Suction nozzle for a vacuum cleaner

摘要

The nozzle has a suction port (5) reversibly fixed in a functional position to absorb large particles of dirt. The port is inclined in the position, which is referred as a large particle dirt position, to a floor surface such that a front-sided suction port edge (9) has a distance (a) to the surface. The distance is sufficient for sucking the large particles of dirt, and the port and a suction chamber (4) are firmly connected. Supporting rollers are rotatably supported at a support element i.e. runner, and rotation axes of the rollers run parallel to a pivoting axis of the chamber.
