Mechanical epilators use a rubber roller or coiled spring that is rotated by an electric motor. It catches the hair and pulls it out from the roots. The speed of the rollers or the coiled spring can also be adjusted in some devices. The epilator may have the option of regulating the tweezer strength which can be modified according to the type of hair (coarse or fine) that needs to be removed.

Hair must be about 1/4 to 1/3 inches long for the epilators to work. Epilators should be used with caution in sensitive areas such as face, genitals, or armpits because it can be extremely painful. Mechanical epilators cost anywhere from $50-$100 and results last about a week.
