No, unlike other vaporizers, Omura devices do not require cleaning because the flower is contained within the Flowerstick and does not actually come into contact with the device. This is a huge benefit versus other vaporizers as you are not required to purchase and use all of the cleaning instruments that other devices require. At most, we recommend turning the device upside down and tapping it lightly to knock out any flower that may have fallen out of the Flowerstick.
