1. A telescopic nozzle device for cleaning a surface of a vehicle, the nozzle device having:
a housing, the housing having:
a fluid inlet channel suitable for introducing a washing fluid into the housing; and
a rod opening that opens towards the inside of the housing at one end of the rod opening and opens towards the outside of the housing at a second end of the rod opening,
a hollow nozzle rod having:
a rod channel,
an inlet opening for introducing washing fluid from outside the nozzle rod into the rod channel, and
a nozzle for ejecting washing fluid from inside the rod channel to the outside of the nozzle rod,
the nozzle rod having a retracted position and an extended position and being moveable between the retracted position and the extended position, the nozzle rod extending through the rod opening in the extended position, and
a guiding system that guides the nozzle rod as it moves from the retracted position to the extended position,
wherein the guiding systems comprises:
a housing guide that is arranged inside the housing, the housing guide having a housing guide surface; and
a rod guide that forms part of the nozzle rod and has a rod guide surface that is in contact or can come into contact with the housing guide surface to guide the nozzle rod as it moves from the retracted position to the extended position,
wherein the housing guide has a lug that protrudes from an inward surface of a housing wall into the inside of the housing, whereby the housing guide surface is provided by a surface of the lug.
