Abstract
Abstract This disclosure pertains to a portable rechargeable battery operated handheld cleaning device adapted to receive various cleaning implements, such as wire brushes, abrasive wheels, and the like into one of the dual internally housed transverse cleaning implement receiving tongues. Each tongue, used singly at the option of the user, has a reciprocating motion limited to one hundred eighty degrees. Terminals are provided for recharging the batteries included in the waterproof fully immersible housing. A charging device, operating from household voltage, provides the requisite battery charging current when the handheld cleaning device is connected to it. The charging device is energized by the household current only when the handheld cleaning device is inserted into it, so as to close a charging enabling switch internally mounted within the charging device.
