I have a henry hound vacumm. it has the powerbrush head but in the last 2 years i have had to have the hose in the powerbrush head replaced as it keeps splitting. Has anyone had the same problem?? It is not expensive to repair but inconvenient. I have looked for a spare head but i have only found one website that sells the accesories for the Henry hound and it would cost me £70. Does anyone know of anywhere that i can order a part from and perhaps not at that cost??
