The machine consists of 2 modules. On one side there is the Dust Module which has some rotatory crosses which beat the carpet in order to remove its dust. The carpet goes into and comes out of the machine through the same place. In this way you can save space and just one person can do the work. When the carpet comes out of the machine it rolls up on its own. On the other side there is the Vacuum Module, which picks up the dust, filters it and stores it. Dust is removed perfectly with this system, the most efective available.    Maximum width of the carpet: 3.2 metres.    Speed of advance: from 0.5 to 2.2 metres/minute.    Mod.
