Abstract: A massaging device has interchangeable heads which provide a deep muscular petrissage, and a deep transverse or circular friction. The device has a variable speed power drive, a transmission and a receptacle handle with a snap connector for replaceable massage heads. One of the massage heads connects to the snap connector and has a number of substantially similar cylindrical fingers made of resilient material, protruding from a disc portion, evenly spaced apart in a circle about the axis of rotation, and a straight sided finger in the center of the circle. Another massage head has a non-rotatable disc portion with at least two rotatable eccentric cylindrical fingers made of resilient material, the fingers evenly spaced from the axis of rotation and a connection to the drive to rotate the tips of the fingers in counter rotating directions.
