Suction nozzle and vacuum cleaner head with the same

A suction nozzle and a head of a cleaner having the same includes a suction hole (110) to which a suction force is applied; an air channel (120) formed as a closed region having predetermined area and depth and having the suction hole (110) therein; and scraper (140) longer than an end of an edge of the air channel, positioned in the air channel (120), and for scraping carpet fibers in cleaning a carpet. Especially when cleaning a carpet, the suction nozzle and the head of a cleaner having the same sufficiently push back carpet fibers to their root portions by the scraper (140) to suck dust and alien substances, so that the carpet can be cleaned more cleanly, a suction path through which external air is introduced is formed in a direction that a cleaning proceeds, and thus dust or alien substances can be effectively removed.
