I bought a house recently and it came with a polaris 360 that was already installed to the pool. I noticed the pool has not been getting cleaner despite having the Polaris on for 10-12 hours a day. Upon checking, I realized that the Polaris isn’t really going anywhere. When inspecting further, I noticed that the wheels do not spin when the pump is on. I saw a YouTube video where the person was holding the Polaris in the pool and was counting the rpm for the wheels, but mine does not do that. Does anyone have any idea on what I should do? I’m completely new to all this.
