The unit functions as a charging and suction station for the RVC 3 Comfort cleaning robot.
As a charging station, the functionality is identical to the charging station supplied with the cleaning robot.
In addition, the station is used for suction. Suction starts when the cleaning robot has completed its cleaning task. During the suction process, a flap in the dust container of the cleaning robot is opened by the vacuum created and the dirt is transported into the filter bag of the station.
Suction can only take place under the following conditions:
The cleaning robot is in the station.
A filter bag is suspended in the station.
The inserted filter bag is not full.
The station cover is closed.
