Abstract
A floor nozzle for a vacuum cleaner has a housing, and a base on the housing constructed for sliding in a working direction on a floor and formed with a downwardly open slot-shaped port delimited relative to the direction between a transversely extending front port edge and a transversely extending rear port edge. The base has, extending forward from the front port edge, a part-cylindrical and downwardly convex front surface with a front radius of curvature and centered on a transversely extending symmetry axis and, extending rearward from the rear port edge, a part-cylindrical and downwardly convex rear surface having a rear radius of curvature also centered on the symmetry axis. The housing is constructed for movement of air upward through the port.
