I used to have Kenmore canister vacuums and loved them. Now I can't find a good canister vacuum without spending an awful lot of money. I have a Shark retractable bin that I bought a few years ago and I LOVE it. Unfortunately, Shark no longer publishes. This Kenmore is the third vacuum I have bought for another property and I have not liked any of them. What happened to the self-propelled power plants? I feel like my back is twisted trying to slide and pull this across the carpet. The head does not rotate, had to be rotated manually. The power head is heavy and HUGE! It is not suitable for places suitable for other vacuum cleaners. Doesn't stick well to hard floors. Not even birdseed. I don't know if the problem with the flex is that it's too short or too stiff, but it always seems to get in the way. Maybe I'm just too old to vacuum. :-)
