six year ago when I be shop for a vacuum with a hepa Filter , the overwhelming favorite among both consumer and consumer protection organization be the Eureka Boss SmartVac 4870DT .  Eureka 4870DT Upright Vacuum  my experience have be consistent with the great review that help I make my decision . pro : great suction , the rotary brush can be turn off for use on hardwood floor , and the hepa filter seem to really work ! con : heavier than most . I be not even consider replace this vacuum , but I be consider purchase another to keep upstairs !
