Dirt Devil is an American vacuum cleaner and floor care company. It is the brand and subsidiary of Techtronic Industries, and its corporate legal name is now TTI Floor Care North America. The company was founded in 1905 in Cleveland, Ohio by Philip Geier as "P. A. Geier Co". It was renamed to "Royal Appliance Manufacturing Co" in 1953. Originally, the company made vacuum cleaners with aluminum casings. They also manufactured mixers, hair dryers, and washing machines. The "dirty air" design was used for the vacuum cleaners, with the electric motor positioned horizontally, the turbine blades at the front and a downward facing nozzle in contact with the cleaning surface. The dirt was collected at the vacuum exhaust in a heavy cloth bag, which needed to be shaken to remove the collected dirt on a regular basis. More information...
