Abstract
A floor cleaning machine has a housing and a movable hood that covers over vacuum and liquid hoses of the machine that are visible in prior art floor cleaning machines. The vacuum and liquid hoses are each pivotally connected to a wall of the machine housing and are also pivotally connected to a transparent dome provided on the hood. These connections reduce stresses on the hoses when the hood is moved and allow the dome to pivot relative to the hood. The floor cleaning machine also has a pair of slit orifices that eject fan spray patterns of cleaning liquid that are non-coplanar and do not intersect each other. Furthermore, the floor cleaning machine has an oscillating brush assembly that includes a brush that is replaceable without using tools. The brush height can be adjusted via an adjustment member provided on the oscillating portion of the assembly.
