Gear Score Methodology
PetPal Gear Score
Best Carpet Extractors for Pet Urine and Stains (2026)
Editorial synthesis of the IICRC's published consumer guidance on carpet care and animal stains (including the two ANSI/IICRC S100 passages the IICRC quotes in its own consumer tip sheet), Humane World for Animals and ASPCA pet-cleanup protocols, VCA Animal Hospitals house-soiling guidance, and Asthma and Allergy Foundation of America allergen guidance — paired with manufacturer specification pages fetched directly from Bissell, Bissell BigGreen Commercial, and Hoover, and live listing data pulled per product through the Amazon Creators API. PetPalHQ does not operate a carpet-cleaning test lab, and no score below is a measurement.
