A machine for removing painted stripes from artificial turf, comprising an automotive vehicle carrying an engine-driven blower, water pump, water tank, and a conditioner head that is flexibly connected to the vehicle and slides on the turf. The conditioner head includes an open-bottom housing that is spring-pressed down against the turf so that there is virtually no clearance under the bottom edges of the housing. The blower pulls a vacuum inside the water tank, and the latter is connected by hoses to the conditioner housing. A rotary brush inside the housing scrubs the turf to scour away previously-softened stripe paint. Behind the brush is a nozzle that directs a high pressure spray of water down into the turf to wash away the loosened paint particles, and this is followed by a roller that presses down against the turf and rolls water ahead of it. A baffle just ahead of the roller provides restricted clearance under its bottom edge for the water to flow under it, and this baffle forms the front wall of a chamber enclosing the roller, to which the vacuum suction hoses are connected. Water is sucked up by the vacuum and discharged into the water tank, where it is filtered and returned to the water pump. A rubber flap seal at the front end of the housing bears downwardly against the turf and upwardly against the underside of the housing to provide a yieldable air seal that allows a restricted flow of air into the housing when there is sufficient vacuum pressure inside the housing to overcome the resistance of the flap.
