OoYes Invests €1 Million in Vacuum Toilets and VIP Sanitary Trailers
OoYes is making a strategic €1 million investment in vacuum toilets, including modular vacuum units and VIP sanitary trailers, with one clear goal - to introduce a new standard for mobile sanitation solutions wherever high-quality sanitary conditions are required and sewage infrastructure is not available.
This is not just a portfolio expansion. It is a shift in how people experience concerts, festivals, and large-scale events.
As part of this investment, all OoYes locations across Bulgaria - Sofia, Plovdiv, Varna, Burgas, Veliko Tarnovo, and Ruse - will be equipped with vacuum systems and VIP sanitary trailers.

A €1 Million Investment in a New Standard
OoYes is the first company in Bulgaria to introduce vacuum sanitation solutions for events — a technology that has long been the standard across Western Europe.
With this €1 million investment in vacuum toilets, the company is not only reinforcing its leadership position but also expanding the availability of high-end mobile sanitary solutions on the Bulgarian market.
What Do Vacuum Sanitary Systems Include?
- VIP vacuum toilet trailers with self-contained systems (fresh and wastewater tanks), designed to serve large numbers of people efficiently without queues
- Modular vacuum toilets with flexible capacity, adaptable to the size of the event and number of visitors
- Fast installation without the need for heavy machinery
- Up to 90% lower water consumption per use
This €1 million investment enables OoYes to deliver a level of scale, efficiency, and quality that has not previously been available in Bulgaria.
Better Conditions = Higher Consumption and Longer Stay
Sanitary conditions are often overlooked - but the impact is clear. When conditions are poor, people change their behavior.
At events with low sanitation standards, visitors tend to:
- avoid food and beverage consumption
- limit their time on site
- leave earlier
Vacuum toilets eliminate this problem.
Data shows up to 40% higher food and beverage consumption when sanitary facilities are clean, comfortable, and easy to use.

5 Reasons Why People Choose Vacuum Toilets
- Real cleanliness
Vacuum technology removes waste instantly and prevents accumulation. - No unpleasant odors
The absence of odors eliminates the main psychological discomfort. - Less water, better hygiene
Up to 90% lower water consumption per use. - Efficient service for large crowds
Less waiting, better flow, and reduced pressure on facilities. - Comfort for visitors
When facilities are clean and comfortable, people stay longer and enjoy the experience without concern.
This is a natural response. People don’t avoid events - they avoid poor conditions.
Proven Results at Real Events in Bulgaria
OoYes vacuum solutions have already been successfully implemented at key events, including:
- Midalidare Rock In The Wine Valley — the first festival in 2025 to raise the standard and introduce a higher level of comfort
- SPICE Music Festival
- Teen Boom Fest
- Zheravna Folk Costume Festival
Audience behavior is clear - visitors actively choose vacuum toilets, even when other options are available.
Setting the Standard in Bulgaria
The €1 million investment in vacuum toilets is just the beginning.
OoYes will continue to develop innovative solutions that:
- improve visitor experience
- support event organizers
- raise standards across the entire sector
Vacuum toilets are no longer a luxury. They are the new standard - and that standard is already here.
