High Elasticity and Flexibility Material: Made of high-quality flexible raw materials, it can bend and twist freely without easily breaking. Daily cleaning, turning corners, and maneuvering around furniture all allow smooth stretching without sticking. Freely Expandable Design: Features good stretch and rebound performance, allowing you to extend or shorten as needed, and flexibly adapt for cleaning high areas, low spaces, and distant spots. Sealed Leak-Proof Structure: Both ends fit tightly with good sealing, preventing air leakage during vacuuming and maintaining suction power, ensuring stable and efficient cleaning performance. Durable Abrasion-Resistant Outer Layer: The outer layer is thickened and treated for wear resistance, resistant to friction and pulling, and not easily scratched or damaged, making it more durable for long-term use on floors and corners at home. 2.5m Vacuum Cleaner Hose，Compatible For Numatic，Compatible For Henry，HVR200 NVH180 For NBV 190-1 Vacuum Cleaner Hose Tube Vacuum Hose Attachment, Manufacturer: HIZON
