This will be the third season that I've had my PRP. It was the best 500.00 I've spent. I just drop it in once a week or after a t'storm and in 1 hr it has my 20 x 40 pool clean. It doesn't do my 90 degree corners very well but I just go around and brush the stuff out towards the center. I can also use the net pole to get it lined up with the wall and it will go straight down the walls.
I haven't brushed my walls or manual vaccuumed in two years. I know that is taking a chance but no problems so far!!! The cord tangling is a pain sometimes but still much much better that doing it manually. I hope this one will last long enough for them to make a rechargeable one that doen't have a cord. Good luck on your decision.
