1. A vacuum cleaner comprising:
- a vacuum cleaner body;
a suction fan and motor operatively associated with the vacuum cleaner body;
at least one wheel comprising;
a wheel body having an axis of rotation;
a tread surface; and
a cushion layer radially interposed between the wheel body and the tread surface, the cushion layer comprising a resilient shell having a plurality of resilient cells therein, the shell and the plurality of cells having one or more gasses therein and being dimensioned to damp vibrations and impacts between the tread surface and a floor surface that the tread surface contacts as the wheel body rotates about the axis of rotation.

Abstract
A vacuum cleaner having a vacuum cleaner body, a suction fan and motor operatively associated with the vacuum cleaner body, and a wheel. The wheel has a wheel body having an axis of rotation, a tread surface, and a cushion layer radially interposed between the wheel body and the tread surface. The cushion layer includes a resilient shell having a plurality of resilient cells therein. The shell and the plurality of cells have one or more gasses in them, and are dimensioned to damp vibrations and impacts between the tread surface and a floor surface that the tread surface contacts as the wheel rotates about the axis of rotation.

16. A vacuum cleaner comprising:
-
a vacuum cleaner body; a suction fan and motor operatively associated with the vacuum cleaner body; a wheel comprising a plurality of discrete cells, the plurality of discrete cells being disposed around the circumference of the wheel, and each discrete cell having a flexible wall and a gas filled chamber surrounded by the flexible wall, wherein the flexible wall is dimensioned to damp vibrations and impacts between the tread surface and a floor surface upon which the tread surface moves.

19. A vacuum cleaner comprising:
-
a vacuum cleaner body; a suction fan and motor operatively associated with the vacuum cleaner body; a wheel comprising one or more cells adapted to support the vacuum cleaner body for rotation over a surface, the one or more cells having an internal volume and an air passage connecting the internal volume to an atmosphere surrounding the one or more cells, the one or more cells being formed by walls that are dimensioned to flex and expel air through the air passage under a force generated by a weight of the vacuum cleaner body against the surface to thereby resiliently support the vacuum cleaner body on the surface.
