Abstract
Abstract A mop assembly is provided for the continuous application of wax and cleaning fluids which utilizes a detachable, disposable plenum incorporated into a disposable sponge mop. The disposable plenum has a plurality of substantially uniformly-spaced openings which provide for a substantially uniform distribution of fluid entering into the sponge. The disposable mop also has a substantially impermeable backing layer which shields the mop head and other non-disposable parts from wax, cleaning fluid, and residue present in the sponge. The disposable mop eliminates the problems associated with clogging of the openings in the non-disposable plenums currently in use, and substantially reduces the amount and frequency of required cleaning of the mop head and other non-disposable parts.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
129 words
A disposable mop comprising: a first layer comprising a sponge material, a second layer comprising a material which is substantially impermeable to waxes and cleaning fluids; a disposable plenum between the first and second layers having a plurality of openings for distributing fluid into the sponge material; a backing layer adjacent to the substantially impermeable layer; and a layer positioned such that the sponge material layer is between the cloth material layer and the plenum of cloth material adjacent to the sponge material layer; the layers being joined at respective edges of the layers such that the substantially impermeable layer, the plenum and the sponge material layer are substantially enclosed between the backing layer, said layers and said plenum forming a unitary disposable assembly and the cloth material layer.
Claim 2
Dependent Claim
129 words
A disposable mop comprising: a first layer comprising a sponge material, a second layer comprising a material which is substantially impermeable to waxes and cleaning fluids; a disposable plenum between the first and second layers having a plurality of openings for distributing fluid into the sponge material; a backing layer adjacent to the substantially impermeable layer; and a layer positioned such that the sponge material layer is between the cloth material layer and the plenum of cloth material adjacent to the sponge material layer; the layers being joined at respective edges of the layers such that the substantially impermeable layer, the plenum and the sponge material layer are substantially enclosed between the backing layer, said layers and said plenum forming a unitary disposable assembly and the cloth material layer.
