Congratulations on making great progress, but unless your camera is introducing some cloudiness into the photo, you should be able to see your pool cleaner with much more clarity. See this photo where you can see the two floor drains in the deep end (about 6') and the pool cleaner (at about 4.5') viewing through a diagonal of water. Also look at this post where the pool surface is messy, but you can see the clarity of the water. Maintaining the appropriate chlorine level should continue to improve the water clarity (having the chlorine at shock level will get there faster). Keep us posted.
