Abstract
An autonomous cleaning device that may reduce noise caused by friction with a floor includes: a main body having an opening; a brush unit that is rotatably disposed in the opening of the main body; and a blade assembly that guides introduction of dust swept up by the brush unit, the blade assembly including: a blade that guides dust toward an inner side of the main body; a support member that is coupled to the blade so as to support the blade and that has one side in which a coupling groove is formed; and an insertion member that is inserted into the coupling groove of the support member. The autonomous cleaning device can prevent noise from occurring due to abnormal contact between the blade and the floor while the autonomous cleaning device travels.
