The BISSELL Little Green HydroSteam Pet 3605 is a compact spot cleaner for carpets, rugs and upholstery, built around steam-assisted washing for pet messes. It offers three modes: SteamWash for stubborn stains, Steam alone for freshening, and Wash for standard liquid cleaning. A dual-tank design keeps clean and dirty water apart, and BISSELL claims upholstery is touch-dry in about 30 minutes. It is a targeted stain tool rather than a whole-room carpet cleaner, so it suits pet owners and households with occasional spills more than anyone expecting deep cleaning of entire floors. Against the standard Little Green, the steam mode is the main step up; against full-size carpet extractors it trades coverage for portability and storage ease.
