Abstract
In a suction head including a housing and at least one rotatable brush for interacting with a surface to be cleaned, a surface of the housing is provided with a plurality of grooves for facilitating transport of dirt towards an outlet opening in the surface from any position along the brush. The plurality of grooves has two sets of grooves, which are located at opposite sides of the outlet opening. Taking a rotation axis of the brush as a reference, each of the sets of grooves includes grooves having a circumferential component and an axial component, whereof, as seen in the same circumferential direction, a direction of the axial component of the grooves is opposite for the two sets of grooves.
