Drillbrush is a small business founded by a car wash owner, Anthony LaPolla, who had carpal tunnel and needed a way to clean rims without the strain of hand scrubbing. Tony started selling the design in 2007 and has since expanded the product line to include varying stiffnesses to handle all sorts of cleaning tasks.
The set includes three brush head attachments: a flat 2-inch detail brush, a flat 4-inch brush for large surfaces, and a rounded brush for corners.
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.
