1. An optical or optoelectronic device, comprising:
a housing;
at least one transparent cover;
a cleaning device for cleaning a surface of the at least one transparent cover with a fluid cleaning agent, the cleaning device including at least one nozzle arranged in the housing, the at least one nozzle having an outlet opening, from which a jet of cleaning agent exits along a spray axis; and
a reflector, which is at least temporarily or permanently arranged at a first distance from the outlet opening and at a second distance from the surface of the at least one transparent cover, and facing the outlet opening, wherein the reflector and the at least one nozzle are separate components spaced apart from each other;
wherein the jet of cleaning agent is directed against the reflector, so that the jet of cleaning agent is reflected by the reflector and is deflected onto the surface of the at least one transparent cover as at least two essentially flat spray jets, which are separated from one another in a circumferential direction with respect to the spray axis and are oriented in different radial directions on the surface of the at least one transparent cover.
