A paint shaker for agitating and mixing paint and the like, and/or flowable materials in a container comprises a bucket having an open upper end for receiving the container and mounted to rotate around an upwardly sloping axis. A yoke is provided for supporting the bucket and the yoke is mounted to rotate around a separate, vertical axis intersecting the axis of the bucket at a crossover point. A motor is provided for simultaneously driving the bucket and the yoke to spin about their respective axes to rapidly mix and agitate the material in the container placed in the bucket. The bucket includes a bottom wall for supporting the container with the center of gravity of the container and its contents being continually spaced below the crossover point of the axes so that the paint container does not tend to rise and climb out of the bucket during the mixing process and thus a clamp or top is not required for retaining the container in place while mixing.
