Are the wiping pads suitable for the washing machine? Because, on the one hand, I don't really trust the built-in cleaning function and it is supposed to leave some residual dirt on the base plate, so some maintenance is supposed to be necessary here. On the other hand, the drying function is not very quiet and takes some time. Therefore, I would like to be able to switch off these functions and have spare mops ready to wash the used ones thoroughly.
