Abstract: A vacuum cleaner includes a cleaner body and a dust container separably mounted on the cleaner body. The dust container includes a dust collection body including an opening, a wall, and a dust separation part. A cover covers the opening of the dust collection body. An air guide is disposed at the dust collection body, the air guide having an opening provides an inflow hole through which air separated from dust in the dust separation part is introduced, and a filter accommodated in the air guide filters the air separated from the dust. When the cover uncovers the opening of the dust collection body, the filter is visible through the opening of the air guide.
