The invention is based on a wiper blade device (10a; 10b) comprising at least one wiper lip (12a; 12b) for wiping a surface (14a) and comprising at least one wind deflector unit (16a; 16b) for utilizing an airstream to press the wiper lip (12a; 12b) against the surface (14a), comprising a fluid output unit (18a; 18b) and comprising a fluid unit (20a) for directing wiper fluid to a fluid output unit, which unit comprises at least one fluid channel (22a) delimited by the wind deflector unit (16a; 16b), which channel extends along a longitudinal axis (24a; 24b) of the wind deflector unit (16a; 16b) over at least 10% of a maximum longitudinal extension (26a) of the wind deflector unit (16a; 16b).It is proposed that the fluid output unit (18a; 18b) comprises at least one further fluid channel (28a; 28b), which extends along the longitudinal axis (24a) of the wind deflector unit (16a; 16b) over at least 10% of the maximum longitudinal extension (26a) of the wind deflector unit (16a; 16b), and which is arranged at least partially outside the wind deflector unit (16a; 16b) on an outer side (30a; 30b) of the wind deflector unit (16a; 16b).
