The Vesuvio Ultrasonic Diffuser can run on one fill of water for several hours. You have the option of running the diffuser without the light on. When the water runs out, the unit automatically shuts off. Very quiet and versatile diffuser.
The Vesuvio has a decorated metal ring in the center and allows a color changing LED light to shine through the top. Press once for a constant mist and color changing LED lights. Press again to choose a specific color to shine with constant diffusion. Press a third time to diffuse without any lights. Press again to shut the unit off.
To clean, simply wipe out excess water and oil with a dry paper towel.
