shavers are water-resistant, allowing the user to clean the shaver in water. In order to ensure electrical safety, the charging/power cord for the shaver must be unplugged from it before the unit is cleaned using water. Some shavers are labeled as "Wet/Dry" which means the unit can be used in wet environments, for wet shaving. Such models are always battery-powered and usually the electronics will not allow turning the unit on while the charging adapter is plugged-in. This is necessary to ensure electrical safety, as it would be unsafe to use a plugged-in shaver in bathtub or shower. Philips/Norelco produced CoolSkin and NIVEA FOR MEN shavers that were designed specifically for wet shaving using special NIVEA gel in special cartridges. Lady shaver A lady shaver is a device designed to shave a woman's body hair. The design is usually similar to a man's foil shaver. Often a shaving attachment is a feature of an epilator which is supplied as a separate head-attachment (different from the epilating one). Body hair shaver Traditional men shavers are designed for shaving facial hair. However, products such as BodyGroom by Philips/Norelco are made specially to facilitate shaving of body hair.
