<p>A bottom wall (8) of an air discharging chamber (6) in a cleaner head (1) is formed with an air jetting slit (9). The air jetting slit (9) is arranged in the substantially perpendicular direction to the advancing direction (A) of a panellike body (2). A bottom wall (10) of an air sucking chamber (7) in the cleaner head (1) is provided with an air sucking slit (11) located in parallel with the air jetting slit (9). The air discharging chamber (6) includes a supersonic generator (12) therein. The supersonic generator (12) is provided with a continuous groove (13) in parallel with the air jetting slit (9). The air is turned into an air flow incorporating ultrasonic waves after being passed through the continuous groove (13), and is successively jetted from the air jetting slit (9). <IMAGE></p> |
