An apparatus for cleaning a sensor, comprising:

• a sensor that is positioned in a vehicle;
• a sensor bearing unit that is positioned on a vehicle body adjacent to the sensor;
• at least one nozzle assembly positioned in the sensor bearing unit and configured to be raised by a hydraulic pressure of inflowing washer fluid;
• a washer fluid passage that is in fluid connection with the nozzle assembly and through which washer fluid flows;
• a motor unit configured to apply a driving force so that the sensor bearing unit rotates based on the sensor;
• and
• a control unit configured to rotate the sensor bearing unit in response to a contaminated location of the sensor and apply the washer fluid to the nozzle assembly.
