Abstract

Die vorliegende Erfindung betrifft eine Bodenreinigungsmaschine (1) mit einem Fahrgestell (11) zur Bewegung über eine zu reinigende Oberfläche, mit einer Reinigungseinheit (9) zur Reinigung der zu reinigenden Oberfläche und mit einer Flüssigkeitsversorgungseinrichtung (35) , wobei die Reinigungseinheit an dem Fahrgestell gehaltert ist und mittels einer Hubvorrichtung zwischen einer angehobenen Ruheposition und einer abgesenkten Reinigungsposition bewegt werden kann, wobei die Flüssigkeitsversorgungseinrichtung eine Flüssigkeitszuführung (39) aufweist, die mit einem an der Reinigungseinheit angeordneten Auslass verbunden ist, und wobei zwischen der Flüssigkeitszuführung und dem Auslass ein Ventil (41) angeordnet ist, wobei ein Schließen des Ventils die Verbindung zwischen dem Auslass und der Flüssigkeitszuführung unterbricht, die dadurch gekennzeichnet ist, dass die Bodenreinigungsmaschine eine mit der Hubvorrichtung gekoppelte Betätigungseinrichtung (43) aufweist, die das Ventil schließt, wenn die Reinigungseinheit nicht in der Reinigungsposition ist.
