Hi all, we have a 5 year old Pentair Legend Platinum pressure side cleaner and lately it doesn't seem to be doing it usual masterful job. It will suck up some leaves, and pressure out of the tail is definitely good (I get sprayed by it weekly if not paying attention . Two things I've noticed are that 1) the tail no longer sweeps side to side, and 2) the unit in general seems to float in the water rather than sinking to the bottom and driving. It does eventually get there and drive around, but seems like the difference between walking on Earth and walking on the Moon.
Side effect is that the leaves are collecting in a strip at the bottom of the pool that never gets distributed out by the tail, and the cleaner rarely goes right through it to pick up the leaves.
What do I look at first?
