Kenmore recently introduced a new power nozzle with an anti-tangle brush roll with their latest version of the 600 Series canister, the BC4030. The nozzle looked neat and I have an earlier flavor of the 600 Series, the purple 81614 so I stalked eBay until one turned up and bought it. Then I tried to find parts for it but no luck. I ended up calling Kenmore's vacuum hotline ( there is such a thing ! ) and spoke to a very nice lady about finding things like brush rolls, belts and the hose that runs up the inside of the neck that you know is going to split open eventually. No service parts of any kind available. According to this nice lady Kenmore has come to the conclusion that people don't know how to fix anything and when they try they end up making things worse. So instead you buy a whole new power nozzle for $86. Ok, so yeah that is cheaper than the price Miele charges for an SEB236 brush roll ( $95 and nobody sells it at a discount ) but how wasteful ! Throw away an otherwise serviceable power nozzle because the brush roll wore out. I tried e-mailing Suzhou Cleva Electric Appliance Co Ltd in China, the company that makes it, seeing if I could buy parts directly from them but never heard back. Calling Cleva North America got me nowhere.
So there you are, Kenmore thinks customers are too ham handed to fix their own stuff. Ain't life grand : /
