A vacuum apparatus rotatable about an axis through a filter screen for continually removing contaminants, which utilizes an asymmetrical vacuum arm supported by a center hub, and large longitudinally extending asymmetrical vacuum orifices in portions of the arm on opposite sides of the hub, operable for removing large elements of debris, trash and the like from the screen. One of the arm portions cleans a radial outer region of the screen, and the other cleans an inner region, the arm portions being generally even in mass for balance. A knife disposed on the screen cleans and cooperates with a brush on the arm for breaking up larger elements of trash. The arm is also manually removable via a snap together vacuum seal joint, for service and cleaning.
