Prevents hair from wrapping around the main brush shaft, reducing brush tangles and cutting the time you spend on maintenance. Maintains stable cleaning performance across different floor types—works reliably in mixed environments such as carpets, hard floors, and rugs. Made from environmentally friendly material that releases no odor during use, so it stays neutral in scent during long cleaning cycles. Precise openhole, lowprofile design keeps sensor components unobstructed, preserving the vacuum's detection and navigation functions. Minimal interference with brush action and suction—designed to protect the brush shaft without compromising overall cleaning efficiency. Practical applications Pet homes: reduces hair buildup on the main brush shaft from shedding dogs and cats, lowering how often you need to cut or remove wrapped hair. Apartments and bedrooms: helps manage long human hair and lint on rugs and lowpile carpet, simplifying routine upkeep. Kitchens and entryways: performs consistently on hard floors and mixed debris zones where hair, dust, and small particles collect. What to expect Clear functional benefit: less frequent brush cleaning and fewer interruptions for manual detangling. Reliable compatibility with standard main brush assemblies and sensor layouts where an openhole protector is required. Durable, odorless material suitable for everyday household vacuuming needs.
