Die Trägerplatte ist mit Borstenleisten ausgerüstet, die in Arbeitsrichtung vor und hinter dem Saugmund angeordnet sind. Die Borstenstreifen sind biegesteif ausgebildet und halten beim Saugen auf glatten Böden den Saugmund in einem konstruktiv genau vorgegebenen, definierten Abstand zum Untergrund, um ein Kratzen der Saugmundkanten auf der Bodenfläche zu verhindern, die Schiebekräfte gering zu halten und einen die Saugwirkung bestimmenden engen Arbeitsspalt zwischen den Saugmundkanten und dem Untergrund zu gewährleisten. Neben ihrer Funktion als Tragelemente sind sie zugleich Dichtelemente, die den Bereich unter der Düse, insbesondere den Saugmundbereich, gegen unkontrollierten Luftzutritt abschotten und sicherstellen, dass sich im Bereich des Saugmundes ein ausreichender Saugunterdruck einstellen kann und an den Arbeitskanten des Saugmundes eine hohe, saugwirksame Luftgeschwindigkeit erzeugt wird.A suction head of the construction described is for example known from EP-A-0 125 994. The carrier plate is with Bristle strips equipped in the working direction in front and are arranged behind the suction mouth. The bristle strips are rigid and stop when vacuuming smooth floors the suction mouth in a structurally precisely specified defined distance from the ground to a To prevent scratching the suction mouth edges on the floor surface to keep the pushing forces low and the The narrow working gap between the To ensure suction mouth edges and the surface.

The rubber lip slides on the floor and seals the area behind the suction mouth against uncontrolled air access.

    Ein Saugkopf des eingangs beschriebenen Aufbaus ermöglicht eine gute Staubaufnahme sowohl bei glatten Bodenbelägen als auch bei textilen Bodenbelägen. Gleichwohl wirkt ein glatter Hochglanzboden nach der Saugreinigung häufig etwas stumpf. Ferner können die Borstenstreifen und/oder Gummilippen auf empfindlichen Böden Streifen hinterlassen.A suction head of the construction described at the beginning enables good dust absorption both on smooth floor coverings and also with textile floor coverings. Nevertheless, a smoother one Glossy floor often a little after vacuum cleaning dull. Furthermore, the bristle strips and / or rubber lips leave stripes on sensitive floors.

    Der Erfindung liegt die Aufgabe zugrunde, einen Saugkopf des eingangs beschriebenen Aufbaus so weiter auszubilden, dass auf glatten, glänzenden Böden ein besseres Reinigungsergebnis erzielbar ist.The invention has for its object a suction head to further develop the structure described at the beginning, that a better cleaning result on smooth, shiny floors is achievable.

    Zur Lösung dieser Aufgabe lehrt die Erfindung, dass die Trägerplatte eine Borstenleiste und ein Trag- und Dichtelement mit unterseitiger breiter Polierfläche aus einem weichen textilen Belag aufweist, wobei die Borstenleiste in Arbeitsrichtung vor dem Saugmund und das als Polierelement ausgebildete Trag- und Dichtelement in Arbeitsrichtung hinter dem Saugmund angeordnet ist. Geeignet ist vornehmlich ein Belag aus Filz, Plüschgewebe oder einem verdichteten Vliesstoff.To achieve this object, the invention teaches that Carrier plate a bristle strip and a support and sealing element with a wide polishing surface on the underside made of a soft Has textile covering, the bristle strip in Working direction in front of the suction mouth and as a polishing element trained support and sealing element in the working direction behind the suction mouth is arranged.

    Das an der Unterseite der Trägerplatte angeordnete erfindungsgemäße Element erfüllt mehrere Funktionen. Es nimmt die Normalkraft auf, die während des Saugvorganges von dem Benutzer sowie durch den Saugunterdruck auf das Gehäuseoberteil ausgeübt wird, und hält den Saugmund in einem vorgegebenen Abstand zum Boden. Es wirkt ferner als Dichtelement, das eine unkontrollierte Luftzufuhr insbesondere von hinten verhindert und damit den nötigen Saugunterdruck aufrechterhält. Schließlich ist es als Polierelement ausgelegt, welches den Glanz hochglänzender Böden auffrischt und Streifenbildungen, z.B. durch Gummiabrieb, mindert. In der Funktionsstellung "Trag- und Dichtelement eingefahren" hat das Element keinen Bodenkontakt, so dass sich die Schiebekraft des Saugkopfes beim Saugen auf textilen Böden nicht verändert und auch die Saugeigenschaften des Saugkopfes auf textilem Boden unverändert bleiben.The arranged according to the invention on the underside of the carrier plate Element fulfills several functions. It takes the normal force on the during the suction process User as well as by the suction vacuum on the upper part of the housing is exercised and keeps the suction mouth in one given distance to the ground. It also acts as a sealing element an uncontrolled air supply in particular prevented from behind and thus the necessary suction vacuum maintains. After all, it's designed as a polishing element which refreshes the shine of high-gloss floors and banding, e.g. due to rubber abrasion. In the functional position "support and sealing element retracted" the element has no ground contact, so that the Pushing force of the suction head when vacuuming on textile floors not changed and also the suction properties of the suction head remain unchanged on textile floor.

    Zweckmäßig erstreckt sich die Polierfläche in der Draufsicht zwischen einem keilförmig vorstehenden Abschnitt der Gleitsohle, welche die hintere Arbeitskante des Saugmundes darstellt, und dem Gehäuseoberteil.
