Floor Cleaning Machine
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.
1 - 40 . (canceled)
41 . A floor cleaning machine that is adapted and configured to be placed on a floor, the floor cleaning machine comprising:
a housing;
at least one pair of wheels mounted to the housing that are adapted and configured to support at least a portion of the housing above such a floor;
a handle on the housing that is configured and adapted to permit a person to control the movement of the housing relative to such a floor;
a first slit orifice that is adapted and configured to spray liquid in a first fan spray pattern against such a floor, the first fan spray pattern lying substantially within a first plane;
a second slit orifice that is adapted and configured to spray liquid in a second fan spray pattern and against such a floor, the second fan spray pattern lying substantially within a second plane; and,
the first and second planes being non-coplanar and oriented such that the first and second fan spray patterns do not intersect each other when liquid is being sprayed by both the first and second slit orifices against such a floor.
42 . The floor cleaning machine of claim 41 wherein the first and second slit orifices are positioned in spaced side-by-side positions on the housing bottom surface where the first and second spray patterns only partially overlap.
43 . The floor cleaning machine of claim 42 wherein the first and second slit orifices are positioned in spaced side-by-side positions on the housing bottom surface where a majority of the first and second spray patterns do not overlap.
