When I contacted a repair service far from my neighborhood to replace a broken belt in the detachable power nozzle i was told I would have to bring in the entire vacuum, cannister and all, as well! For a city dweller without a car that would have been very difficult.
Luckly I found the evacuum store website, called and was directed to the correct replacement belt. It was very inexpensive and easy to install. My 27 year old electrolux is working well. Thanks!
