Hi All,
I have an older Polaris with a standard 3 wheel config; am looking at upgrading to a tanktrax model as they are (I'm told) easier on the vinyl liner. Unfortunately the contractor I used in redoing the pool did not do such a great job in smoothing the vermiculite base under the new liner. In just 2 years I developed small holes (significant enough to affect water levels over a day or two) from the friction of the drive wheels on the vinyl. I have also looked at the Hayward models that use water propulsion as opposed to moving wheels and am looking for a little guidance to avoid more liner issues. Any ideas would be appreciated..........
