Evidence Supporting Use
vacuum airflow and crevice agitation remain controlled while surfactant wetting produces the expected material response.
solvent action, towel transfer capacity, and extractor solution delivery can be observed independently without masking residue or an unstable finish.
Evidence Requiring a Stop
Stop when extractor recovery airflow, wick-back control, or ventilation exchange cannot be verified within the supported process window.
Unknown material, uncontrolled drying temperature, incompatible odor-source access, or failed function-stage gate requires another method, location, repair, or qualified service.
