By this operation, the floating dust suction electric blower 41 can suck indoor floating dust and clean the indoor air even when it is not cleaned, and functions as both an electric vacuum cleaner and an air cleaner. The user can provide a user-friendly vacuum cleaner.

  In addition, when a plurality of floating dust suction electric blowers 41 are provided, for example, if one is provided on each of the right and left sides of the outer shell of the cleaner body 2, the ability to collect the floating dust is doubled. If one is added to the top of the vacuum cleaner main body 2, the ability to collect floating dust can be tripled, so that the ability to collect floating dust in the air can be doubled.

  As described above, the vacuum cleaner according to the present invention can collect dust suspended in the outside air in the cleaning room without reducing the floor dust suction performance, which is the original function of the vacuum cleaner, and only the floor surface. It is effective as a vacuum cleaner that can also remove dirt in the air.
