I wipe our bottoms (parquet and tiles) for many years with this system. Operation is simple. It works in fact with a little practice, without bending down to wring the mop. Unfortunately, the stems are the weak point. On several occasions we had to change stems because the screw mechanism failed.
Because now the Wringaufsatz was torn in the bucket, it was time for a new acquisition. The new speaker is the old man in every way, clear Best Buy!
