Abstract: The invention relates to a method for cleaning an optical surface of an optical system for a motor vehicle, based on a cleaning device having a first and second spray nozzles for spraying a cleaning fluid, the cleaning device being arranged relative to the optical system such that, in the cleaning position, the first spray nozzle sprays the cleaning fluid onto a first portion of the optical surface and the second spray nozzle sprays the cleaning fluid onto a second portion of the optical surface, including activating the first spray nozzle depending on a first state of at least one item of aerodynamic data, and activating the second spray nozzle depending on a second state of at least one item of aerodynamic data.

Abstract: The present invention relates to a cleaning device for cleaning at least one optical system of a vehicle, comprising an actuator which has an actuator body which delimits a chamber, a piston with the ability to move in the chamber, and a rod connected to the piston, one end of the rod emerging from the actuator body, said rod comprising at least one cleaning-fluid-spraying element formed at the end of the rod, the rod comprising at least one cleaning-fluid circulation duct which connects the chamber to said at least one spraying element, characterized in that the cleaning device comprises at least one switch activated according to the position of the piston.
