Drill Brush is a small business based in New York. It was started in 2007 by a former electrician with carpal tunnel syndrome who needed a way to clean without causing him harm. The set comes with a 2-inch flat brush, a 4-inch flat brush, and a round brush. The white is a soft bristle, best for wheels, carpet, upholstery, glass, and leather; the yellow is a medium bristle, best for bathroom, bathtub, shower, tile, and porcelain; the green is a medium bristle, best for kitchen, stoves, cabinets, countertops, and linoleum; the blue is a medium bristle, best for boats, pools, canoe/kayaks, hot tubs, and plastics; the red is a stiff bristle, best for outdoors, siding, brick, garage, and gutter; and the black is a hard bristle, best for grills, loose paint, furnaces, ovens, and industrial use.  The drill isn't included, but you can get a basic Black and Decker one  here .
