Foot care devices include a battery-powered vibration motor disposed inside a water-tight housing, a foot treatment element attached to the upper surface of the housing, and surface immobilizing suction cups attached to the bottom of the housing to inhibit positional movement of the device during use. Foot treatment elements have exfoliating pumice, massaging protuberances, and/or cleaning bristles and vibrate during operation of the motor. Cushioning pads between the upper surface of the housing and the attached foot treatment element reduce rattling noises during operation of the motor. Foot treatment elements also have drain holes extending therethrough and the housing has a drain channel for draining water off the upper surface. The devices can also have one or more stabilizing platform extending therefrom. Foot pressure applied to the platform during operation further reduces positional movement. Foot care kits can have a plurality of interchangeable foot treatment elements.
