Carpet Washers Carpet washers clean your carpets using a detergent cleaning solution. Using a carpet washer helps to reduce the appearance of stains and break down ground-in and embedded dirt that builds up in the carpet pile. Using a carpet washer can leave your carpets up to ten times cleaner than vacuuming, and can be dry enough to walk on in two to three hours. Carpet washers can be large full size or portable, allowing you to choose a carpet washer to suit your needs. Full size cleaners are suitable for cleaning larger areas such as rooms, hallways and rugs. Portable deep cleaners are smaller, and are adept at cleaning small stains and spills, ideal for those with small children or pets.
