Heavy-duty carpet cleaners are usually employed by cleaning companies due to their highly effective use. In fact, they employ a higher pressure than hobby models, which ensures a more effective vapourisation of the liquid mixed with the detergent, resulting in deeper and faster cleaning.
The amount of air that flows out of the engine is also higher, and consequently more dust and dirt is trapped and removed.
Carpet cleaners are widely used by cleaning companies because they not only suck up dirt, in some cases they are also able to sanitise the fabric they are cleaning. In a single step, they can clean, vacuum and sanitise a surface, releasing a hot jet of steam that leaves no haloes or residue.
Carpet cleaners, or fabric washers, are designed with an injection/extraction function to ensure thorough cleaning of textile surfaces such as car interiors, upholstery and carpets.
They are equipped with a special liquid injector, a mixture of water and detergent contained in a special tank that performs the cleaning action on the surface.
Immediately after this step, there is a powerful and rapid suction of this liquid with subsequent drying.
In conclusion, the injection/suction system, consists of the double operation that carpet washing machines perform: cleaning and drying.
