Abstract: A powder center for supplying a powder coating facility with coating powder includes a powder reservoir container and a powder conveyor for transporting powder out of the powder reservoir container in the direction of the powder coating facility. Moreover, the powder center includes a container lid that covers the powder reservoir container while powder is being conveyed and can be removed at least partly for the purpose of cleaning the powder reservoir container. Moreover, a cleaning unit for cleaning the powder reservoir container that can be moved from a parking position next to the powder reservoir container into a cleaning position inside the powder reservoir container by a manipulator is provided. Moreover, the powder center includes a controller by which the powder conveyor, the cleaning unit, and the manipulator can be controlled.
