<p>The present application concerns the field of machines for floor treatment, such as cleaning and scrubbing, and in particular relates to the use of a vacuum squeegee assembly for collecting and lifting liquid from a floor surface during treatment. There is provided a squeegee assembly for collecting liquid from a floor surface, the assembly comprising an elongate roof portion provided with depending leading and trailing elongate squeegee blades, the blades and roof portion together defining an elongate liquid collection chamber when horizontally disposed on the floor surface, the chamber being provided with a vacuum vent so that the pressure in the chamber may be reduced so as to permit airflow entrainment and removal of liquid gathered by the squeegee blades in the chamber, characterised in that the chamber roof portion is upwardly inclined towards an end region thereof so that a floor to roof portion chamber height measured at an end region of the chamber is higher than a corresponding chamber height measured at a mid region of the chamber.</p> |
