Dance festivals, fairs, equestrian sports events and festivals on outdoor grounds are very popular. The events are well-attended and cause a lot of waste and pollute the environment if not cleared properly. Clearing a site of waste where 50,000 visitors were walking around requires a specialism and the right equipment to carry it out properly. With professional TRILO vacuum sweepers, leaf blowers, vacuum collectors and suction units you can do this. With TRILO vacuum sweepers you can, for example, clear litter spread over large areas in a short period of time. It is also possible to equip vacuum sweepers with a suction hose to easily carry out a mobile collection of large quantities of waste. Vacuum sweepers equipped with a wander hose are very suitable for collecting litter from hard-to-reach places.
