Thinking about a solar cover for the first time, opinions

We have never used one in all these years, just never saw the need with Florida sun doing plenty of heating on its own. But Gene keeps bringing up the water loss to evaporation and honestly our bill has crept up the last couple summers. Thinking about trying a solar cover before fall but I have no idea what I am doing here. Do they get heavy and awkward to pull on and off a 10k gallon pool by myself, or is that a two person job every time? And does it cause any trouble with a Polaris running underneath if I forget and leave it half on. Would love to hear from anyone who actually uses one before I spend the money.
