The present invention discloses a sensor cleaning device (3) for cleaning an exterior sensor surface (4) of a sensor (2), in particular an optical camera or a LiDAR, for use in automotive applications, comprising—a dispensing device (6) with a cleaning liquid dispensing unit (7) for dispensing a cleaning liquid (8) towards the exterior sensor surface (4) of the sensor (2)—a collecting unit (12) for collecting cleaning liquid (8) dispensed from the dispensing device (6) towards the exterior sensor surface (4), wherein—the dispensing device (6) comprises a receiving fluid 7 connector (9) for receiving the cleaning liquid (8), and—the collecting unit (12) comprises at least one return fluid connector (17) for releasing collected cleaning liquid (8). The sensor cleaning device (3) is characterized in that,—the collecting unit (12) comprises a movable cover element (13). which is movable between a protruding position, in which the collecting unit (12) collects a maximum amount of the cleaning liquid (8) dispensed from the dispensing device (6) towards the exterior sensor surface (4) of the sensor (2) via its collecting opening (15), and a retracted position, in 10 which the cover element (13) is retracted into a position out of a field of view of the sensor (2). The present invention also discloses a sensor unit (1) comprising a sensor (2), in particular an optical camera or a LiDAR, for use in automotive applications and an above sensor cleaning device (3).
