I have this system of Vileda bought since I since I moved the Leifheit system can no longer use because it is more suited for very smooth surfaces such as laminate or PVC. Therefore, now I have this system since it bought this better mop heads for rough natural stone tiles are the clean it better. The system is great because you have to bend over without nassse or hands to get the floors can wipe wet. Unfortunately, a push-button device on the holder's after just eight weeks uprooted so that was no longer to be used. Return on Amazon and refund of the amount without any problem. However, it should be working urgently on this material error. Have bought the same system again and am now curious how long it keeps time.
