  • How do I use a TROBOLO®?

    Using a TROBOLO® differs little from using a conventional toilet. The sitting position is identical to that of a regular toilet – this applies to both men and women. Thanks to the contact-free separation system the body only touches the toilet seat. Merely urinating while standing should be avoided as the urine cannot be fully separated in this case.

  • Are odours generated during usage?

    Since unpleasant odours only develop when faeces come into contact with urine, the TROBOLO® separation system prevents a mixing of the excretions. Remaining odours and any arising moisture are also absorbed by litter which is not required in a TROBOLO® with an electric exhaust system.

  • How do I empty my TROBOLO®?

    All TROBOLO® models can be conveniently opened from above to remove the two separate containers located inside. After opening the TROBOLO®, the inside containers are sealed tightly with the help of the closures through a simple pressing or screw mechanism, which renders them air- and liquid-tight. The final step is to remove the containers which can then be transported to the emptying location.

  • What is the function of the separation system?

    By separating the excretions, odours are reduced to a minimum and the subsequent disposal of toilet waste is made easier. Unpleasant odours arise only when urine and faeces are combined which is why it is possible to do without toilet chemicals that are harmful to the environment.


Comprehensive information on TROBOLO® separation toilets

Detailed information about TROBOLO® dry toilets and the basic idea behind the development of our waterless sanitary technology can be found in the section “What is a TROBOLO®?” and on the “About TROBOLO®” page. The section “Functionlaity of the TROBOLO® System” also tells you exactly how a TROBOLO® is used in practice, what role the exhaust air systems and litter play and what advantages result from the separation of solid and liquid precipitates.

One of the major advantages of the TROBOLO® separation system is undoubtedly the effective minimization and elimination of odours, which is why we have dedicated another section to this feature in “Odourless with TROBOLO®”.

Finally, in the sections “Emptying & Disposal” and “Hygiene & Cleaning” you will learn in detail how to empty your TROBOLO® professionally, what disposal options are available to you and why you do not have to accept any compromises with your TROBOLO® in terms of comfort of use or hygiene. Finally, in the “Installation & Commissioning” section, we provide you with detailed information on the installation of our various TROBOLO® models and on other fundamental questions, such as the choice of location.
