Brush heads configured and arranged such that rotation or oscillation of the brush heads generates beneficial tuft and/or filament movement. Some brush heads include tufts of bristles having the same characteristics (e.g., materials, diameters, heights, etc.) while other brush heads include tufts having a plurality of bristles with different characteristics (e.g., materials, diameters, heights, etc.). The characteristics may be different from tuft to tuft or within each tuft. Bristle heights may be varied by employing non-planar brush head tufted surfaces, trimming bristles to different heights, etc. As a result of these configurations and others, individual bristles as well as entire tufts or groups of tufts provide three dimensional (3D) motion to the brushes. 3D tuft and/or bristle movement may provide improved cleaning, massaging, and/or exfoliating of a subject's skin. |
