A vibratory screener including a screen with an upper surface, a lower surface, and a plurality of apertures, an attachment post extending above the upper surface of the screen, and a cleaning system positioned above the upper surface of the screen. The cleaning system includes a support plate, a plurality of arms extending radially from the support plate, and at least one brush extending downwardly from each of the arms. Each brush is positioned so that the distal end of at least one of its multiple bristles contacts the upper surface of the screen. The screener further includes a collection area positioned below the lower surface of the screen and a vibration generator that vibrates the screen and the cleaning system and causes the arms to rotate relative to the upper surface of the screen.
