Hoover Concept One and Concept Two Vacuum Cleaner Service Instructions
1.0
These service instructions take you through complete disassembly of the cleaner, including the motor for both power drive and non-power drive models. If you are looking to keep your Concept in top-shape, or specifically fix something that's broken, these are a must! While not as easy to service as a basic Convertible; the Concept really isn't too bad to work on, these instructions will surely help the novice.
Aligning with its 70th anniversary, in 1978 Hoover introduced the Concept One into their product-line, replacing the 15-year old Dial-A-Matic as the new 'A-Line' of cleaners. Hoover went back to the dirty-air design, and built, arguably, one of the best carpet-cleaning vacuum cleaners ever made. The Concept one came in both self-propelled and non-self propelled models. The Quadraflex Agitator was introduced with the Concept, and the cord-winder came back to an upright after a brief appearance on a Convertible in the early 70s. A few years later, Hoover added a 'Dustbuster' type vacuum to the front of Concept, and the Concept Two was born; also in self-propelled and non-self propelled models. The Concept had a run of about 16 years, give or take - ending as the 'PowerMax' (PowerMax service instructions are not specifically included within these particular service instructions, but the PowerMax is very similar to the Concept in most ways).
