washers have an option of a hydro twister type unit but if you don't have one and or you need a second unit we recommend that you go to buy one. When buying a hydro twister buy the larger of the two. There my be only a 5 inch difference in surface coverage but it is well worth it when you are trying to save time without cutting corners. Especially if you are cleaning concrete at a construction site or a large retail type box store, there is a lot of concrete and the faster you clean it the more money you will make. Think about it.
