Patent ID: 8402600

Claim:
A vacuum cleaner nozzle comprising: a nozzle housing; an outlet opening provided on the nozzle housing; a suction opening provided on a side of the nozzle housing facing a surface to be cleaned, the suction opening being in fluid communication with the outlet opening to allow withdrawal of debris and dust from the surface through the suction opening when a suction source is connected to the outlet opening; at least one roller connected to the housing and positioned to at least partly support the vacuum cleaner nozzle when the vacuum cleaner nozzle is positioned on the surface, the roller being formed of an essentially air tight material and being rotatable in a direction of rotation such that a portion of a surface of the roller that is facing the surface to be cleaned is moved towards the suction opening to thereby sweep debris and dust towards the suction opening; and a sealing member positioned on the nozzle housing and having a sealing portion in close apposition to at least a portion of the roller, the sealing portion partly surrounding at least a sealed portion of the roller located essentially opposite the surface to be cleaned such that the sealing portion substantially restricts air flow across the sealed portion of the roller and the roller functions as a rotatable air barrier when the suction source is connected to the outlet opening.
