Abstract

Die Erfindung betrifft ein Flächenreinigungsgerät (210) mit einem Gehäuse (212), in dem ein Saugaggregat (306) angeordnet ist, und mit einer mit dem Saugaggregat (306) in Strömungsverbindung stehenden Saugdüse (216) zum Absaugen eines Flüssigkeits-Luftgemisches, und mit einer Abscheideeinrichtung (258) zum Abscheiden von Flüssigkeit aus dem abgesaugten Flüssigkeits-Luftgemisch, und mit einem Flüssigkeitstank (218) zur Aufnahme der abgeschiedenen Flüssigkeit, wobei der Flüssigkeitstank (218) am Gehäuse (212) lösbar gehalten und über eine Tankentleerungsöffnung (322) entleerbar ist. Um den Flüssigkeitstank (218) auf einfache Weise entleeren zu können, ohne dass die Gefahr besteht, dass bei einem anschließenden Betrieb des Flächenreinigungsgeräts (210) Flüssigkeit aus dem Flüssigkeitstank (218) entweicht, ist die Tankentleerungsöffnung (322) von einer Schließwand (254) des Gehäuses (212) dicht verschließbar und durch Lösen des Flüssigkeitstanks (218) vom Gehäuse (212) frei zugänglich, wobei die Schließwand (254) ein Schließglied (278) aufweist, und wobei der Flüssigkeitstank (218) ein Tankgehäuse (310) und eine Befüllungseinrichtung (316) aufweist, die die Tankentleerungsöffnung (322) aufweist.The invention relates to a surface cleaning device (210) with a housing (212) in which a suction unit (306) is arranged, and with a suction nozzle (216) which is flow-connected to the suction unit (306) for sucking off a liquid-air mixture, and with a separating device (258) for separating liquid from the suctioned liquid-air mixture, and with a liquid tank (218) for receiving the separated liquid, the liquid tank (218) being detachably held on the housing (212) and being able to be emptied via a tank emptying opening (322). is. In order to be able to empty the liquid tank (218) in a simple manner without the risk of liquid escaping from the liquid tank (218) during subsequent operation of the surface cleaning device (210), the tank emptying opening (322) is surrounded by a closing wall (254) of the housing (212) and freely accessible by detaching the liquid tank (218) from the housing (212), the closing wall (254) having a closing element (278), and the liquid tank (218) having a tank housing (310) and a Filling device (316) having the tank emptying opening (322).
