Carpet cleaners, as is evident from name, are used to clean carpets, mats, and upholstery. These machines, also known as carpet shampooers and carpet extractors, can be broadly classified into two major categories: heated and non-heated equipment.
Non-heated carpet cleaning machines utilize inlet temperatures to clean carpets. These systems are ideal for low-traffic commercial areas or for cleaning heat-sensitive carpet fibers. Heated units, on the other hand, use steam temperatures up to 210°F to more readily soften and dissolve hardened stains, allowing for faster, more effective cleaning. Despite the differences between these two types of machines, the operation is the same, as discussed below.
The Cleaning Process
One can divide the cleaning process with carpet cleaner machine into five stages, starting with vacuuming loose dust from the surface.
Second, the operator must pre-spray the carpet with a cleaning solution. Green chemicals are desirable as they clean without releasing toxins that harm the environment, the user, and the carpet itself. Then, the user infuses water or a mixture of water and the cleaning agent into the carpet. The pressure and temperature levels of the output of carpet cleaners can be varied, depending upon the hardness of the surface and difficulty of the cleaning job.
Let the mixture remain on the surface for about 15 to 20 minutes. The idea is to let the cleaning solution penetrate inside the carpet’s surface and weaken the bond between the dirt and the carpet fibers.
The third stage of the process involves agitating the surface with a carpet cleaning wand. Top suppliers offer a variety of additional wands for cleaning upholstery, stairs, and even hard surfaces. Walk behind units are also available, where the operator walks behind the machine as it agitates the surface.
The final stage of the cleaning process involves extracting the dirt-laden water and all residues of cleaning solution from the surface of the carpet using the carpet wand. The extracted residues are stored in a recovery tank.
One should not confuse the solution tank with the recovery tank. Carpet cleaning systems usually contain two tanks. The first is the solution tank, where a mixture of water and cleaning agent is stored. The second is the recovery tank in which the extracted residues of dirt and cleaning agents are kept.
The vacuum attached with the surface is an important specification for the carpet upholstery cleaning process. A vital specification of the vacuum is its airflow, which is a measure of its absorption capability. It is expressed in cubic feet per minute (cfm). Normally, the airflow of the vacuum attached with carpet cleaners range from 100 cfm to 200 cfm.
Given the number of different temperature and extraction specifications available on today's systems, the best choice is to consult a reputable supplier who will guide you to find the right carpet cleaning equipment and machine for your application.
