I think this is where I fail a bit... I do have a polaris sport that runs around the bottom... seems to get most dirt... but not all as when I do brush lots of stuff moves around in different areas.
But do you have to brush a pool no matter what. I guess I ask cause I always see brush while SLAMING, but I guess it is just a normal thing to do... and I forget.
I wish i bought a robot instead, but i didn't know anything at the time.
