Review on Shieldpro Drill Brush Attachment Set: Ultimate Power Cleaning Scrub Brushes for Bathroom and Kitchen Surfaces, Grout, Tub, Shower, Tile, Corners, Automotive - Yellow by Brian Douglas

I wanted to give you the most honest assessment possible. As soon as they arrived I used one to clean the radiator that was outside with water in it. I went with the one that looks like a toilet brush, partly because of the curves of the radiator and partly because I would never let my drill get that close to toilet water, so I wouldn't use it for that. My cooler has can holders on the lid and clears it and the rest of the cooler quickly and easily, but the torque of the drill makes it difficult to control. The obvious solution would be to use it at a lower speed, but if you must do that you can just as easily and effectively clean it with a regular cleaning brush without straining your wrist. The next use was my shower, which was my reason for buying it, since mine, like most showers, has curves and narrow spaces. This is why they are so difficult to clean, and in hard water they are quite difficult to clean even with regular cleaning. Do NOT use flat brushes here! At least not near corners or curves! The slightest impact creates black streaks from the hard plastic on the brush. Something worked, the rest will be more difficult. I ended up going back to the toilet brush-like brush and it did its job pretty well, but again the problem was torque and lower speeds are pointless. For the price it was ok. It is best used on completely flat surfaces with no curves or corners. Also, it's very important (especially if you're using cleaning products) to pay attention to which direction the spray is going, and as with any drill, be sure to wear safety goggles!
