The Simonis X-1 works by static electricity and by capillarity. It is therefore a very flexible and rapid back and forth movement and not the exaggerated pressure which would be needed for the optimal effectiveness of a brush. The Simonis X-1 possesses a high absorption capacity and can easily retain the dust of half a chalk in its textile structure. Once the Simonis X-1 no longer seems to retain the chalk, all one has to do is release the dust absorbed by the high-tech structure to restore its initial effectiveness. To do this, we recommend that you:
- either vacuum the textile structure
- or beat/slap the structure with your hand.
(do not hit the Simonis X-1 against a hard surface which could damage the X-1 or that same surface; do not clean the textile surface with any liquid) Please note however that the textile surface will retain the colour of the chalk, even after having been emptied. This colouration is normal and in no way alters the effectiveness of the Simonis X-1. The Simonis X-1 can absorb any sort of fine dust provided that it can be integrated into the high-tech structure of the X-1.
