A cleaning system has a base unit and a separably connected accessory device. The base unit has a detection device for detecting the type of accessory device connected to the base unit, a base memory and a control device for controlling an operating activity of the base unit and/or the accessory device depending on the type of connected accessory device. The accessory device has a configuration memory, in which configuration data for configuring the base unit and/or the accessory device for an operation of the cleaning system is stored. The control device of the base unit reads the configuration data stored in the configuration memory and stores this configuration data centrally in the base memory. The control device accesses the configuration data stored in the base memory for an operation of the cleaning system and adjusts the base unit and/or the accessory device based on the configuration data.

Cleaning system comprising a base unit and at least one accessory device

An apparatus for cleaning a floor surface including a control unit, a cleaning member for picking up dirt from the floor surface by moving the cleaning member, and an electric motor for moving the cleaning member. The electric motor is such that relative movement between a stator and a rotor of the electric motor can lead to an induction of a voltage and a reverse current. The control unit is configured such that a power supply of the electric motor is temporarily interrupted during a cleaning operation of the floor surface, and the control unit identifies a present surface condition of the floor surface currently being cleaned by means of the cleaning member on the basis of a detected current curve of the electric motor.
