Abstract
A telescopic cleaning device, for a glass surface to be cleaned of a motor vehicle, includes at least one hollow conveying body (5) for the cleaning fluid, closed at an upstream end by an inlet flange (12) and accommodating a movable piston (8) which is configured so as to slide in said hollow conveying body (5).The hollow conveying body additionally accommodates a rod (14) which extends jutting out from the inlet flange and around which the movable piston is capable of sliding, the movable piston and the rod being configured so as to allow the fluid to flow between them from the inlet flange to the distribution element.A heating element (22) is arranged on the rod (14), between said rod and the movable piston (8), such that the fluid flowing between the rod and the movable piston is set to flow in contact with the heating element (22).
