Vacuum Cleaners Discussions

Ignoring my other post about canisters, I am looking for a Christmas gift for Mom.. She is getting older now and is having trouble in the strength department... She still lugs her Kirby g3 around the house, but is wanting something for the downstairs bedrooms... After listening to her describe what she hates about all of the vacuums I have brought to her here is what I need to find:

A bypass upright with the motor in the head and not the neck, no on board attachments and has the ability to go under beds..

Does such an animal exist? I'd give her my oreck that I have but the brush roll is so soft compared to the others that it really won't separate the nap and clean the floors...

Thanks in advanced!

Curious if you considered any canister vacuums? All she would have to handle is the weight of the wand and a powered floor brush, which is going to be less than that of any upright. The primary weight sits on the floor and rolls around on wheels. Just a thought.
