If carpets are cleaned on a regular basis and do not get particularly extremely dirty, then a non-heated carpet washer machine might be adequate. This type of a portable carpet cleaner is not very expensive, as it does not have a heating device. This machine can also use hot water for washing rugs and carpets.
Most contractors prefer a low flow portable carpet cleaner, as it is more water efficient. This translates into greater savings, and eventually, greater productivity. The carpet washed with a low flow machine dries faster, and is less vulnerable to mold formation.
These high pressure levels in commercial carpet washer systems are an added advantage. Such powerful machines offer faster cleaning, as compared to the machines used for domestic carpet cleaning.
Moreover, a portable carpet shampooer machines should not only clean fast, though also clean efficiently, removing grease, dirt, odors, and stains. Do a thorough research before buying any carpet cleaning equipment.
