In connection with a mounting device for sensors and pick-ups generally, serving as dust-detecting means for vacuum cleaners, in particular in the form of luminous diodes and phototransistors arranged adjacent the suction channel of the said vacuum cleaner, it is proposed to form at least one axial channel, leading from the inside to the outside, immediately adjacent the sensor, through which an air flow is passed due to underpressures or overpressures prevailing in the area of the sensor, which air flow acts to continuously clean the sensitive area of the sensor.

Mounting device for sensors and pick-ups of vacuum cleaners which are arranged, as dust-detecting means, adjacent a suction channel passed by the dust and dirt particles, and whose sensitive areas are exposed, at their point of installation, to contamination or to being covered up, in particular optical or electric dust-detecting means, characterized in that at least one channel (14) is arranged in the mounting area (11) of the sensor, directly adjacent the body of the sensor (12, 13) and its sensitive area, through which an air flow is guided due to the underpressures and overpressures produced by the vacuum blower itself, Whereby the sensitive area is continuously cleaned.
