Simply revolutionary.
Whatever the field of application, installation, setup and use of Clesana’s C1 remain the same – with the same ease, same sustainability and same reliability.
Sophistication simply done.
Using the Clesana system is so easy that you won’t notice any difference compared to the sanitary comfort of your home, except that you don’t need any water to feel hygienically safe, without compromise.

1
As soon as the foil liner has been inserted, the Clesana toilet is ready to use. Flushing is similar to your home toilet: simply close the lid and choose between the “Flushing BIG” and “Flushing SMALL” buttons. Optionally, to bind fluids, the Clesana absorber can be added to the toilet “bowl”. Then, again, close the lid and select „Flushing SMALL“.

2
After pressing the flush button, the system takes over. Excretions and toilet waste are automatically sealed in foil bags and collected in a special compartment beneath the toilet seat, without any odors, germ-free and with no need for water. The system now automatically lines the toilet „bowl“ with fresh foil for subsequent use.

The fill-level indicator integrated into the display indicates when the bag compartment needs emptying. To empty, simply pull out the compartment and discard sanitary bags as household waste, care-free and without ever having to fear contact with the contents.
By the way: with Clesana even the disposal of toilet waste is now trouble-free. From toilet paper and feminine hygiene products to diapers, the foil-bag system securely seals everything at the push of a button.
