The water should be picked up fairly rapidly into the area surrounding the clean water bladder. Try checking the lint filter to fix your suction problem. It is located in the top clear plastic section (the one with the dial to switch from tool to floor use). One the under side of it there is a small (1 inch square) red filter with a little door on it. Flip open the door and it is probably clogged with hair, carpet fibre. etc.. Clean it out and you should have suction.
