1. A nozzle arrangement for a cleaning device, the nozzle arrangement comprising: a nozzle housing, a brush rotatable about a brush axis, the brush being provided with flexible brush elements having tip portions for contacting the surface to be cleaned and picking up dirt and/or liquid particles from the surface during the rotation of the brush, wherein the brush is at least partly surrounded by the nozzle housing and protrudes at least partly from a bottom side of the nozzle housing, a drive unit for rotating the brush, a squeegee element which is spaced apart from the brush and attached to the bottom side of the nozzle housing on a first side of the brush where the brush elements enter the nozzle housing during the rotation of the brush, wherein the squeegee element is configured for wiping dirt and/or liquid particles across or off the surface to be cleaned during a movement of the cleaning device a deflector for contacting the brush and deflecting the brush elements during the rotation of the brush, and a restriction element for at least partly restricting air from getting sucked into the nozzle housing at a second side of the brush where the brush elements leave the nozzle housing, wherein the restriction element is, seen in a rotation direction of the brush, arranged behind the deflector, such that the brush elements, during the rotation of the brush, contact the deflector before passing the restriction element and then leaving the nozzle housing at the bottom side, characterized in that the restriction element comprises a mechanically flexible element that is, due to its flexibility, configured to follow an outer surface of the brush and to contact the tip portions during the rotation of the brush.
