Telescopic washing device

A telescopic washing device for cleaning a surface (S), the device comprising:

• a first telescopic member adapted for receiving pressurized fluid from a fluid source;
• a second telescopic member arranged to be moved by the pressurized fluid relative to the first telescopic member according to a first path between a retracted position and an extended position, the first path being linear and parallel to a longitudinal axis Z of the first and second telescopic members;
• a wiper element coupled to the second telescopic member such that the wiper element can be moved according to a second path, the second path lying on a plane XY substantially perpendicular to the longitudinal axis Z;
• a second guiding area associated with one of the first telescopic member or the wiper element and according to the second path;
• and
• a guiding element complementarily associated with the other of the first telescopic member or the wiper element configured to slide relative to the second guiding area as the first and second telescopic members move relative to each other, whereby as pressurized fluid is supplied to the first telescopic member, the wiper element is at least rotated according to the second path.
