The Dyson Hair Screw Tool (971426-01) is a specialized turbo brush designed to efficiently clear hair and pet fur from hard floors and upholstered surfaces. Its grey finish blends seamlessly with the vacuum's aesthetic, while the internal mechanism focuses on solving the common problem of brush tangles. At the heart of this tool is a conical brush bar that uses a spiral action to wind hair off the surface and direct it straight into the bin. This design ensures that you spend less time manually cutting hair away from the bristles, making it a practical choice for households with shedding pets. It is compatible with a wide range of cordless models, including the Dyson V15 Detect, V11, Cyclone V10, V8, and Outsize.
