Abstract
Abstract An improved cleaning mechanism for removing contaminants from generally non-porous surfaces. A sponge-like member surrounds a hollow perforated core. Sprayers, internal to the core, spray liquids under pressure to aid in removing contaminants from the sponge-like member. A pinch roll squeezes the sponge-like member against the core at a position where an internal baffle strip contacts the core. This seals the squeezed sponge-like member at the core preventing liquids and contaminants from passing the seal barrier formed.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
80 words
Apparatus for cleaning a surface including a perforated hollow core means mounted for rotation; a porous, sponge-like member for interfacing with the surface to be cleaned at a first position, said sponge-like member being mounted externally on said perforated core means; means internal to said core means for applying liquid therethrough to said sponge-like member; a pinch member for squeezing the sponge-like member against the perforated core means at a second position along its surface removed from the first position.
Claim 2
Dependent Claim
80 words
Apparatus for cleaning a surface including a perforated hollow core means mounted for rotation; a porous, sponge-like member for interfacing with the surface to be cleaned at a first position, said sponge-like member being mounted externally on said perforated core means; means internal to said core means for applying liquid therethrough to said sponge-like member; a pinch member for squeezing the sponge-like member against the perforated core means at a second position along its surface removed from the first position.
Claim 3
Dependent Claim
85 words
Apparatus for cleaning a surface including a perforated hollow core means mounted for rotation; a sponge-like member for interfacing with the surface to be cleaned at a first position, said sponge-like member being mounted externally on said perforated core means; means internal to said core means for applying liquids therethrough to said sponge-like member including spray headers and directing nozzles; a pinch member for squeezing the sponge-like member against the perforated core means at a second position along its surface removed from the first position.
Claim 4
Dependent Claim
85 words
Apparatus for cleaning a surface including a perforated hollow core means mounted for rotation; a sponge-like member for interfacing with the surface to be cleaned at a first position, said sponge-like member being mounted externally on said perforated core means; means internal to said core means for applying liquids therethrough to said sponge-like member including spray headers and directing nozzles; a pinch member for squeezing the sponge-like member against the perforated core means at a second position along its surface removed from the first position.
Claim 5
Dependent Claim
