Claims

[Scope of utility model registration request]

In a vacuum cleaner that includes a built-in dust collector and an electric blower, a detection device that senses pressure or air volume is provided in the ventilation path inside the vacuum cleaner, and the pressure detected by the detection device is connected to the detection device. Alternatively, the dust collection amount display device, overload prevention device, or electric blower installed in each part of the vacuum cleaner has the function of dividing the air volume range into at least two or more, depending on the pressure or air volume range. A vacuum cleaner characterized by being equipped with an output adjustment circuit, a control device for turning on and off a switch of a power source, etc.
