Dense Foam extractors

In some particular areas, such as carpet or rugs near room entrance, or when the application requires an immediate availability of the surface after cleaning, carpet and upholstery c an be cleaned with foam, instead of a solution of water and chemical. Thanks to the special Santoemma DENSE FOAM technology, available on some models of the range, it is possible to clean such surfaces with foam. Dense foam is spread on the surfaces, brushed and vacuumed after some seconds. Unlike a normal solution of water and detergent, dense foam does not penetrate in the depth of carpet, but acts only on the superficial layer, just where most of the dirt lies. Dense Foam extraction system allows you to get an excellent maintenance cleaning and an extremely short drying time.

In order to obtain the special dense foam, the chemical solution is mixed with compressed air, obtained by a dedicated air compressor in the machine. The quality of the foam is therefore much better than the “liquid foam” of some machines on the market, which have no compressor. On the other hand, thanks to its optimal density, dense foam does not remain only on the surface (as it happens with "dry foam”), but it penetrates for few millimetres in the superficial layer where the dirt lies.
