Note: Each color of the Drill Brush attachment corresponds to the type of bristles they have, and each one is best suited for a specific type of cleaning job (for example, the yellow brush has medium bristles, best used for bathroom cleaning — bathtubs, showers, tile, and porcelain). Be sure to check the listing for which color is best for your intended purpose before buying!
The drill isn’t included, but you can find a bunch of great ones on Amazon!

Promising review: “I let my tub get extra dirty on purpose because I knew this brush set was coming. In five minutes my tub was sparkling clean. This item is no joke. The flat brushes are awesome for big surfaces and the cone brush hits the hard to reach corners. I liked them so much I bought a set for my mom.” —Jason B.
