I bought the SPIN 800 True Clean Mop and Bucket system.
I like the convenience of not having to hand wring the mop : it is done all by the spinning in the water bucket it self ( very light and with handle) . The Pads : i still need to find out how long they last and their cost to replace ..the only disadvantage i notice the material might be too thin and some spots on the kitchen floor are not removed completely  as with my other hand wring cords woven mops ...
