Une pluralité d'ajutages (20) sont reliés à l'extrémité distale de la série de bras (16) au moyen d'un support d'ajutage (18). Des organes de conduites (30) reliant les ajutages à la source d'abrasifs et de fluides sont disposés à l'intérieur de chaque bras abritant ainsi les conduites de tout endommagement pendant la manipulation des bras. L'extrémité proximale des séries de bras est reliée à un tambour (22) logé de manière rotative à l'intérieur d'une enceinte (24). Le tambour est entraîné par un moteur. Un mécanisme de frein (96) est relié à l'enceinte de manière à freiner le tambour (22) pendant le fonctionnement du moteur. Un dispositif d'actionnement (36) est relié à chacun des bras de manière à les faire tourner autour de leurs axes de rotation respectifs. Le dispositif d'actionnement est commandé soit manuellement soit par un micro-ordinateur. Le micro-ordinateur reçoit des informations sur la position de rotation à partir d'un détecteur et dirige le jet de fluide et d'abrasifs émis par les ajutages (20) de manière à tracer un motif géométrique particulier, nettoyant ainsi une zone de la surface de travail.
