Carpet Extractor

Carpet extractor systems, recovery metrics, drying risks and buyer verification

This technical profile separates documented spray-extraction functions and model specifications from WCB procurement assessment so buyers can compare carpet extractors within compatible operating and reporting boundaries.

Included
  • Commercial self-contained carpet extractors
  • Commercial tank extractors used with approved carpet wands or powered tools
Excluded
  • Dry compound or encapsulation-only systems
  • Domestic carpet cleaners
  • Hard-floor scrubbers and unattended flood-water recovery
