Abstract: A method for evaluating a particle signal with an evaluation unit associated with a control device includes generating a particle signal by a sensor within a flow element, the particular sensor being dependent on a number of particles in a two-phase flow generated when cleaning a surface by a suction device connected to the flow control element. The method further includes determining in the evaluation unit from the particle signal a control signal for further controlling an actuator controlled by the control device. A speed of movement of the flow element over the surface is taken into account in the determination of the control signal.
