Query: electrolux cannister harmony

For the first 4 years I loved this vacuum cleaner, then the turbo brush broke. Not the brush itself but a plastic ring that keeps it attached to the hose. I replaced the brush with a regular brush and that one lasted about 6 times and is not powerful enough on the carpet. I now have to decide if I want to buy another turbo brush for $130 or so or if I want to invest in a new vacuum cleaner. If electrolux would have not have used the cheap plastic parts both brushes could have lasted a lot longer. I would not buy this brand again. The plastic parts are too flimsy and do not last.
