PROBLEM TO BE SOLVED: To provide a vacuum cleaner capable of enhancing visibility of accumulated dust.SOLUTION: A vacuum cleaner comprises: a hollow pipe; a swirl chamber which has a central axis along the central axis of the pipe, is connected to the pipe, swirls dust-containing air entering from the pipe, and separates dust from the dust-containing air; and a dust chamber which has a central axis closer to the pipe than the central axis of the swirl chamber, surrounds the swirl chamber, and accumulates the dust separated by the swirl chamber. According to this configuration, visibility of the accumulated dust can be enhanced.SELECTED DRAWING: Figure 12 |
