The power supply has a drop of rust by the two screws holding the cable connector ., this is my fault as it was left outside by the pool for the whole winter .The bag you see was clean when it was put in the cleaner , that's one hour's worth of dirt that was picked up making the pool spotless .the remote has 4 buttons, 1 right, 1 left, 1 forward/reverse and the program button, which makes it climb the walls ,if you don't hit the program button it will only do the bottom.The brushes do show some wear nd tear on them , I'm sure I'll get through this season with them , maybe even next .
