Ok which do you prefer and why? or if you have another type not listed, please chime in.
We currently have the p-65. Not to thrilled with it actually. Noticed that it seems to work perfectly when we are running it and we are in the pool. As soon as we get out, about 10-15 min, later the sucker is curled up against the skimmer. VERY AGGRIVATING! And it doesn't seem to get all the sand out of the bottom.
