Verdict

The Polti StainOver SC20 is a four-in-one cleaner for carpets, upholstery and other fabrics that combines hot- or cold-water washing, extraction and Vaporetto steam through its SteamActive system. It is intended for stubborn stains, pet-related messes and vehicle interiors, and is claimed to remove up to 99.999% of germs, bacteria and fungi without detergent. An LED display, voice guidance in seven languages, four steering wheels, removable tanks and nine accessories make the machine versatile and comparatively easy to operate. Its main compromises are the storage space required by the unit and manually wound cable, plus the need for frequent tank refilling and emptying during intensive cleaning sessions.
