Abstract
A device for removing dirt and contaminants from a surface comprises a number of fibres (24) fixedly supported at one end and extending towards and engaging at a contact surface (28) the surface (2) from which the dirt and contaminants shall be removed. The fibres (24) have conveyor surfaces (32) extending obliquely in relation to the direction of relative movement between the fibres and said surface (2), said conveyor surfaces being adapted to move the dirt and contaminants away from said surface in direction transversely to the direction to said relative movement between the fibres (24) and said surface (2).
