The point is to use a vacuum cleaner or duster to clean the corners and corners of the room and the top of the baseboard in the living room and bedroom. Also, dust tends to collect under the bed, sofa, and the back of the TV stand, so it seems better to clean the furniture while moving it appropriately.
