    Ein Saugkopf mit den beschriebenen Merkmalen ist aus DE-U 299 00 713.8 bekannt. Im Rahmen der bekannten Maßnahmen ist die Polierplatte an den Borstenträger angeschlossen. Mit einem Stellhub des Borstenträgers sind der Borstenstreifen und die Polierplatte gemeinsam an der Unterseite des Saugkopfes ein- und ausfahrbar. Bei eingefahrenen Elementen ist der Saugkopf auf textilen Bodenbelägen einsetzbar, wobei die Gleitsohle über den Bodenbelag gleitet. Zum Saugen von Glattböden werden der Borstenstreifen sowie die Polierplatte unterseitig ausgefahren, so dass der Saugkopf auf der in Arbeitsrichtung vor dem Saugmund angeordneten Borstenleiste sowie der in Arbeitsrichtung hinter dem Saugmund angeordneten Polierplatte bodenseitig abgestützt ist. Glänzende und nur wenige verschmutzte Glattböden können mit der bekannten Anordnung wirksam gereinigt werden. Durch den weichen Belag der Polierplatte werden die Böden abgerieben und ihr Glanz aufgefrischt. Etwas problematisch ist der Einsatz auf Hartböden mit rauer, unebener Oberfläche sowie auf stark verschmutzten Glatt-. böden. Bei rauen, unebenen Hartböden unterliegt der weiche, textile Belag der Polierplatte einem erheblichen verschleiß. Bei stark verschmutzten Böden besteht ferner die Gefahr, dass sich harte Schmutzstoffpartikel in die Polierfläche eindrücken, die beim Saugen empfindlicher Böden, zum Beispiel Parkettbelägen, Kratzer verursachen können.A suction head with the features described is from DE-U 299 00 713.8 known.
