I have had a Rainbow for nearly 30 years, that has ameliorated so many of our family's allergy problems. My elderly neighbor had an old Hoover that she was still using in the late 90s, purchased in the early 50s, when products were still made in America.
You are so right about “older” products lasting. My Mom had a fridge/freezer (in the garage) she got used in the 1950’s Darn thing was still running.. and WELL... when she passed in 2005.
Now you can buy great working vacuum a Wally World for $50 or less.
