A filter for a carpet cleaning device and method for using therefor includes a casing and a partition that extends into the casing to define a primary chamber and a secondary chamber within the casing. A main siphon with an inverted U-shape is mounted in the partition. One end of the siphon extends into the primary chamber while the other end of the siphon extends into the secondary chamber. An auxiliary siphon is located within the secondary chamber, and a pump is attached in fluid communication with the auxiliary siphon. During operation, a wastewater/debris stream is transported into the filter. The stream collects in the primary chamber and establishes a primary fluid level therein. As the primary fluid level rises, carpet fibers and other insoluble debris settle in the primary chamber. Once the primary fluid level is even with the siphon, wastewater fluid is transported from the primary chamber to the secondary chamber and establishes a secondary fluid level therein. As the secondary fluid level rises, any remaining debris settles in the secondary level. Once the secondary fluid level reaches a predetermined level, the pump is activated to transport wastewater from the secondary chamber for further disposal.
