Version with cylindrical brushes
The cylindrical brush head consists of two counter-rotating cylindrical brushes that not only scrub but also make a light sweeping action. The sweeping action removes small, solid, non-adherent residue and collects it in a drawer installed at the rear of the brush head, which is removable for emptying. This type of brush head is recommended for hard floors (even structured, uneven or non-slip). The bristles clean deep down, guaranteeing optimum results even where there are wide gaps. Given the high specific pressure and the notable rotation speed, it's more suited to resistant floors not protected with a polymer film (wax). The counter-rotating movement keeps the detergent solution inside the scrubbing area, increasing efficacy yet ensuring low water consumption.
