The brush set for Dyson PencilVac Fluffycones and Dyson PencilVac SV50 vacuum cleaners includes two of these soft rollers.
These conical soft brushes are designed to easily pick up dirt and hair from hard floors without tangling. The vacuum's brushes should be replaced when the unit no longer collects dirt as effectively as it used to.
Please follow your vacuum cleaner's user manual when replacing the brushes and rollers.
