Product review (2 stars): Not for me!
It is not for me.  It takes quite a muscle to crank it.  Mine came with broken part where the crank is in contact with the frame.  I think it is a poor design and I can do better with hands and a cleaning board.  Besides, to close the top lid is not easy in order to catch the suction.  I tried several times using it and I find the bucket with soap and hands is more efficient.
