The high-torque floor nozzle is not explicitly mentioned as compatible with the Dyson V11 Fluffy. The electric brush with soft roller (Fluffy floor nozzle), which was specially developed for hard floors and is compatible with Dyson V8, V10 and V11 hoovers, is recommended for the V11 Fluffy. The High Torque Floor Nozzle is more commonly used on other models such as the Dyson V15. Therefore, the high-torque floor nozzle probably does not work optimally or is not intended for the V11 Fluffy. The suitable floor nozzle for the V11 Fluffy is the soft-roll Fluffy floor nozzle.
