A motor-powered depilatory device employing a hair-plucking assembly containing a right hand actuator element and a left hand actuator element, identical in construction, each carrying opposing tweezer elements, which fit together in interleaved fashion, arranged to define hair-traps, with the hair-plucking assembly being rotatable about a central shaft and operable to close and open the hair-traps by a system of cams and springs. The device is designed to allow for self-alignment of the tweezer elements, ensuring that all tweezer elements close simultaneously during a revolution of the hair-plucking assembly, with no excessive applied force being required, thus enabling uniform distribution of gripping force among all hair-traps, despite inaccuracies in manufacture. Quality of hair plucking is thereby improved, where quality of plucking is defined as the percentage of hairs plucked versus percentage of hairs cut. The actuator elements are arranged to provide slots for installation of a plurality rows of tweezer elements, arranged in a staggered, rather than tandem arrangement, which contributes to a much more even treatment of the skin surface, and to an increase in the speed of removal of hairs from a given area, thus leading to reduced energy consumption per unit of time. A further advantage of the present invention is a continuous cam design, eliminating the need to jump from one cam to another, and this configuration decreases noise levels, reduces energy requirements and reduces wear and tear of the device.
