Abstract: An athletic field removal/extraction and vacuuming device or apparatus configured to be pushed/pulled by a vehicle to remove residue paints and other particles, such as from indicia or logos, lettering and lines on a synthetic or other athletic field, particularly straight lines on the field. The apparatus comprises a frame having a coupling mechanism for mounting the apparatus to the vehicle. At least one sprayer sprays a chemical remover onto the indicia, which loosens or dissolves the paint. After brushing the line for paint removal with brushes, and with water added, the paint particles so dislodged, including any chemical remover and the dissolving indicia on the field are vacuumed up into a recovery tank for processing elsewhere. Also disclosed are methods of so cleaning a synthetic or other athletic fields and removing by vacuuming accumulated detritus.
