Carpet cleaning machines require a 120-volt outlet (the standard three-prong outlets that are found throughout the home). Most carpet clearing machines come equipped with a power cord over 20 feet long to enable them to reach to every corner of a standard room without having to change outlets.
Carpet cleaning machines come from a variety of manufacturers, each one specializing at different tasks. For example, the top-rated Hoover Power Scrub excels at cleaning large areas very quickly. However, if only a small spot needs cleaning, the Bissell Spot Clean may be a better option.
One of the most popular brands of carpet cleaners is Rug Doctor. Rug Doctor cleaners are available for rent at many home goods stores, such as Wal-Mart, Home Depot and Big Lots.
