Which Kenmore vacuum cleaners are made by

Which Kenmore vacuum cleaners are made by Panasonic? Are all of their direct drive machines made by Panasonic? We have a blue Hoover Windtunnel with the dirt sensor. It cleans well, but it is unbelievably noisy. I wondered if something was out of place and the brushes were hitting, but everything looks normal. We bought Kenmore models 36722 and 36724 and love them. I believe they were made by Panasonic. Our Kirby sits in the basement. Much heavier. These are quiet and clean well. I would like another, but not sure what the recent/current Kenmore models by Panasonic are. Do you?
