Whether a carpet cleaning machine removes stains and odors from pets depends largely on whether the padding underneath the carpet is contaminated. However, in exchange for a smaller capacity, the machine is more compact and easier to store than many other carpet cleaners. Many of the most popular models use a half gallon or one-gallon clean water tank and combine it with a dirty water tank for cleaner, more efficient carpets. The Good Housekeeping Institute's appliance and cleaning product laboratory evaluates carpet cleaning machines to determine how well they clean previously soiled and dirty white carpet test panels, industry standard.
If you're frequently left with spills or stains, you'll likely appreciate a carpet cleaner that includes a tool specifically designed to treat tough stains with increased agitation. Cleaning the carpet means ending up with a tank full of dirty water, and while vertical carpet cleaners are generally more difficult to clean than portable cleaners, Bissell tried to make the process as simple as possible. A carpet cleaner is the best way to remove dirt, stains and odors embedded in any wall-to-wall carpet and large area carpets. They run a carpet cleaner over the carpet for four wetting cycles and four drying cycles to simulate a consumer cleaning a particularly dirty area of a carpet with heavy traffic.
Many come with hoses and mini-nozzles to more easily clean small areas, such as upholstery and stairs, and all have two tanks, one that is filled with clean water and detergent solution and another for the dirty water that is extracted from the carpet. If you're looking to invest in a professional quality carpet cleaner for your home or work space, this is the one for you. The Bissell Big Green PET PRO carpet cleaner is a derivative of the manufacturer's commercial Big Green cleaning machine that is specifically designed to treat pet stains, including stain odors.
