Abstract
A device for cleaning an artificial “infill turf” field includes a rotating brush assembly and a basket for receiving waste and infill material. The basket has a bottom with openings that allow infill material to be returned to the field, and a vibrator to promote separation of infill from waste. The device may include wheels connected to the brush assembly in a manner effective to rotate the brush when one or both of the wheels rotate, and a magnet for picking magnetic waste material from the field. The device may include an actuator for adjusting the height of the brushes, and a tow bar that allows the device to be positioned in an “active” orientation to sweep a field, or an “uplifted” orientation to transport the device across curbs or rough terrain. Multiple brushes and/or baskets may be provided.
