There were two version for brush,Vacuum cleaner floor brush and carpet sweeper.
Generally speaking, the soft velvet roller brush suction head is suitable for the cleaning of hard floors, because ceramic tiles or wood floors are flat and hard materials. This flexible brush head can play a better role in fitting. In addition, there is a direct drive suction head that is suitable for carpets. The spiral hard brush: after friction between the hard brush and the velvet material of the carpet, it is easier to hook up the garbage hidden in the deep layer of the carpet, I don't recommend using the hard brush directly on the wooden floor. The reason is very simple. When the hard brush rotates at a high speed, it is like a hard brush rubbing the wooden floor repeatedly, which will scratch and wear the wooden floor to a certain extent.so best choose is important.
