发明名称 Surface cleaning head and surface cleaning arrangement
摘要 A surface cleaning head for cleaning a surface is provided that includes a housing that has a cleaning chamber surrounded by a peripheral wall and open at the bottom, and in which a cleaning nozzle is mounted on a spray arm and is freely rotatable about a rotational axis, and a jet pump for suctioning off cleaning fluid applied to a surface, the jet pump having a pump inlet channel connected to a combining channel via a mixing chamber, and a motive nozzle upstream from the combining channel. To improve the surface cleaning head, the pump inlet channel is oriented radially with respect to the spray arm and connected to the peripheral wall of the cleaning chamber, the diameter of the combining channel is 14 to 18 mm, and the distance between the motive nozzle and the combining channel is at least 10 mm.
