PROBLEM TO BE SOLVED: To realize reductions in size, weight and price in a vacuum cleaner for performing the state display of the vacuum cleaner for driving a rotary brush provided on a suction tool and the input control of an electric motor by setting the display of a display means to a stable display luminance having no flicker, and simplifying the structure of a hose and a hose tip. SOLUTION: Power is supplied to the electric motor 8 for driving the rotary brush for scraping dust adhered to a cleaning surface through electric motor fed lines 14a and 14b, and an input state to be displayed through electric motor state signal lines 17a and 17b is transmitted as signal to an electric motor state display means 12 for displaying the input state of the electric motor 8. At least one of the electric motor feed lines 14a and 14b and the electric motor state signal lines 17a and 17b is shared.
