The abrasive cleaning device operates to direct streams of abrasive particles from a plurality of nozzles against a surface to be cleaned. The nozzles are recessed in a nozzle chamber and each receives a separate stream of abrasive particles from a divider unit. The divider unit receives a single stream of compressed air and abrasive particles and a supply source and separates the abrasive particles from the compressed air. The divider unit then divides the compressed air into a plurality of streams of equal pressure, and adds an equal amount of abrasive particles to each stream. A vacuum source creates a vacuum in an abrasive particle reclamation unit and in vacuum chambers connected to the abrasive particle reclamation unit. The vacuum chambers extend on each side of the nozzle chamber but are separate therefrom. Abrasive particles and debris from the surface to be cleaned pass through the vacuum chambers to the abrasive particle reclamation unit where the debris is separated from the abrasive particles. Abrasive particles collected in the abrasive particle reclamation unit are conveyed by an air stream to a particle supply unit.
