An extractor cleaning machine includes a supply tank assembly having a first tank and a second tank. The first tank is in fluid communication with a distributor. The first tank has a rigid body defining a first storage chamber for storing a first cleaning fluid and supplying the first cleaning fluid to the distributor. The second tank is positioned within the first storage chamber of the first tank in fluid communication with the distributor. The second tank has a rigid body defining a second storage chamber for receiving a second cleaning fluid and supplying the second cleaning fluid to the distributor. At least a portion of the rigid body of the second tank defines a boundary of the first storage chamber to separate the first cleaning fluid and the second cleaning fluid.
