Abstract

Die Erfindung beschreibt einen Schmutzsauger mit Füllstandsmessung für Flüssigkeiten mit einem Differenzdrucksensor und einem daran angeschlossenen Füllstandsmessrohr, welches in den Innenraum des Schmutzbehälters bis in die Nähe des Bodens ragt. Um beim Übergang vom Saugen trockenen Staubes auf das Aufsaugen von Flüssigkeiten zu gewährleisten, dass das Füllstandsmessrohr nicht von Staubpartikeln verstopft ist, sieht die Erfindung vor, dass mindestens der untere Bereich des Füllstandsmessrohres von einem luftumspülten Schutzrohr umgeben ist.
