I will say this: dyson changed the vacuum industry. Prior to the Dysons... my vacuums lasted one year to 18 months. Name a brand, name a design... planned to break/stop working. I was never hard on them or rough either. I heard about Dyson from a gal pal and purchased one (granted the price was high... but so is replacing one every year). That lasted about 15 years. During that time, vacuum companies made their vacuums with “no loss of suction “ and longer lasting.
You know, Hoover got a bad rap for causing the Depression and all, but the vacuum cleaner he made was one of the best at the time.
His dam is still working, so he did some things “right”.
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.
I’ve got a thirty year old Electrolux that’s going strong.
I’ve never had ANY vacuum cleaner quit working. You have to do normal maintenance and belt replacement, of course.
