We recommend cleaning the Filling Chamber of your device with the Cleaning Brush after each session to remove coarse dirt. The Filling Chamber should also be cleaned at least once a week with a q-tip that has been soaked in alcohol. Please make sure that no alcohol drops into the interior of the device.
If the lower Filling Chamber Screen is clogged or shows deposits, please remove the screen by pushing it along the indentation of the Filling Chamber. This allows the screen to arch and detach itself from the notch. Insert a new screen, taking care that the edges of the screen lock in place into the groove provided.
The described cleaning process is the same for CRAFTY(+) and MIGHTY(+). Please refer to this video for detailed cleaning instructions:
