Abstract
A device (A) to detect a filtering means (14) in a water treatment unit (1) including at least one signal transmitter (13) and at least one sensor (12) to detect a signal from the signal transmitter (13), whereby the water treatment unit (1) can be set at least in a work mode or in a sleep mode. The water treatment unit (1) is configured in such a way that the work mode can only be set if at least one signal which is emitted by the signal transmitter (13) is detected by the sensor (12). A filter (14) and a suction head (3) for use in the device (A). A system including a filter (14) and a suction head (3) for use in the device (A).

A device to detect a filtering means in a water treatment unit, the device comprising:
- at least one signal transmitter;
- and
- at least one sensor to detect a signal from the signal transmitter, the water treatment unit settable at least in a work mode or in a sleep mode, the water treatment unit configured in such a way that the work mode is only settable if at least one signal emitted by the signal transmitter is detected by the sensor.
A water treatment device comprising:
- a filter;
- and
- a detector to detect the filter, the detector including at least one signal transmitter and at least one sensor to detect a signal from the signal transmitter,
- the water treatment unit settable at least in a work mode or in a sleep mode, the work mode settable only if at least one signal emitted by the signal transmitter is detected by the sensor.
