Abstract

A variety of battery-powered rotary brushes have been marketed for oral care, dish washing, and household cleaning applications. Here we discuss several additional uses for such products, including additional cleaning and personal care tasks.

Overview of Battery-powered Rotary Brush Technology

Electric motors that drive rotary brushes have long been used in a variety of AC-powered devices such as single- or dual-brush buffers, polishers, and cleaners. More recently, battery- powered rotary brush units have been marketed, some of which employ low-cost miniature motors such as the motor in the Crest SpinBrush® device (see http://www.spinbrush.com/ ) or the Dawn Power Dish BrushTM (see http://www.homemadesimple.com/dawn/dish_brush.shtml ) of Procter & Gamble.

Exemplary patents and patent applications dealing with electric brushes with rotary elements, including toothbrush configurations, are found in US Pat. No. 6,836,917, "Replaceable Head Electric Toothbrush and Connection Structure Therefor," issued Jan. 1, 2005 to L.A. Blaustein et al.; the US patent publications US20020020645A1, US20020032941A1, and US20020078514A1, all published under the title "Electric Toothbrush," by L.A. Blaustein et al.; and US20030226223A1, "High Efficiency Electric Toothbrush" by J.G. Chan. The application of P&G's rotary brush technology to dish cleaning is described in the article, "No More Scrub-a- Dub?," published Sept. 25, 2003 in Business Week Online, available at http://www.businessweek.com/smallbiz/content/sep2003/sb20030925_0894_sb010.htm .
