Abstract: Surface cleaning device for cleaning an floor surface comprising an inner space forming casing and a liquid dispenser positioned in the inner space. The liquid dispenser 3 comprises a motor driven rotor shaft which defines an axis of rotation. Rotor arms extend radially away from a rotor shaft. Each rotor arm comprises a blade to thrust a volume of liquid medium away from the inner space in a driving direction towards a casing outlet. The liquid dispenser comprises at least one nozzle for jetting a stream of liquid onto the floor surface. The at least one nozzle has a central axis which is inclined positioned in a forward direction with respect to the driving direction under an angle of inclination with respect to the axis of rotation.
