A device for cleaning a roll of a steel strip conversion plant is configured to move parallel to an axis of the roll. At least an even number N>0 of parallel spray nozzles are oriented perpendicular to the axis of the roll. A first number N/2 of the nozzles are fixed to a first arm of a supporting member and a second number N/2 of nozzles are fixed to a second arm of the supporting member. The supporting member is coupled to an actuator, and the actuator has a travel of at least 1/N of a length of the roll.
