Review on Ultimate Drill Brush Kit: White Soft for Leather, Glass, Carpet | Yellow Medium for Bathroom Surfaces | Red Stiff for Outdoor Deck, Patio - Top Cleaning Supplies by Gregory Popo

They work. I wish Revain would allow two word comments, but since I need to expand on that a bit, let's get started. They look robust, industrial. They should be for the price, of course, but there's no disappointment here. They have hex shanks so they don't slip in the drill chuck and can handle quite a bit of torque. I took the red (hard) one out of the box, attached it to my drill bit and started working on the bottom mud. linoleum floor. Cleaned it up in a hurry. I used to have to hand clean with a scotch brite sponge. I then attached a white soft bristle brush and buffed the shower, tub and chrome fixtures. Not just cleaned, but polished. Brilliant. Soapy water will disappear in a few minutes. Watch out for soap and dirt flying around the room if you run them at high speed. So I work slowly and push a little. I recommend one of the new brushless drills, they can last a long time, the motor brushes never wear out (which they lack), have plenty of torque, and last a long time on a single charge. . It also seems to have become quieter in operation.
