Abstract
A telescopic cleaning device is intended for projecting at least one cleaning and/or drying fluid onto a glass surface to be cleaned of a motor vehicle, such as an optical surface of an optical sensor of an optical detection system.The cleaning device includes at least one fluid distribution element, rendered movable, along an axis of elongation (X) and at the end of a movable piston between a retracted first position and an extended second position for cleaning and/or drying.The fluid distribution element comprises a distribution bar (4) inside which a fluid distribution channel (56) extends and the distribution bar is equipped with a heating device (60) integrated at least in part into the distribution bar in order to heat the fluid passing through said distribution channel.
