Abstract

A suction material collecting station for regenerating a filter chamber of a suction cleaner has an interface for connecting to the suction cleaner, a suction material collection container, a fan for generating a negative pressure in the suction material collection container, and an electric motor for driving the fan so that suction material contained in the filter chamber may be conveyed into the suction material collection container. The suction material collecting station has a control and evaluation unit that calculates a surroundings disturbance parameter and controls the operation of the electric motor automatically, depending on the surroundings disturbance parameter and a device parameter of the suction cleaner. The suction material collecting station has a detection device for detecting a presence parameter in the surroundings of the suction material collecting station and/or a device parameter, and/or a communication device for receiving information about the presence parameter and/or device parameter.
