Patent ID: 7467439

Claim:
A suction attachment for a vacuum cleaner comprising: a suction nozzle; a coupling member for coupling the suction attachment to a suction channel of the vacuum cleaner, said coupling member being pivotable relative to the suction nozzle about a pivot axis extending substantially perpendicularly to a longitudinal axis of the coupling member; a first brush and a second brush extending near, respectively, a front edge and a rear edge of the suction nozzle; an adjustment mechanism for adjusting the first brush and the second brush from a first position, in which the first brush and the second brush are in a retracted position relative to a bottom surface of the suction nozzle, into a second position, in which the first brush and the second brush are in a protruding position relative to said bottom surface; a rolling member configured for rolling and arranged near said pivot axis in such a position that, during operation, said rolling member extends below the first and second brush when the first and the second brush are in said first position, and said first and second brush extend below the rolling member when the first and the second brush are in said second position, wherein said pivot axis is arranged between the first brush and at least a portion of the second brush; and a blocking mechanism which cooperates with the adjustment mechanism and which blocks the suction nozzle in a blocked position relative to a central portion of the suction attachment when the first brush and the second brush are in the second position.
