Suction nozzle (10, 110) for cleaning apparatuses such as vacuum cleaners, electric brushes or similar, comprising a central body (11, 111) provided with a suction chamber (30, 130), and at least two suction arms (12, 112) pivoting on the central body (11, 111) on opposite sides with respect to a median longitudinal axis (10a, 110a) of the central body (11, 111) itself, and each having a corresponding lower suction aperture (16, 116) with a determinate suction surface. Each suction arm (12, 112) can be directed with respect to the central body (11, 111) from an open position, of maximum transverse bulk, to at least a closed position of minimum transverse bulk. The overall suction surface, which comprises the sum of the suction surfaces of the suction arms (12, 112), remains unchanged for any position whatsoever of the suction arms (12, 112) with respect to the central body (11, 111).
