Abstract
A device for automatically controlling the suction power of a vacuum cleaner, in which at least one diaphragm-actuated vacuum switch is so arranged in the vacuum region of the vacuum cleaner that, depending on the variation in the air pressure as a result of external operating conditions, a contacting is produced which leads to a switching of the speed control range of the vacuum cleaner motor. The switching of the instantaneous suction power takes place in steps, two diaphragm switches having three contacts each being preferably provided.
