At first thought it seemed to me not to be a problem however if the water temp goes below 70 the hose stiffens and the robot effectiveness is decreased. There is an older thread on this but here is a succinct blurb on it:
If you run your pool cleaner when the weather is cooler, you’ll lose that benefit of having softened up the hose and cable by laying them out in the sun. They’ll harden up again, which will increase the probability of tangling.
The first solution is to avoid running your cleaner when the temperature dips below 70°F (21°C). If you absolutely have to run it in cool weather, try laying the hose and cable out in the sun for a little while before putting the cleaner in the pool. Then keep an eye on the cleaner as it works so you can untangle any knots as soon as they occur.

I have significant amount of pine straw. Leaves and creepy crawling and jumping beasts but over the winter with pool covered with a huge tarp called a pool cover the pool remains relatively free of solids. The cover is stretched tight and anchored with stakes. In the past we used the water filled things and placed them all around the edge of the cover but stopped that. I guess if your cover is automatic it doesn’t extend over the coping/deck. You could buy one of those pool cover aka tarps and try that on top of the auto cover.
