We have a Kenmore canister vacuum cleaner which is more than 10 years old. This attachment was lost. I was afraid that the new one wasn't going to fit my vacuum cleaner. It did perfectly and it arrived the day after I ordered it.
This newer model nozzle is junk, pure junk. The swivel piece fell apart from the floor piece on day one, and continued daily from then. I luckily kept one from a 10 year old model - it still works perfectly WITHOUT coming apart. This should be redesigned and also made large - much larger.
If you have a lot of hard floors you really want to buy this extra nozzle for your canister vacuum. Yes, you can vacuum hard floors by turning off the brush on the regular head, but it's heavy and unwieldy. I just wish this nozzle was a bit wider so it would cover more territory.
