@ AnnaK: Thanks Anna, I guess I need to just stop worrying about it. If it does get out of level I guess I will just re-install it the correct way, i've put it up once, I guess I can put it up again. My hand vacuum wont stay on the floor when I push it across the pool floor. It keeps wanting to flip up at the swivel by the end of the handle. It seems to do a good job but I more less have to push it down and around the pool at the same time. Thanks for your help it is greatly appreciated.

@ Watermom: Thanks Watermom, I will check these out, I was just wanting to get one that does well when the pool floor isnt completely free of dips and depressions.

@ BigDave: Big Dave I am guessing if it picks up sticks it will pick up dirt in the depressions of my pool floor.
