The invention relates to a telescopic washing device (1). The telescopic washing device comprises: a body (10) having an inlet (11) and defining a chamber (12) for receiving the washing liquid, a movable member (20) having a piston (21) fluidly connected to the chamber (12) so that pressure of the washing liquid in the chamber (12) can move the movable member (20)between two following positions; a retracted position, and a maximum output position, the movable member (20) having an outlet connected to a spray member, and a control member (40) used for controlling the washing liquid and extending into the conduit (22) when the movable member (20) is in the retracted position, the control member (40) having a peripheral surface (41), a seal (50) comprising an elastically deformable portion (51) to prevent flow in the conduit (22), the seal (50) is connected to the piston (21) so that the elastically deformable portion (51) bears against the peripheral surface (41). The peripheral surface (41) has passages (42) configured so that the washing liquid flows when the elastically deformable portion (51) is situated facing the passages (42).
