After about 12 years the front of my dc07 wouldn't make contact with the surface I was trying to vacuum. I found that the front was raised and not touching the ground at all. As a temporary solution I attached a 5lb weight to the front and was able to get a proper seal on the floor to create suction. At the same time, I only used my wireless Dyson, but I never managed to vacuum the whole house at once. Upon further investigating the cause, I found that this hose had become inflexible, not allowing the vacuum to tilt and maintain ground contact. It was a cheap and easy solution that I should have checked out two years ago.
