Review on YIHATA 4 Pack Drill Brush Attachments Set: Powerful Multi-Purpose Scrubber Kit for Grout, Floor, Tub, Shower, Tile, Bathroom, and Kitchen (3 Brushes with Extended Red) by Catherine Buhr

I bought it to use on stairs (rugs), carpets, sinks, bathtubs etc. I believe it worked as described (tested) for mat. Yellow is thicker and harder than white. I tried cleaning the bathroom and it didn't satisfy the cleaning. First, it is not easy to hold the weight of the drill for about 10 minutes. At one point I refused to clean the bathroom with a drill brush. If it's a guy who uses cars for detailing I'd say it might work (haven't tested it yet). This is a regular product, not for my carpet cleaning needs. Consider the weight of the drill.
