Abstract:
A suction attachment (9) for a vacuum cleaner comprises a housing (11) having two edges (43,45) enclosing an angle ( in a corner portion. A primary suction opening (55, 59) extends in a bottom part (57) of the suction attachment along each of 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. Said 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. In a preferred embodiment, said two suction portions (35, 37) 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 about the center portion.
