Unfortunate but true, the Eureka World Vac, as well as the similar Powerline Plus and Bravo! Series did have a number of reliability problems during the 1990s. In 1993, my mother bought a Eureka Bravo! The Boss model 9334AT, which constantly clogged, went through belts like crazy, and had its front wheels fall off every time the pile adjustment settting was changed. By 1996, she.became so disgusted with it that she replaced it with a Hoover Encore Supreme, which proved much more reliable. Furthermore, In Consumer Reports 1996 test of vacuum cleaners the ratings for the Eureka Powerline Plus and Bravo! Series uprights always included the remark, "durability is a worry," which was based not only on Consumers' Union's own inspections but also on letters submitted by readers about those models, which had previously been recommended by Consumer Reports.
Don't misunderstand me, they were handsomely styled machines and the ideas behind them were fine, it's just that the quality of the materials and workmanship left much to be desired.
