The NS270 Brush is a special wand, with a cylindrical rotating brush. These can be used for cleaning carpet in combination with an injection-extraction machine. The mechanical brushing action allows the removal of dirt from the base of the carpet fibres. If there is residual dirt that is left on the base of the fibres, it resurfaces a few days after cleaning.
Even a very dirty carpet is left completely clean in a single pass. Minimal water is used to clean the carpet; therefore, the drying time is greatly reduced: the carpet can be dry in 1 hour.
