<p>The nozzle has aspiration ducts (13, 14) arranged in a soleplate of the nozzle and connected to an aspiration tube (22) i.e. flexible hose, by a connection zone (24). The aspiration tube is connected to a vacuum cleaner and is linked to the connection zone delimited by walls (240, 242). A radius of curvature of the walls is greater than 20 millimeters, and an opening (16) is formed in the soleplate of the nozzle. The connection zone is determined by a dome shaped upper part and a lower part that is obtained from the soleplate of the nozzle.</p> |
