<p>The floor cleaning device (1) has an evaluation unit (18) for determining the texture of a floor covering, where the evaluation unit is assigned with an ultrasonic sensor (13). The evaluation unit is arranged, so that the duration of reflection signals is worked in the saturation area in highly reflective floor coverings, such as laminate or cork. The evaluation unit is equipped, so that the duration of the saturation is used for evaluation in terms of the working in the saturation area.</p> |
