Totally recommended if you aren't sure yet. We have been using the Trobolo non-stop for the last 3 weeks and it does what it is supposed to. Personally, It's great to have such a comfortable toilet which additionally is completely ecological. No need for buying stinky chemicals and destroy our environment. Brilliant!
Just perfect! Really appreciate what these young guys are doing. The main principle isn't new, but the implementation is amazing. Because it does what it was created for. Emptying the buckets is simple and easy, the usage is completely odourless thanks to the exhaust system and the workmanship is of high quality and in line with the price. Keep doing what you're doing and to anyone reading this, enjoy using your toilet without wasting water. It just isn't necessary anymore thanks to Trobolo...
Annika Haas
To be honest, we were sceptical that this would work as described. But what can I say, it's even better than we hoped. We chose the model with exhaust system and there is no smell at all, zero. It's weird that this hasn't been invented before, this would have allowed us avoid years of buying expensive chemicals. By the way we already threw all of our chemicals out by now... So, thanks for the great idea!

  • 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.
