SCRUB PADS FIRMLY ATTACHED - All scrub pads are backed with a layer of fleece fabric, so they can be firmly attached to the attachment, and will NOT become loose when in use (unlike most of other similar products in the market that the scrub pad always comes loose from the attachment). TWO DIFFERENT STIFFNESSES - The green ones are a bit stiffer and thicker than the red ones. The red pads are abrasive enough to clean your bathroom or kitchen floor very efficiently. If you need stronger scrubbing, try the green ones! FITS ANY CORDLESS DRILL - Features 1/4-inch quick change shaft that fits any cordless drill. WEAR RESISTANT & DURABLE - The scrub pads are easy to rinse clean and they will be ready for next use again. Saves your cleaning time and make it more fun! :) size: 4 Inch 1/4-inch quick change shaft that fits any cordless drill Scrub pads firmly attached to the drill attachment Two stiffness for different uses Easy to change the pad Works great on big flat areas Great time and elbow grease saver Material: fiber + plastic Color: green + red NOTE: 1. Make sure the brush is rotating CLOCKWISE when in use. 2. For safety, remember to wear goggle or eye protection in case cleaning agents are thrown from the brush as it spins. 3. Wet the scrubbing pad with water and then test it on a small area first before applying it on a large area. The metal shaft is detachable and it's packed separately in the package, so please check your package carefully to find the shaft. It's NOT on the drill attachment as you see in the product image.
