SELF-PROPELLED VACUUM CLEANER

摘要

PROBLEM TO BE SOLVED: To provide a self-propelled vacuum cleaner capable of performing efficient cleaning with less cleaning omission on a floor surface.SOLUTION: A self-propelled vacuum cleaner includes: a main body having drive wheels and moving on a floor surface by the rolling movement of the drive wheels; a first side surface and a second side surface that are formed of flat surfaces constituting the side surfaces of the main body; a first dust suction port arranged in the bottom surface of the main body and formed to allow a longitudinal direction to be in parallel with one of the two flat surfaces; a second dust suction port formed to allow a longitudinal direction to be in parallel with the other one of the two flat surfaces; a first rotary brush arranged inside the first dust suction port; and a second rotary brush arranged inside the second dust suction port. The first side surface and the second side surface are arranged to allow the vertex angle formed by the mutual surfaces to be about 90°. The drive wheels are configured to be rolling-movable in a direction to be in parallel with a bisector of a vertex angle to be formed by the first side surface and the second side surface.
