to limit the amount of extension of the tool to within the canal to thereby eliminate any potential damage to the electronic mechanism of the hearing aid.
