A cleaner head is disclosed which comprises: a cleaning fluid spraying nozzle formed at the center of the bottom of the cleaner head; a leading suction nozzle and a leading brush (or a leading portion of a brush); and a trailing brush (or a trailing portion of the brush) and a trailing suction nozzle. The leading suction nozzle sucks free dirt, and the leading brush (or the leading portion of the brush) performs dry scrubbing for free dirt and adhered solidified dirt. The trailing brush (or the trailing portion of the brush) performs wet scrubbing in cooperation with the sprayed cleaning fluid, and the trailing suction nozzle performs suction for the mixture of the dirt and cleaning fluid. According to the present invention, the cleaning can be done more thoroughly.
