Abstract (en)

In the field of cleaning surfaces, a nozzle arrangement (1) is provided that is configured to be applied in a cleaning device and to be moved forward and backward in an advancement direction (da) of the nozzle arrangement (1) over a surface (2). The nozzle arrangement (1) comprises at least one working member (30) configured to assume one of at least two possible positions on the nozzle arrangement (1), and a member setting mechanism (40) configured to automatically set the position of the at least one working member (30) in relation to a value of at least one discrimination parameter that is influenced by motion resistance between the nozzle arrangement (1) and an actual surface (2). In that way, automatic setting of the position of the at least one working element (30) in relation to the surface type is achieved.
