1. A vacuum cleaning apparatus comprising:
- a vacuum cleaner base including a source of suction and front and rear wheels for wheeling the base across a floor;
a nozzle assembly attached to and supported by the base, the nozzle assembly including a suction inlet and a sheet-pressing surface that are located in front of the front wheels; and
a disposable sheet configured to be removably attached to the nozzle assembly such that, as the base is wheeled across the floor, the sheet-pressing surface presses the sheet against the floor to dislodge dirt from the floor, and the suction draws the dirt from the floor to and through the suction inlet.

Abstract
A vacuum cleaner base includes a source of suction and front wheels and rear wheels for wheeling the base across a floor. A nozzle assembly is attached to and supported by the base. The nozzle assembly includes a suction inlet and a sheet-pressing surface that are located in front of the front wheels. A disposable sheet is configured to be removably attached to the nozzle assembly such that, as the base is wheeled across the floor, the sheet-pressing surface presses the sheet against the floor to dislodge dirt from the floor, and the suction draws the dirt from the floor through the suction inlet.

12. A vacuum cleaning apparatus comprising:
-
a nozzle configured to be connected to a source of suction, the nozzle having a suction inlet and a brushroll extending through the suction inlet and configured to rotate against a floor to dislodge dirt from the floor; a bracket removably attached to the nozzle and having a sheet-pressing surface, a portion of which located directly below the brushroll; and a disposable sheet having an opening and configured to be removably attached to the nozzle and configured such that, as the nozzle is moved along a floor, the sheet-pressing surface presses the sheet against the floor to dislodge dirt from the floor as the suction draws the dirt from the floor through the sheet'"'"'s opening and the nozzle'"'"'s suction inlet. - View Dependent Claims (13, 14)

15. A vacuum cleaning apparatus comprising:
-
a nozzle assembly configured to be connected to a source of suction, the nozzle assembly having front and rear suction inlets and a sheet-pressing surface located between the inlet openings; and a disposable sheet having front and rear airflow openings, and configured to be removably attached to the nozzle assembly with the front and rear airflow openings of the sheet respectively aligned with the front and rear suction inlets of the nozzle assembly; and configured such that, as the nozzle assembly is moved along a floor, the sheet-pressing surface presses the sheet against the floor to dislodge dirt from the floor and the suction draws the dirt from the floor through the sheet'"'"'s front and rear airflow openings and the nozzle assembly'"'"'s front and rear airflow inlets. - View Dependent Claims (16, 17, 18)

19. A vacuum cleaning apparatus comprising:
-
a nozzle assembly having opposite front and rear side edges and opposite first and second end edges, and configured to be connected to a source of suction, the nozzle assembly having front and rear sheet-pressing surfaces and an airflow inlet located between the sheet-pressing surfaces; and a disposable sheet having an airflow opening, configured to be removably attached to the nozzle assembly in a mounted position in which the airflow opening is located between the front and rear sheet-pressing surfaces and, under the first end edge, an end opening is vertically bounded by the nozzle assembly and the sheet and horizontally bounded by the front and rear scrubbers; configured such that, as the nozzle assembly is moved along a floor, the sheet-pressing surfaces press the sheet against the floor to dislodge dirt from the floor, and the suction draws air through the end opening to the sheet'"'"'s airflow opening for the air to carry the dirt from the floor upward through the sheet'"'"'s airflow opening to and through the nozzle assembly'"'"'s airflow inlet. - View Dependent Claims (20)
