SURFACE-CLEANING HEAD

The invention relates to a surface-cleaning head (10) for cleaning a surface, having a hood-shaped housing (12) which is open at the bottom in a horizontal position of use of the surface-cleaning head (10) and which has a working chamber (20) in which at least one spray arm (104, 106) having a spray nozzle (108, 110) is rotatably mounted about an axis of rotation (112), wherein a cleaning liquid under pressure can be applied to the cleaning nozzle (108, 110) and the latter revolves about the axis of rotation (112) together with the spray arm (104, 106) in order to apply a cleaning liquid jet to a region of a surface to be cleaned that is covered by the housing (12) during the use of the surface-cleaning head (10). The aim of the invention is to develop the surface-cleaning head (10) in such a way that the surface-cleaning head achieves an improved cleaning result. This aim is achieved, according to the invention, in that the surface-cleaning head (10) has at least one rotationally fixedly held additional nozzle (138), wherein a cleaning liquid jet can be applied by the at least one first additional nozzle (138) to a region of the surface to be cleaned that is not covered by the housing (12) during the use of the surface-cleaning head (10)
