Just dropped my Pool Bot into my Pool and it is doing what it says it does. We have a very odd shaped pool so we are trying to get the right settings. App does not work under water which is a hassle when you dont know that but fine when you do as you can set it just before dropping it in. Had a lot of stuff in the filters after the first run and you can see when it is getting full as the PoolBot lifts at the front. We have a large Beach area which is not suitable for the PoolBot so wall cleaning remains a manual job for us. A shame but that is more to do with our pool than the PoolBots fault. All in all quite happy - Would receive 5 stars from me if it worked in shallow water. Craig
