The TROBOLO LunaBloem is made of high-quality FSC®– certified 15mm and 12mm alder plywood, material wich is extremely robust and sturdy despite its low weight. The separating system ist made of durable plastic and is surface sealed.

Electric exhaust system (optional)

The electric exhaust system is particularly recommended if you will be using your TROBOLO regularly and continously. It can be flexibly connected via the supplied mains plug with USB connection (12V, 24V or 230V) and has an extremely low power consumption. The max. current is 0.26 A, the max. power consumption 1.3 W and the noise level 19.3 dB. The electric exhaust system can be operated via a regular power connection or for example a powerbank.

Shipping & set-up

We will send your TROBOLO LunaBlœm to your home fully-assembled, so that all you need to do is to set it up in a dry, level place. Additional fastening is not necessary, but can make sense if you want to use your TROBOLO in a camper van or van, for example. It can then be attached by simply screwing it to the floor or to a wall. No lateral distance to the wall is necessary, as the two internal containers are removed from above.

The TROBOLO LunaBlœm is available in different versions, and are completely odour-free when in operation thanks to the use of litter or an electric exhaust system. If you plan to use your TROBOLO regularly, we recommend an electric exhaust system, as this allows for more comfortable and efficient use when using your TROBOLO continuously. If necessary, you can direct the odours outside via our exhaust pipe and the electric exhaust system. For occasional use, for example on weekends only, the use of litter instead of an electric exhaust system is enough for odourless, self-sufficient toilet comfort. Optionally, an additional use of our natural exhaust system in combination with litter is possible in order to discharge residual odours and moisture outside without electricity.

The possible areas of use for the TROBOLO LunaBlœm are numerous due to its compact dimensions and self-sufficient mode of operation. The most popular areas of use for the TROBOLO LunaBlœm include the garden, a house, a tiny house as well as campers and vans. The rounded look makes the TROBOLO LunaBlœm a true one-of-a-kind design that fits perfectly into any room concept and provides maximum toilet comfort for both regular and occasional use.

Absolute recommendation for those who are not sure yet. The Trobolo has been in continuous use for three weeks and does exactly what it should. I think it's great to have such a comfortable toilet and that it's completely ecological. So don't buy stinking chemicals and destroy the environment. Excellent!
What an outstanding concept that these guys came up with. I agree with the other commentors. I also wasn't sure if this was the right thing for me but now me and my man are totally convinced. The toilet seat is very comfortable and there isn't much almost any odour at all (we've got the trobolo without exhaust system) and the customer service is friendly. I recommend the Trobolo to anyone as it is much better than any other composting toilet and a chemical toilet would be much worse.
I own a Trobolo for 4 months and am very satisfied. I use it as an indoor toilet without exhaust system and it works beautifully without any unpleasant smells. At the beginning I had my doubts, but these were gone quickly. The developers did a good job, nice workmanship, quick in answering questions!!!

  • 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.
