The invention relates to a suction attachment (9) for a vacuum cleaner. The suction attachment comprises a housing (11) having two edges (43, 45) enclosing an angle alpha in a corner portion. A primary suction opening (55, 59) extends in a bottom part (57) of the suction attachment along each of the two edges, said primary suction openings being connected to a connecting channel (21) which can be coupled to a suction unit (7) of the vacuum cleaner. The primary suction openings open into a secondary suction opening (61) near said corner portion. According to the invention, the suction attachment (9) comprises at least two suction portions (35, 37), wherein said two edges (43, 45), said two primary suction openings (55, 59) and said secondary suction opening (61) are provided in a first one of the suction portions (35), and at least a second one of the suction portions (37) is provided with a suction opening (67, 69, 71) which can be shut off from the connecting channel (21). By shutting off the suction opening of said second suction portion from the connecting channel, the suction power of suction unit (7) is concentrated, partially or completely, in the suction openings of the first suction portion. As a result, a comparatively high suction power is also obtained in the corner portion of the first suction portion where the secondary suction opening (71) is situated. Said corner portion thus enables a comparatively high cleaning performance to be achieved in narrow areas or corners of a surface (5) to be cleaned. In a preferred embodiment, the suction attachment (9) comprises two suction portions (35, 37) which jointly form a foot (39), which foot is rotatable about a center portion (31) of the suction attachment. Both suction portions comprise a corner portion having a secondary suction opening (61, 71) for cleaning narrow areas or corners of a surface (5) to be cleaned. The suction power of the suction unit (7) can be concentrated in each of the two suction portions by rotating the foot from a first position through +90° and -90°, respectively, about the center portion.
