Built for Stairs & Upholstery. Proven Everywhere Else. Carpeted stairs and upholstery are some of the most time-consuming, physically demanding work in the trade. Hand brushes are slow. Drill brushes fight you, wear out wrists, and can leave inconsistent results when the operator gets tired. This tool was built to solve those two jobs specifically — and it carries that same advantage into tile, grout, auto detailing, and janitorial work.
