摘要

Device (20) for extracting liquid from a wiper body (14) held on a wiper head of a surface cleaning device under formation of a wiper surface (15) comprises a container (21) containing a wiper body holder (45) receiving the wiper body and a drive device rotationally driving the wiper body holder about an axis of rotation (55). The wiper body holder has a recess (49) in which the wiper body in inserted with the surface normal (16) of the wiper surface at an angle to the axis of rotation. Preferred Features: The recess receives the wiper body with the surface normal of the wiper surface perpendicular to the axis of rotation. The recess has a guide with two parallel U-shaped guide elements (46, 47) in which the wiper body is inserted. The drive device is a drive motor consisting of a rechargeable energy supply unit.
