Cleaners who graduate from Host School training programs, own Host dry extraction cleaning equipment and clean no less than 50 percent of their jobs with that system qualify to join the Host PCA Professional Cleaner Association.

Founded in 1988, the HPCA offers members benefits such as a liability insurance program, yellow-pages listings as a "Host Authorized Cleaner," sales on select parts and use of association logos. Technical support services include videos, newsletters, a toll-free help line and tuition discounts on additional Host School training.
