Claims (32)

1. A cleaning machine adapted for the utilization of a working fluid to clean a wash load comprising:

a first enclosure comprising a wash unit, said wash unit comprising a wash chamber for containing the wash load located within said wash unit;

a second enclosure comprising a reclamation unit, said reclamation unit comprising a cross flow membrane filter;

conduits extending between the wash unit and said reclamation unit;

a control for operating said cleaning machine through a series of washing steps;

a clean tank; and

a permeate filter, wherein the permeate filter is disposed between the cross flow membrane filter and the clean tank.

2. A cleaning machine adapted for the utilization of a working fluid to clean a wash load comprising;

a first enclosure comprising a wash unit, said wash unit comprising a wash chamber for containing the wash load located within said wash unit;

a second enclosure comprising a reclamation unit, said reclamation unit comprising a cross flow membrane filter;

conduits extending between the wash unit and said reclamation unit;

a control for operating said cleaning machine through a series of washing steps;

a waste tank;

a clean tank; and

a dead end filter, wherein the dead end filter is disposed between the cross flow membrane filter and at least one of the following: the waste tank and the clean tank.

3. A fabric cleaning machine adapted for the utilization of a working fluid to clean a wash load, comprising:
