Attached to the PencilVac are four conical brush bars called Fluffycones. With two brush bars on each side, the front cone rotates in one direction while the rear brush goes the opposite way. The four bars jut out at the sides too; that way, it cleans in all directions with every pass on the floor. Each PencilVac comes with a rotating combination crevice tool for cleaning in between areas and conical hair screw tool for cleaning couches and mattresses.
