Santoemma NS400 Dual Powerbrush
NS400BR-Dual is a special wand with 2 counter rotating cylindrical brushes.
When using these wands, their two counter-rotating brushes allow for all the carpet fibres to be lifted and cleaned from all sides. This removes the dirt from the base of the fibres and even a very dirty carpet is left completely cleaned in a single pass, the carpet is left almost dry.
