The Cleaning Demo Days (RDD) is a bi-annual trade fair for the waste and cleaning industry, organised by the RAI Association. This trade association represents importers and manufacturers in the mobility sector. The core of the event consists of the 16 members of the cleaning vehicles section of RAI CarrosserieNL, which together represent more than 90% of the industry. Since the beginning, they have chosen to have their own event, organised by and for the members, which contributes to the success of the show.
