Genuine Flomax hose suits all models of Henry, Hetty, James and Junior vacuums. You must use this version of hose to suit the latest low power consumption (low wattage can be identified by no 2 speed motor switch on machine) range of vacuum cleaners. Using the older non tapered (flomax) hose will result in low or no suction on the latest vacuums. Hose length 2.2m
