Carpet cleaning machines work basically on two types of carpet cleaning systems; the dry system and the wet system. The wet system requires water and the dry system makes use of special extraction machines.

Wet carpet cleaning machines are the most commonly used machines at home. These machines inject a cleaning solution onto the carpet which then penetrates the fibers. This removes oil and grease deposits and causes the embedded soils to loosen as these are immediately extracted by extremely powerful vacuum motors. You must make sure that when you use wet carpet cleaning machines, carpets must not be over wetted as this may cause shrinkage or discoloration of the carpet.

One of the most common machines that make use of wet cleaning method is an extraction machine. An extraction machine makes use of detergent solution for cleaning. This solution is forced onto the carpet by a pump and penetrates into the fibers of the carpet. Then the high powered motors suck it out. In order to break the dirt particles down, a heater is also installed either internally or externally to the machine. They clean better than the other machines. They have built in brushes that scrub the carpet too while cleaning. A few extractors are also equipped with handle telescopes. These are popularly known as swingers and allow the user to stand upright in a comfortable position. They are extremely useful in places which witness high foot traffic and hence get heavily soiled. These are equipped with thick steel rotary cleaning heads that have around three vacuum extraction slots along with three spray jets for better and faster results.

Dry cleaning machine is another type of carpet cleaning machine used commonly. This machine makes use of a dry absorbent chemical that is spread onto the carpet before being vacuumed. The dirt is then sucked in by extremely powerful vacuum motors, thereby leaving the carpet clean and dry. No matter what system you choose, it must be safe, must not involve any sort of risk, easy to use, tough, and unbreakable, must have a powerful suction system.

The two most common carpet cleaning equipment available in the market that make use of dry cleaning mechanism are Dirt Invader and a vacuum carpet cleaner. A Dirt Invader is a lightweight yet strong machine that is equipped with a circular motion vacuum tank that can extract even the most stubborn of dirt particles through the dry system mechanism. It has been designed for daily use is highly effective at public places which witness greater foot traffic. Vacuum cleaners are extremely good for use on staircases, floors made of hardwood, wall to wall carpets, drapes etc. they are equipped with long attachments to reach the farthest of corners.

Purchasing a carpet cleaning machine makes the most economic sense when your carpet is light in color and your home is populated with kids and/or pets as you would be required to clean the carpet more often. This will save you a lot of money which you will have to shell out in order to seek professional service.
