Dirt Devil is a registered brand of TTI Floor Care North America. Under the name of Royal, P.A. Geier Company made the first vacuum cleaners in 1905 in Cleveland Ohio, being one of the world´s oldest vacuum cleaner manufacturing companies. Besides vacuum cleaners, the company produced mixers, hair dryers and washing machine units. Vacuum cleaners, though, remained the key product, as the company introduced the industry's first hand-held vac, the "Royal Prince," in 1937. Royal joined most manufacturing companies across the country and switched over to military production during World War II. In 1984, Royal introduced an innovative new product, the Dirt Devil® Hand Vac, which has grown to become Royal's signature product and the largest selling hand-held corded vacuum cleaner in the United States. Since its debut, more than 23 million Dirt Devil Hand Vacs have been sold. This success has opened the door for many new product introductions under the Dirt Devil brand name. Today, Royal (now TTI Floor Care North America) enjoys 98 percent brand name awareness in the Dirt Devil name and manufactures uprights, hand vacs, stick vacuums, canister vacs, and carpet shampooers. These products are now sold through major retailers nationwide and in Europe. TTI Floor Care North America's mission is to be a premier consumer products company, striving to recognize the needs of their customers and supply them with quality products that solve their cleaning problems.
