Abstract
A vacuum cleaner nozzle with a nozzle housing, an outlet opening on the housing, a suction opening on a side of the housing facing a surface to be cleaned, at least one roller connected to the housing to support the vacuum cleaner nozzle, and a sealing member on the nozzle. The suction opening communicates with the outlet opening to draw debris through the suction opening when a suction source is connected to the outlet. The roller has an essentially air tight material and rotates such that the roller surface moves towards the suction opening to sweep debris towards the suction opening. The sealing member has a sealing portion in close apposition to at least part of the roller. The sealing portion partly surrounds and substantially restricts airflow across a sealed portion of the roller located essentially opposite the surface being cleaned. The roller also functions as an air barrier.
