how old is the system, our systems are originally facelifts, still going well after over 10 years, obviously changed filters / etc, but still going, liked the old poles, weve got a 72 ft facelift, some 18ft and 35ft poles, all been good poles, cant speak much of new poles yet as only got one last week and i broke one of the clips so not used it much yet, when i did use it it seems easy to use,(25ft)
