PROBLEM TO BE SOLVED: To provide a high-security vacuum cleaner which can avoid the risk such as burn of its motor or the like while suppressing an increase in its power consumption when collected dust increases or its suction opening is blocked. SOLUTION: The vacuum cleaner includes: a dust container which separates dust from air sucked by an electric blower; a measuring means for current or the like which measures the current or the power consumption of the electric blower; a temperature detecting means which detects the temperature of the electric blower; and a risk avoiding process control means which controls the electric blower to shift to a predetermined risk avoiding operation status when the temperature of the electric blower detected by the temperature detecting means reaches a predetermined initial abnormal temperature set value; and further an initial abnormal temperature set value correcting means which corrects the initial abnormal temperature set value in accordance with the result of measurement by the measuring means of current or the like.
