I have been looking for a mop that wasn't horrible for about 10 years. I've tried them all. All have been a huge disappointment. Normally the build is cheap or they just don't clean well. This is amazing. I was worried that the 15" would be too big, but it is perfect and it cuts my cleaning time in half. The shape of the head fits into weird spaces. The angled ends are perfect for corners. And it lays almost perfectly flat for cleaning under furniture. I use the dust mop every day instead of a broom and mop once a week or as needed. Water is all that is needed, but if you want to add some soap it works well too. I wring it out by hand and can control how much water goes onto the floor. A tight squeeze leaves so little water behind that the floor dries in minutes. The best thing is that I no longer use a dirty broom. The dust mop heads go in the washer and come out clean. By the adjustable handle and quickly switch between lengths as needed. My house has never been so clean, and it stays cleaner longer! I'll never by another mop or broom again!
