Electric vacuum cleaner

An electric vacuum cleaner is provided and includes a secondary battery (16); an electric blower driving unit (12) which drives an electric blower (11); an electric blower control unit (13) which sends driving signals to an electric blower driving unit (12); a main body control section (21) that sends a drive signal to an electric blower control section (13) based on an input of a close-up operation section (8); a battery remaining power notification unit (23), which informs the remaining power of the secondary battery (16). When judging the remaining power of the secondary battery (16) basedon the output of the main voltage detection unit (22), the main control unit (21) sets different judgment voltages and different judgment time according to the operating state of the electric blower (11) to judge the remaining power of the secondary battery (16) and control the operation of the electric blower (11). Thus, an emergency stop of the operation of the vacuum cleaner in operation can beprevented in advance. 提供一
