I have a 12 year old pool that has a regular white plaster finish. My Polaris 3900 slips and gets stuck with the wheels turning on the steps, or up against the steps without climbing over them. I put new wheels on the Polaris, but no help. Sometimes it will just sit in one place until it reverses, then starts slipping again in another spot. Does anyone know how to get more traction against the plaster? Does anyone make "snow" tires for a Polaris??
Thanks for your comments.
