In the context of vacuum cleaning, a suction head is provided, which includes a housing that is couplable to an air suction source of a vacuum cleaner, and two brushes in a substantially parallel arrangement in the housing. The brushes are rotatable about a rotation axis and configured to interact with a surface to be cleaned. The suction head is further equipped with a wetting arrangement that enables a direct supply of liquid from at least one liquid supplying position to at least one area of the surface to be cleaned, where the at least one liquid supplying position is in an area between the brushes and at a level of the rotation axes of the brushes or closer to surface level.
