What the unit provider is responsible for
A portable amenity is hired equipment. The provider delivers it, positions it, services the waste system, doses the chemical, and collects it at the end. That servicing is a licensed waste activity with its own transport and disposal requirements, and it is arranged on a schedule tied to expected use. None of it is available to a cleaning provider, and a scope should say so rather than leaving the impression that a cleaner will handle the whole unit.
The practical implication is that servicing frequency, not cleaning frequency, determines whether the amenity is usable. A unit sized for two hundred people on an event day needs a service schedule to match, and no amount of surface cleaning compensates for a full tank. Where a site is unhappy with amenity condition, the first question is usually about the service schedule rather than the cleaning.
