Query: Excellent pool vacuum!

We received the vacuumed within a few days and immediately put it to work. It is awesome! It crawls very well on it's own and you can see the dirt and algae it sucks up on the floor of the pool. We have an above ground pool 18 X 33 and we had to buy a couple of extra hose lengths to make it reach the entire length of the pool. I highly recommend this vacuum.
