According to this construction, the floor nozzle of the electric vacuum cleaner of this embodiment is moved along the floor surface. At this time, the running tire is pushed upward by a certain displacement due to the weight of the floor nozzle. The displacement is as follows depending on the type of floor surface and the condition of use. When moving on a carpet, the displacement of the running tire changes intermittently due to the unevenness of the carpet. Further, when the floor nozzle is tatami and moves on a hard floor, the tire displacement is kept substantially constant. Further, when the floor nozzle is lifted above the floor surface, the tire displacement becomes zero. That is, the switch is turned on and off depending on the type of floor surface and the usage state of the electric vacuum cleaner. Therefore, when at least two tires for traveling are arranged, the type of the floor surface and the usage state are determined by using the floor surface determination circuit and the control circuit configuration to determine whether the switch is turned on or off, and the rotation of the rotary brush is controlled. be able to. Furthermore, the suction force of the vacuum cleaner body can also be controlled using the signal output from the control circuit.
